Multiboson threshold production by fermion-antifermion pair and hidden symmetry
Joanna Domienik, Piotr Kosinski
TL;DR
This paper investigates the threshold production of multiple Higgs particles by fermion-antifermion pairs, revealing a hidden symmetry that explains amplitude nullification at a specific mass relation.
Contribution
It introduces a hidden symmetry in the effective dynamics that accounts for nullified amplitudes in multiboson production at threshold.
Findings
Nullification of amplitudes at Higgs mass = 2 * fermion mass
Hidden symmetry explains special case nullification
Framework for multiboson threshold production
Abstract
We consider threshold production of arbitrary number of Higgs particles by fermion-antifermion pair. The nullification of amplitudes for the special case Higgs mass = 2 * fermion mass is explained in terms of hidden symmetry of the reduced effective dynamics.
