Probing new physics in Λ

\nWe study the 4-body angular distribution for Λb → Λc+(→ Λπ+)ℓ−<overline>ν</overline> decays and discuss various asymmetric and angular observables in the Standard Model and the new physics scenarios. Considering the new physics effects in b → cτ−<overline>ν</overline>τ transitions, we have constrained the new Wilson coefficients of the one operator and two operator scenarios from the available data on these decays. The two-operator scenario with scalar-pseudoscalar and tensor quark current provides the most plausible solution to the current data. Also, we have tested the new physics sensitivities (one or two-operator scenarios) of the different angular observables in Λb → Λc(→ Λπ+)τ−<overline>ν</overline>τ decays and found correlations among them.\n
