A time-frequency method for acoustic scattering with trapping
Heather Wilber, Wietse Vaes, Abinand Gopal +1
A Fourier transform method is introduced for a class of hybrid time-frequency methods that solve the acoustic scattering problem in regimes where the solution exhibits both highly…

Unitarity bounds with subthreshold and anomalous cuts for -hadron decays
Abinand Gopal, Nico Gubernari
We derive a generalisation of the Boyd-Grinstein-Lebed (BGL) parametrization. Most form factors (FFs) in -hadron decays exhibit additional branch cuts -- namely subthreshold and…
