LHCb brings leptons into line
Simultaneous measurements of rare B-meson decays using the full LHC Run 1 and 2 data samples agree with the predictions of the Standard Model, superseding previous results that had indicated intriguing departures from the 50-year old theory

ATLAS moves into top gear for Run 3
In their first Run 3 results, the ATLAS collaboration measured two Standard Model processes: the production of Z bosons and top-quark pairs

ALICE estimates how transparent the Milky Way is to antimatter
The finding will help space- and balloon-based searches for antimatter that may have originated from dark matter
-
CAST-CAPP inches closer to axion dark matter
The CAPP axion haloscope at the CAST experiment has hunted for axions from the Milky Way’s “halo” of dark matter, and has narrowed down the theoretical space in which to look for these hypothetical particles

ATLAS measures Higgs boson’s decay width
The decay width is linked to the particle’s lifetime and if found to deviate from its predicted value could indicate the presence of new physics

First Run 3 physics result by CMS
CMS measured the top-quark pair production cross section

ALICE explores the hidden charm of quark–gluon plasma
The ALICE collaboration shows that different bound states of a charm quark and its antimatter counterpart are differently modified by quark–gluon plasma, opening new avenues for studying this special state of matter and its effects

ALICE pins down hypermatter properties
The collaboration’s latest study of a “strange”, unstable nucleus known as the hypertriton offers new insight into the particle interactions that may take place at the hearts of neutron stars
