Polarized forward-backward asymmetries of lepton pair in B→ K₁ℓ⁺ℓ⁻ decay in the presence of New physics

الأصل · EN

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.
