Exotic Heavy Hadrons at LHCb

Dr. Vanya Belyaev
ITEP Moscow

Virtual only

Faculty Host: Eric Braaten

Abstract: In the almost 20 years since the discovery of the enigmatic X(3872) meson in 2003, more than 30 exotic heavy-flavor hadrons that do not fit into the simple quark-antiquark and three-quark structures predicted by the Quark Model (and postdicted by QCD) have been observed. A large fraction of them, including the first representatives of two totally new classes of hadrons -- charm-anticharm pentaquarks and double-charm tetraquarks -- have been observed by the LHCb experiment at the Large Hadron Collider at CERN. The LHCb experiment has collected about 9 fb^-1 of data in proton-proton collisions at center-of-mass energies of 7, 8 and 13 TeV in the years 2010-2018, and it is currently preparing for the LHC Run-3 data-taking period. The most recent LHCb results on heavy-flavor exotic hadrons, their possible interpretations, and the expectations from Run 3 will be discussed.
