On the angular distribution of Λ b → Λ(→ N π)τ +τ − decay
Abstract We present a full angular distribution of the four body Λ b → Λ(→ N π)ℓ+ℓ− decay where the leptons are massive and the Λ b is unpolarized, in an operator basis which includes the Standard Model operators, new vector and axial-vector operators, and scalar and pseudo-scalar operators. The ang...
