The implication of the fourth-generation quarks in the B→K ~(*+-) (=μ,τ) decays when K * meson is longitudinally or transversely polarized is presented herein. In this context, the dependence of the branching ratio with polarized K * and the helicity fractions (f L,T) of K * meson were studied. It was observed that the polarized branching ratios as well as helicity fractions are sensitive to the new physics (NP) parameters, especially when the final-state leptons are tauons. Hence, the measurements of these observables at LHC can serve as a good tool to investigate the indirect searches of new physics beyond the standard model.
