UNI 11535:2014 and UNI 11536:2014 standards: professional profiles of librarian and archivist

The paper presents the two national standards on the professional profiles of librarian and archivist published in July 2014 by UNI (Ente Italiano di Normazione) under the responsibility of the UNI – Documentation and information technical committee.- Paola Manoni presents the structure and schedule of the UNI – Documentation and information technical committee, along with its main initiatives.- Giovanna Merola outlines how – since 2000 – UNI has carried out a series of standards on non-regulated professions. UNI’s purpose is to define – on the basis of the European directives and of the European Qualification Framework – the general structure of the standards in order to ensure transparency and consistency. The technical committee UNI – Documentation and information, with its Working Group 7 – Evaluation of professions related to the management of data and documents, has so far produced two standards on the professional profiles of librarian and archivist.- Flavia Cancedda describes the UNI 11535:2014 standard, defining the activity of librarian in compliance with the provisions of the law 4/2013 on not organized professions. Both the law and the UNI standard give a new and substantial chance to librarians, providing them with the opportunity to adequately enhance their know-how and to gather the different professional associations under a unique professional standard, now legally recognized. The paper outlines the Italian and European rules, as well as the context in which the UNI standard was developed, and illustrates its benefits and future applications in the labor market. Finally, a few significant steps of the standard are analyzed more in detail.- Giovanni Michetti shows how the EQF model has been applied to develop the UNI 11536:2014 standard, aimed at identifying the essential competences, skills and knowledge of the archivist’s profession. He provides an overview of the standard UNI 11536:2014, that may serve different needs – from updating and re-designing professional training and curricula, to raising awareness about the archivist’s role in the information and documentation processes.Scopo dell’articolo è la presentazione delle due nuove norme tecniche nazionali dedicate alla definizione delle figure professionali di bibliotecario e archivista, pubblicate nel luglio 2014 dall’UNI (Ente Italiano di Normazione) sotto la responsabilità della Commissione UNI Documentazione e informazione.L’articolo è organizzato in diverse sezioni:- Paola Manoni presenta l’articolazione, gli obiettivi della Commissione UNI Documentazione e informazione e le sue più importanti iniziative.- Giovanna Merola illustra come, a partire dagli anni 2000, l'UNI porti avanti una serie di norme riguardanti le professioni non regolamentate, definendo le caratteristiche e l’impostazione di tali norme sulla base di direttive europee e dell’European Qualification Framework, in modo da garantirne trasparenza e omogeneità. La Commissione Documentazione e informazione, con il Gruppo di lavoro 7 sulla qualificazione delle professioni per il trattamento di dati e documenti, ha finora prodotto due norme riguardanti le professioni di bibliotecario e di archivista.- Flavia Cancedda presenta la norma UNI 11535:2014 sulla figura professionale del bibliotecario. Si tratta della prima norma italiana che – in adempimento a quanto previsto dalla legge 4/2013 sulle professioni non organizzate – definisce nello specifico le caratteristiche dell’attività bibliotecaria. Sia la legge 4/2013 che lo standard UNI costituiscono un’opportunità del tutto nuova per i professionisti del settore, che hanno ora la possibilità di valorizzare adeguatamente il proprio know-how e di compattare le organizzazioni di categoria attorno a un ruolo professionale definito e riconoscibile. Il contributo accenna al contesto normativo nazionale ed europeo, nonché al contesto UNI in cui la norma è stata predisposta dall’apposito gruppo di lavoro; indica le opportunità derivanti dall’esistenza di questo standard e le sue eventuali applicazioni sul mercato del lavoro; infine analizza alcuni passaggi particolarmente rilevanti della norma.- Giovanni Michetti mostra come il modello EQF (European qualification framework) sia stato applicato alla professione dell'archivista per la norma UNI 11536:2014, mirata a individuare le caratteristiche di rilievo del profilo professionale archivistico. Per la prima volta una norma tecnica definisce in maniera formale competenze, abilità e conoscenze necessarie per svolgere la professione di archivista, e come tale può essere utilizzata per diverse finalità: dall’aggiornamento e dalla riprogettazione di percorsi formativi e professionali alla sensibilizzazione sul ruolo degli archivisti nei processi informativi e documentali

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe

Measurement of nuclear modification factors of gamma(1S)), gamma(2S), and gamma(3S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead-lead (PbPb) and proton-proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date. © 2019 The Author(s).

Measurement of b jet shapes in proton-proton collisions at root s=5.02 TeV

We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 27.4 pb(-1). To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.Peer reviewe

Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV

A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.Peer reviewe

Measurement of the Jet Mass Distribution and Top Quark Mass in Hadronic Decays of Boosted Top Quarks in pp Collisions at root s=13 TeV

A measurement is reported of the jet mass distribution in hadronic decays of boosted top quarks produced in pp collisions at root s = 13 TeV. The data were collected with the CMS detector at the LHC and correspond to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lepton + jets channel of t (t) over bar events, where the lepton is an electron or muon. The products of the hadronic top quark decay t -> bW -> bq (q) over bar' are reconstructed as a single jet with transverse momentum larger than 400 GeV. The t (t) over bar cross section as a function of the jet mass is unfolded at the particle level and used to extract a value of the top quark mass of 172.6 +/- 2.5 GeV. A novel jet reconstruction technique is used for the first time at the LHC, which improves the precision by a factor of 3 relative to an earlier measurement. This highlights the potential of measurements using boosted top quarks, where the new technique will enable future precision measurements.Peer reviewe
