Abstract: | |||||
We investigate the influence of the fourth generation quarks on the
double lepton polarizations forward-backward asymmetries in B\rar K∗ l+ l− decay. We obtain that for both (μ, τ) channels the magnitude and the sign of the differential
forward-backward asymmetries and the magnitude of the average
forward-backward asymmetries are quite sensitive to the 4th
generation quarks mass and mixing parameters. It can serve as a good
tool to search for new physics effects, precisely, to search for the
fourth generation quarks(t′, b′) via its indirect manifestations
in loop diagrams.
