Fermion mass effects on $\Gamma (Z\text{ra}b\bar{b}+alightHiggs)$ in a two-Higgs-doublet model

Abstract

Large fermion mass effect on the Yukawa process $Z\text{ra}b\bar{b}\text{ra}b\bar{b}h(A)$ in the entire range of the neutral Higgs boson masses is found. It is particularly important for light Higgs bosons, which are still not excluded experimentally in a general two-Higgs-doublet model.
