DESCRIPTION:Speakers: Tobias Huber\n\nRare and radiative decays of $B$ mes
 ons probe the SM directly at the quantum level and are therefore highly se
 nsitive to new phenomena. Among  them\, the inclusive radiative $\\bar B
  \\to X_s \\gamma$ decay is one of the standard candles in the indirect se
 arch for new physics. I report on two recent calculations that aim at impr
 oving the SM prediction of the decay rate. First\, multi-parton contributi
 ons formally complete the prediction at NLO\, second\, the interference of
  current-current into magnetic dipole operator was computed at NNLO for th
 e physical value of the charm-quark mass. I will discuss the size of these
  contributions\, present the updated SM prediction\, compare to experiment
 al measurements and present some implications for BSM searches.\n\nhttps:/
