One-loop calculations for Hrightarrow fbar{f}γ in the U(1)_(B-L) extension for Standard Model

In this paper, we present the calculations for $H\rightarrow f\bar{f}\gamma$ in the $U(1)_{B-L}$ extension for Standard Model. Analytic results for one-loop form factors in the decay process are expressed in terms of the scalar one-loop Passarino$-$Veltman functions in the conventions of {\tt LoopTools}. Therefore, the decay rates can be evaluated numerically by using this package. In phenomenological results, we show the differential decay rates with respect to invariant mass of fermion pair $m_{ff}$, new neutral gauge mass $M_{Z'}$ and the coupling $g'$ of $U(1)_{B-L}$ gauge group. We find that the contributions of the $U(1)_{B-L}$ extension for Standard Model are visible effects and they must be taken into account at future colliders.
