Here’s the dead cone, finally!

Declustering D$^{0}$-meson tagged jets in pp collisions allows for the dynamic reconstruction of gluon emissions in the charm-quark shower, exposing the suppressed emission phase-space known as the dead-cone: arXiv.

ALICE physics briefing for LHCP2021: 7-12 June 2021

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.

Insight on the strong interaction of p-K pairs

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.

Hadron formation differs outside of jets

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.

ALICE measures light neutral mesons to high transverse momentum

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.
