We show that the exclusive decay B → K * γ can be related to the semileptonic decay B → ρe¯ ν using heavy-quark symmetry and SU (3) flavor symmetry. A direct measurement of the q 2-spectrum for the semileptonic decay can provide relevant information for the exclusive rare decay.

A summary of the most recent results on top quark physics obtained at Fermilab’s Tevatron proton-antiproton collider, operating at a centre of mass energy of 1.96 TeV, is presented. Measurements of the top pair and single top quark production cross sections, the investigation of top quark decay properties, the precision measurement of the top quark mass as well as searches for physics beyond th...
