Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Claudio Magris: un germanista dall’aula ai giornali

Claudio Magris ha portato avanti la sua ricerca universitaria come germanista in parallelo alla sua attività di publicista sui quotidiani. Inizialmente non si trattava degli stessi argomenti anche se nel corso del tempo gli articoli giornalistici diventeranno parte dei suoi libri. Il presente articolo dà conto di moltissimi dei pezzi pubblicati durante i primi anni (impossibile, qui, riferire di tutti), mettendo così in rilievo i temi da lui letti e studiati, e parla dei suoi maestri: Giovanni Getto, Leonello Vincenti, Sergio Lupi. A essi si aggiungono la figure di Ladislao Mittner e Giuliano Baioni. Le indagini sull’idea di Mitteleuropa nella letteratura moderna proseguono gli autori di origine ebraica ad essa. Magris intende la letteratura nel suo contesto storico, da qui l’importanza della storia nei suoi lavori. Docente alle Università di Torino e Trieste, nelle sue lezioni affronta anche autori contemporanei e viventi, come I.B. Singer e E. Canetti. Ma la ricerca germanistica di Magris oltrepassa sempre il recinto delle aule universitarie per farsi conoscere della società italiana
