DESCRIPTION:Speakers: Pavel Krokovny (Budkker INP and Novosibirsk State Un
 iversity)\nIn the Standard Model the three charged leptons are identical c
 opies of each other\, apart from mass differences\, and the electroweak co
 upling of the gauge bosons to leptons is independent of the lepton flavour
 . This prediction is called lepton flavour universality (LFU) and is well 
 tested in tree level decays\; any violation of LFU would be a clear sign o
 f physics beyond the Standard Model. Experimental tests of LFU in semilept
 onic decays of b hadrons and in rare b decays are highly sensitive to mode
 ls of New Physics in which new\, heavy particles couple preferentially to 
 the 2nd and 3rd generations of leptons. Such models often also predict cha
 rged lepton flavour violation (CLFV). Recent results from LHCb on LFU in s
 emileptonic b → clν transitions and rare b->sll decays are discussed\, 
 along with searches for CLFV.\n\nhttps://indico.particle.mephi.ru/event/22
