Crowdsourcing our Cultural Heritage, Edited by Mia Ridge

Crowdsourcing our Cultural Heritage provides a comprehensive view on the subject of working with our communities to increase our reach and enhance our collections. Though the book covers the entire GLAM sector (galleries, libraries, archives and museums), there’s much here to learn and consider for libraries who work in this space

Libraries and Public Perception: A Comparative Analysis of the European Press, By Anna Galluzzi

It’s not uncommon for libraries to prove their value to the communities they serve. Traditionally this comes through cost-benefit analyses or return-on-investment models. The problem with this sort of analysis is the focus on the quantitative and not the qualitative. ‘The price of everything, and the value of nothing,’ as Oscar Wilde might say

Towards a Step Change in Managing Research Data at Western Sydney University: Assessment of the Active Data Management Ecosystem

This paper describes the approach taken by Western Sydney University in the assessment of a turnkey research data management platform. Key recommendations from the Active Research Data Management Element of the Research Data Management Framework developed by the Australian Research Data Commons were implemented. WSU-derived research data are currently stored across many different silos and there is consideration of management of data through research data management plans. However, the use of metadata is not consistent and often non-existent. WSU trialled the use of the Idea package provided by Cloud Services provider Intersect, which is based on Mediaflux, for the management of research data throughout the full data lifecycle from collection to archiving. The Active Research Data Management Element provided useful insights into the assessment of Idea in the areas of data management, use of metadata, automated data workflows, research data governance and the criteria for platform selection

Metadata: A Case Study at Western Sydney University: Assessment of Metadata Schema for Active Research Data Management

Western Sydney University has engaged Cloud Services provider Intersect to provide access to Mediaflux on an Intersect research data management platform called Idea . Idea has been designed with the intention of managing research data throughout the full data lifecycle from collection to archiving. WSU-derived research data are currently stored across many different silos and there is consideration of management of data through research data management plans. However, the use of metadata is not consistent. As part of the Australian Research Data Commons (ARDC) National Data Assets Initiative, the ARDC funded a collaborative multi-university Institutional Underpinnings project to develop a national Institutional Research Data Management Framework (the Framework). Several essential Elements to the Framework were developed, one of which is the Active Research Data Management Element . The intention of this Element is to provide “institutions with guidance to ensure that research practice is efficient and impactful, and that research data is managed according to requirements such as those outlined in The Australian Code for the Responsible Conduct of Research”. Our approach at Western Sydney University in implementation of the Active Research Data Management Element of the Framework was to take the turnkey Idea platform, configure using a default metadata schema and engage with researchers in ingesting live research project datasets. This case study evaluates the metadata schema to reflect active research datasets uploaded directly from a data source to the Idea research data repository. The Idea platform provides the ability for researchers to curate, manage, protect and disseminate research data. It will also provide the capacity for handling data from research instrument platforms as increasingly, the University’s research infrastructure requires a component that automates metadata creation and storage for aspects of the research cycle

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

Measurement of the ratios of branching fractions R(D∗)\mathcal{R}(D^{*}) and R(D0)\mathcal{R}(D^{0})

The ratios of branching fractions $\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu})$ and $\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu})$ are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb${ }^{-1}$ of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode $\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}$. The measured values are $\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024$ and $\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066$, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is $\rho=-0.43$. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages

Measurement of CP asymmetries and branching fraction ratios of B− decays to two charm mesons

The $CP$ asymmetries of seven $B^-$ decays to two charm mesons are measured using data corresponding to an integrated luminosity of $9\text{fb}^{-1}$ of proton-proton collisions collected by the LHCb experiment. Decays involving a $D^{*0}$ or $D^{*-}_s$ meson are analysed by reconstructing only the $D^0$ or $D^-_s$ decay products. This paper presents the first measurement of $\mathcal{A}^{CP}(B^- \rightarrow D^{*-}_s D^0)$ and $\mathcal{A}^{CP}(B^- \rightarrow D^{-}_s D^{*0})$, and the most precise measurement of the other five $CP$ asymmetries. There is no evidence of $CP$ violation in any of the analysed decays. Additionally, two ratios between branching fractions of selected decays are measured.The CP asymmetries of seven B$^{−}$ decays to two charm mesons are measured using data corresponding to an integrated luminosity of 9 fb$^{−1}$ of proton-proton collisions collected by the LHCb experiment.
