The ALICE collaboration has used ultrarelativistic nuclear collisions to test the limits of hadronisation.
Precise measurements of the Z-boson production cross section by LHCb provide an implicit test of quantum chromodynamics.
The freshly-completed upgrade of the detectors and the harvest of Pb–Pb collision data expected in Run 3 will further improve the measurements.
A new measurement by the ALICE collaboration has demonstrated for the first time that jets become narrower after “quenching” in quark–gluon plasma.
The engagement of international partners and early-career scientists will be pivotal for successful delivery of the Electron–Ion Collider.
By measuring the transverse momentum of photon pairs, and related observables, the strong interaction may be indirectly probed.
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.
The workshop explored new perturbative results and methods in quantum field theory, collider physics and gravity.
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.
Charm fragmentation fractions presented today at EPS-HEP by the ALICE collaboration are the first such measurements at the LHC.
