Phenomenology of Two Higgs Doublet Models with Flavor Changing Neutral Currents

Abstract

A comprehensive phenomenological analysis of a two Higgs doublet model, with flavor changing scalar currents at the tree level, called model III, is presented. Constraints from existing experimental information especially on (Delta F)=2 processes are systematically incorporated. Constraints emerging from rare B-decays, Z-->b\bar b, and the ρparameter are also examined. Experimental implications for e^+e^- (μ^+μ^-)-->t\bar c+\bar t c, t-->cγ(Z,g), D^0-\bar D^0, and B^0_s-\bar B^0_s oscillations, and for e^+e^-(Z)-->b\bar s+s\bar b are investigated and experimental effort towards these is stressed. We also emphasize the importance of clarifying the experimental issues pertaining to Z-->b\bar b.
