Restrictions from the neutralKandBmeson systems on left-right-symmetric gauge theories

Abstract

We investigate constraints on flavor-changing neutral-Higgs-boson masses and couplings in left-right-symmetric gauge theories which arise from the neutral $K$ and $B$ meson systems. The mass of such bosons must be in the multi-TeV region to avoid unacceptably large $K^0-{\overline{K}}^0$ or $B^0-{\overline{B}}^0$ transition amplitudes.
