Work now turns to connecting such observations with the known suppression and regeneration mechanisms in heavy-ion collisions.
The tetraquark candidate could be a bound state of a charm-up diquark and its anti-diquark.
Advances in Higgs, flavour and neutrino physics were among the highlights of ICHEP 2020, writes Mark Thomson.
CERN’s NA62 collaboration has presented 3.5σ evidence for K+→π+νν̄ – a “golden decay” with exceptional sensitivity to physics beyond the Standard Model
Originally scheduled to be held in Paris, the fully online conference brought together a particularly large and diverse group of participants.
LHCb results favour the interpretation of the state as a quasi-bound D0D*0 molecule.
A novel technique by ATLAS uses top-quark pairs to test the ratio of the probabilities for tau leptons and muons to be produced in W-boson decays
LHCb will soon become the first LHC experiment able to run simultaneously with two separate interaction regions.
The collaboration scoured four months of electron-positron collisions at SuperKEKB for evidence of invisibly decaying Z′ bosons.
Updated measurements by LHCb of the angular distributions of a rare neutral B meson decay add fresh intrigue to the flavour puzzle.
