Charged higgs contributions to rare weak processes in a supergravity model

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Charged Higgs contributions to\(Z^0 \to b\bar s + \bar bs\) andb are examined in a no-scaleN=1 suppergravity model taking into account the constraints typical of the model. Even with these rather restrictive constraints, such contributions can very well dominate over the gluino-induced effects.
