Hunting for the charming beauty tetraquark $T_{bc}$: LHCb meets theory

Thursday 5 Oct 2023, 13:30 → 18:00 Europe/Zurich

4/S-030 (CERN)

Ivan BELYAEV (ITEP/MOSCOW), Lorenzo Capriotti (Università e INFN, Bologna (IT)), Mengzhen Wang (Università degli Studi e INFN Milano (IT))

In 2021, the LHCb collaboration reported the observation of doubly-charmed tetraquark $T_{cc}^{+}$. The $T_{bc}$ particle is never observed in experiment, and the search of it would be an interesting topic for LHCb in the next few years. This miniworkshop aims at dedicated discussions about these doubly-heavy tetraquarks to share ideas or results from both the theoretical and experimental community. 

Participants who need invitation letter for visa or institute purpose should contact the LHCb secretariat by email : lhcb.secretariat@cern.ch
