Using the helicity amplitude method and including a new scalar type interaction in the matrix element of the exclusive semileptonic Λb→Λτ+τ- decay, P-odd asymmetries with polarized and unpolarized heavy baryons are investigated. The result is obtained that the study of P-odd asymmetries can be promising for establishing the new scalar sector beyond the SM.
