DESCRIPTION:Speakers: Ivan Sukhanov (Faculty of Physics\, M.V.Lomonosov Mo
 scow State University\; Federal Research Center "Computer Science and Cont
 rol"\, Russian Academy of Sciences)\nRecently the number of experimentally
  observed Υ mesons significantly increased. This opens the possibility to
  observe their weak decays. In this talk semi- and non-leptonic Υ decays 
 are studied within the framework of the relativistic quark model based on 
 the quasipotential approach and quantum chromodynamics. The form factors a
 re obtained and their dependence on the square of the transferred momentum
  is explicitly determined in the accessible kinematic range. On the basis 
 of these form factors and factorization approximation\, semi- and non-lept
 onic decay rates of the Υ mesons are calculated. The detailed comparison 
 with other theoretical results is given.\n\nhttps://indico.particle.mephi.
