Abstract
We studied the B K(2)^\ast(1430)l^+l^- decay in the Standard Model
with Fourth Generation (SM4). Using the form factors calculated recently
through perturbative QCD (pQCD) approach the decay rate, forward-backward
asymmetry and different lepton polarization asymmetries are examined in SM4
scenario. It is found that the theoretical value of decay rate including the
contributions of m\_t' and the new 4\times4 CKM (CKM4) matrix factors,
|V\_t'b^\astV\_t's|, is much different from the minimal standard model (SM)
predictions. Similar deviations from the minimal SM predications were observed
for the forward-backward asymmetry and different lepton polarization
asymmetries. The future measurement of this decay will provide an opportunity
for the detection of physics beyond the SM.
