New new physics probes with Λb → Λc (→ π Λ) ℓν — •Ahmet Kokulu, Danny van Dyk, and Philipp Böer — Technische Universität München, James-Franck-Straße 1, D-85748 Garching, Germany
We calculate the four-differential decay rate for the cascade Λb → Λc (→ Λ π ) ℓ ν for the full set of b → c ℓ ν operators up to dimension six. Our work extends earlier studies in this respect. We find the cascade to provide complimentary constraints compared to those arising in B→ D(*), Bc→ℓν.
