RD53C Chip Manual / Garcia-Sciveres, Maurice (Lawrence Berkeley National Lab. (US)) /RD53 Collaboration
This manual provides a technical description of the RD53C chip design and operation adequate for simulation, testing, debugging and DAQ development. The Manual comes in two flavors: RD53C_ATLAS (also called ITkPix-V2) and RD53C-CMS (also called CROC-V2) [...]

Measurement of azimuthal anisotropy of the $\rm{f}_{0}(980)$ and $\rm{D}^{0}$ mesons in heavy ion collisions at CMS / Saha, Nihar Ranjan (Indian Inst. Tech., Madras) /CMS Collaboration
We present novel insights into the elusive $\rm{f}_{0}(980)$ hadrons quark composition and the interaction of heavy charm quarks with the quark-gluon plasma (QGP) through the anisotropic flow measurement of $\rm{D}^{0}$ in Heavy-Ion collisions. The $\rm{f}_{0}(980)$, whose precise configuration has remained controversial, is reconstructed for the first time via its dominant decay channel, $\rm{f}_{0}(980) \rightarrow \pi^{+}\pi^{-}$, using data from proton-lead collisions at 8.16 TeV, as collected by the CMS experiment.

First measurement of the $\nu_e$ and $\nu_\mu$ interaction cross sections at the LHC with the FASER$\nu$ detector /FASER Collaboration
This paper presents the first results of the study of high-energy electron and muon neutrino charged-current interactions in the FASER$\nu$ emulsion/tungsten detector at the LHC. A subset of the FASER$\nu$ volume, which corresponds to a target mass of 128.6~kg, was exposed to neutrinos from the LHC $p$-$p$ collisions with a centre-of-mass energy of 13.6~TeV and an integrated luminosity of 9.5 fb$^{-1}$.

Injection and capture of antiprotons in a Penning-Malmberg trap using a drift tube accelerator and degrader foil / Amsler, C. ; Breuker, H. ; Bumbar, M. ; Chesnevskaya, S. ; Costantini, G. ; Ferragut, R. ; Giammarchi, M. ; Gligorova, A. ; Gosta, G. ; Higaki, H. et al. /Asacusa AD-3
The Antiproton Decelerator (AD) at CERN provides antiproton bunches with a kinetic energy of 5.3 MeV. The Extra-Low ENergy Antiproton ring at CERN, commissioned at the AD in 2018, now supplies a bunch of electron- cooled antiprotons at a fixed energy of 100 keV. [...]

The first observation of the $B_c^+ \to J/\psi \pi^+ \pi^0$ decay is reported with high significance using proton-proton collision data, corresponding to an integrated luminosity of 9 fb$^{-1}$, collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV. [...]
