Unitarity bounds with subthreshold and anomalous cuts for -hadron decays

A Gopal, N Gubernari - arxiv preprint arxiv:2412.04388, 2024 - arxiv.org
We derive a generalisation of the Boyd-Grinstein-Lebed (BGL) parametrization. Most form
factors (FFs) in $ b $-hadron decays exhibit additional branch cuts--namely subthreshold …
