摘要： Double polarized forward-backward asymmetries in B→K1(1270,1400)ℓ+ℓ− with ℓ=μ,τ decays are studied, using most general non-standard local four-fermi interactions, where the mass eigenstates K1(1270) and K1(1400) are the mixture of 1P1 and 3P1 states with the mixing angle θK. We have calculated the expressions of nine doubly polarized forward-backward asymmetries and it is presented that the polarized lepton pair forward-backward asymmetries are greatly influenced by the new physics. Therefore, these asymmetries are interesting tool to explore the status of new physics in near future, specially at LHC.
