Test of the chiral structure of the top-bottom charged current by the process b→sγ(Flavor Physics and Beyond the Standard Model)

Abstract

The chiral structure of the top-bottom charged current is examined by using the process b→sγ. The new CLEO results on the radiative B decay constrain the possible deviation from the V-A coupling to be less than a few percent in the sector of the W-boson and top and bottom quarks.
