Shoroku Ohnuma 1928–2024

Shoroku Ohnuma, who made significant contributions to accelerator physics in the US and Japan, passed away on 4 February 2024, at the age of 95.

CMS observes top–antitop excess

The signal could be caused by a quasi-bound top–antitop meson commonly called "toponium".

Educational accelerator open to the public

What better way to communicate accelerator physics to the public than using a functioning particle accelerator?

CMS peers inside heavy-quark jets

The CMS collaboration has shed light on the role of the quark mass in parton showers.

CDF addresses W-mass doubt

Ongoing cross-checks at the Tevatron experiment reinforce its 2022 measurement of the mass of the W boson, which stands seven standard deviations above the Standard Model prediction

Boost for compact fast radio bursts

New results from the CHIME telescope support the hypothesis that fast radio bursts originate in close proximity to the turbulent magnetosphere of a central engine.

Charm jets lose less energy

New results from the ALICE collaboration highlight the quark-mass and colour-charge dependence of energy loss in the quark-gluon plasma.

Breaking new ground in flavour universality

A new result from the LHCb collaboration further tightens constraints on the lepton-flavour-universality violation in rare B decays.

A new record for precision on B-meson lifetimes

As direct searches for physics beyond the Standard Model continue to push frontiers at the LHC, the b-hadron physics sector remains a crucial source of insight for testing established theoretical mode...
