摘要：

In left-right symmetric models, large contributions to the decay amplitude b --> sgamma can arise from the mixing of the W(L) and W(R) gauge bosons as well as from the charged Higgs boson. These amplitudes are enhanced by the factor m(t)/m(b) compared to the contributions in the standard model. We use the recent CLEO results on the radiative B decay to place constraints on the W(L) - W(R) mixing angle zeta and the mass of the charged Higgs boson m(H+/-). Significant departures from the standard model predictions occur when \zeta\ greater than or similar to 0.003 and/or when m(H+/-) less than or similar a few TeV.
