Theory Seminar: September 9th, 1pm EDT (hybrid)

Speaker: Ramona Vogt (LLNL and UC Davis)

Title: Status of Intrinsic Charm

Abstract: A nonperturbative charm production contribution, known as intrinsic charm, has been speculated since the 1980s. While it has yet to be satisfactorily proven, there have been recent tantalizing hints.  Several experiments, either taking data or planned, could provide definitive evidence in the next few years. Recent experiments that have taken J/ψ and D meson data include SeaQuest at Fermilab and SMOG at LHCb.  Future experiments such as NA60+ are in an energy regime where the intrinsic charm quark signa-ture could be large and unmistakable.  In this talk, the status of intrinsic charm is reviewed and model comparisons are made to available data.  Production of tetraquarks by intrinsic charm is also discussed.  See Refs. [1-4].

This work was performed under the auspices of the U.S.\ DoE by LLNL under Contract DE-AC52-07NA27344 and supported by LDRD projects 21-LW-034 and 23-LW-036.

See you tomorrow.
