The Physics of Beauty (& Charm [& $τ$]) at the LHC and in the Era of the LHC

Abstract

The recent successes of the SM do not weaken the arguments in favour of New Physics residing at the TeV scale. Finding and identifying it represents the prime challenge for a generation of high energy physicists. To differentiate between different scenarios of New Physics we need to analyze their impact on flavour dynamics. A continuing comprehensive program of heavy flavour studies instrumentalizing the high sensitivity of \cp analyses is intrinsically connected to LHC's core mission. In B decays we can typically expect no more than moderate deviations from SM predictions. $B_s$ transitions provide an {\em autonomous} access to New Physics not prejudiced by $ΔM(B_s)|_{exp}\simeq ΔM(B_s)|_{SM}$. Dedicated studies of charm and $τ$ decays offer unique opportunities to observe New Physics. One challenge is whether LHCb will be able to exploit LHC's huge charm production rate to probe for \cp asymmetries. Likewise, to which degree ATLAS/CMS can contribute to $B$ physics and to searches for $τ\to 3l$. Yet to saturate the discovery potential for New Physics in beauty, charm and $τ$ decays we will need a comprehensive high quality data base that only a Super-Flavour Factory can provide.
