Charm-strange mesons probe hadronisation

The freshly-completed upgrade of the detectors and the harvest of Pb–Pb collision data expected in Run 3 will further improve the measurements.

Quark–gluon plasma narrows jets

A new measurement by the ALICE collaboration has demonstrated for the first time that jets become narrower after “quenching” in quark–gluon plasma.

Partnership yields big wins for the EIC

The engagement of international partners and early-career scientists will be pivotal for successful delivery of the Electron–Ion Collider.

Low-invariant mass diphoton event candidate in 13 TeV collisions

Strongly unbalanced photon pairs

By measuring the transverse momentum of photon pairs, and related observables, the strong interaction may be indirectly probed.

COMPASS points to triangle singularity

The collaboration last week reported the first direct evidence for the long-sought interplay between hadron decays, downplaying the chances that the a₁(1420) is a new exotic hadron.

Loop Summit convenes in Como

The workshop explored new perturbative results and methods in quantum field theory, collider physics and gravity.

New tetraquark a whisker away from stability

The new state, announced today at EPS-HEP, had been held up since the 1980s as a prime candidate to be the first exotic hadronic state to be stable against strong decays.

A proton-proton collision in the ALICE detector

Charm breaks fragmentation universality

Charm fragmentation fractions presented today at EPS-HEP by the ALICE collaboration are the first such measurements at the LHC.

Experiment and theory trade blows at SQM 2021

The conference attracted over 300 participants to discuss the role of strange and heavy-flavour quarks in heavy-ion collisions and astrophysical phenomena.
