LHC Beauty Experiment Data Was Last Before Long Shutdown
Just before the Long Shutdown of the Large Hadron Collider (LHC) this month, the LHC beauty (LHCb) experiment took data from collisions between protons and ions for the first time during the recent lead-proton run.

“The detector's unique angular coverage will enable us to study strange, charm and also beauty quark production in regions not accessible to the other experiments,” says LHCb spokesperson Pierluigi Campana.
LHCb cannot operate and record data during ion-ion runs, because each collision between ions can generate so many secondary particles that it becomes difficult for the subdetectors to withstand the particle flux.
But as seen from of LHCb, the difficulty of detection work during the proton-ion run is not so different from what they usually manage during the normal proton-proton operation. “For LHCb, the hybrid beam configuration is almost as manageable as the proton-proton one,” says Campana. “This applies both to the detector and the trigger and to offline systems."
A few dedicated groups within the LHCb collaboration are now analysing data from the proton-ion run and could release the first results alreadz this summer.
