The ALICE Collaboration presents several new physics results at the 9th Large Hadron Collider Physics conference LHPC2021 this week (https://indico.cern.ch/event/905399/), as well as the ongoing major detector upgrade for the LHC Run 3, prospects for further upgrades for Run 4, and for a completely new heavy-ion detector for Run 5 and beyond.
Non-identical particle femtoscopy of kaon-proton pairs produced in Pb–Pb collisions at the LHC provides an accurate measurement of kaon–proton scattering parameters at low relative momentum: arXiv.
In a recent study, the ALICE Collaboration has studied baryon-to-meson ratios with a new twist: by studying the ratios in two parts of the events separately – inside jets and in the event portion perpendicular to a jet cone. arXiv.
Neutral pion and eta meson production cross sections at midrapidty were measured up to unprecedentedly high transverse momenta in proton-proton (pp) and proton-lead (p-Pb) collisions at √s_NN = 8 and 8.16 TeV, respectively. arXiv.
The beauty-quark production cross section was measured at midrapidity by the ALICE Collaboration in pp collisions at √s = 5.02 TeV through non-prompt D-meson measurements exploiting machine-learning classification techniques arXiv.
The ALICE collaboration's measurement of the coherent photoproduction of J/ψ and ψ’ at midrapidity: arXiv.
For the first time, the production of pions, kaons, (anti-)protons and φ mesons at midrapidity has been measured in Xe–Xe collisions: arXiv
