7. Why Flavor Physics? The first flavor of new phenomena often comes from flavor physics  Weak decays of light hadrons => existence of charm quark  CP violation => 3 rd quark family  B0 oscillation => heavy top quark B mesons are especially suitable for beyond SM searches  Large mass of b quark – stronger coupling to new particles  Abundant production  Well developed technique of experimental selection 6 G. Borissov
