DESCRIPTION:Speakers: Elena Savchenko (Federal Research Center ”Computer
  Science and Control”\, Russian Academy of Sciences  (FRC CSC RAS)\; Fac
 ulty of Physics\, Lomonosov Moscow State University (MSU))\nTetraquarks co
 ntaining two bottom quarks are studied in the framework of the relativisti
 c quark model based on the quasipotential approach and QCD. The tetraquark
  is considered as a bound state of a diquark and an antidiquark. The inter
 action quasipotential includes both spin-dependent and spin-independent re
 lativistic contributions. The finite size of the diquark is explicitly tak
 en into account. The obtained tetraquark masses are compared with the thre
 sholds of strong fall-apart decays into two mesons. States that may appear
  as narrow resonances in suppressed decay channels are identified.\n\nhttp
