The most elusive higgsinos

Supersymmetry has so far eluded discovery at the LHC, yet it retains strong theoretical appeal as an extension of the Standard Model, and potential hiding places remain.

Suppression grows with system size

The CMS collaboration compared high-transverse-momentum particle yields in oxygen–oxygen, neon–neon, xenon–xenon and lead–lead collisions.

Charm and beauty alike in fragmentation

By tracking how much of a jet’s momentum each hadron carries, the LHCb collaboration has now compared how charm, beauty and light quarks hadronise.

The flavour dependence of jet structures

In a recent analysis, the ALICE collaboration compared the yields of charged particles associated with electrons from heavy-flavour hadron decays with those of the light hadrons.
