Simple Implementation

Describing the lightest pseudoscalar mesons as bound states of quark and antiquark within the framework of an instantaneous Bethe–Salpeter formalism constructed such as to retain (in contrast to Salpeter’s equation) as much information on the relativistic effects provided by the full quark propagator as conceivable allows for a surprisingly simple implementation of their near masslessness mandatory for their interpretability as pseudo-Goldstone bosons related to the spontaneous breaking of the chiral symmetries of quantum chromodynamics.

We examine the Higgs boson low-energy theorems and their applications in the study of light Higgs boson interactions with mesons and baryons. In particular, we clarify how a new parameter (the A parameter) emerges when the chiral Lagrangian method is combined with the Higgs low-energy theorems to obtain predictions for the interaction of Higgs bosons and pseudoscalar mesons. The computation of the Higgs–nucleon coupling and the branching ratios for light Higgs boson production in the decays K → πH and η′ → ηH are illustrated.
