Study of Υ(10753) decays to π$^{+}$π$^{−}$Υ(nS) final states at Belle II
[arXiv:2401.12021]
We present an analysis of the process e$^{+}$e$^{−}$ → π$^{+}$π$^{−}$Υ(nS) (where n = 1, 2, or 3) reconstructed in 19.6 fb$^{−1}$ of Belle II data during a special run of the SuperKEKB collider at four energy points near the peak of the Υ(10753) resonance. By analyzing the mass distribution of the π$^{+}$π$^{−}$Υ(nS) system and the Born cross sections of the e$^{+}$e$^{−}$ → π$^{+}$π$^{−}$Υ(nS) process, we report the first observation of Υ(10753) decays to the π$^{+}$π$^{−}$Υ(1S) and π$^{+}$π$^{−}$Υ(2S) final states, and find no evidence for decays to π$^{+}$π$^{−}$Υ(3S) [...]

Simultaneous Determination of Fragmentation Functions and Test on Momentum Sum Rule
[arXiv:2401.02781]
We perform a simultaneous global analysis of hadron fragmentation functions (FFs) to various charged hadrons (π±, K±, and p/p¯) at next-to-leading order in QCD. The world data include results from electron-positron single-inclusive annihilation, semi-inclusive deep inelastic scattering, as well as proton-proton collisions including jet fragmentation measurements for the first time, which lead to strong constraints on the gluon fragmentations. [...]

Metadata at DESY Library: Metadata for physics experiment within DESY and outside of DESY
202433. DESY Bibliothekskommission, DESY Bibkom, Deutsches Elektronen-SynchrotonHamburg, Deutsches Elektronen-Synchroton, Germany, 11 Dec 2024 - 11 Dec 20242024-12-112024-12-11
[10.3204/PUBDB-2024-07607]
In this talk, we discuss the metadata-related topics that happen at Deutsches Elektronen-Synchroton DESY, including the metadata work that generates metadata records for the DESY ALPII experiment. Also an introduction of the NAPMIX (Nuclear, Astro, and Particle Metadata Integration for eXperiments) project that we closely collaborate with FAIR GSI and many other scientific institutes around Europe
