Anomalous $HZ\gamma$ couplings in photon-induced collisions at the LHC

Abstract

We have examined $HZ\gamma$ vertex to obtain the limits on anomalous $a_{\gamma }$, $b_{\gamma }$ and ${\tilde{b}}_{\gamma }$ couplings in a model independent way through the $\gamma p$ collisions via the process $pp\to p\gamma p\to pHqX$. The sensitivities to the anomalous couplings can be obtained as $|b_{\gamma }|$, $|{\tilde{b}}_{\gamma }|\sim 10^{-3}$ for the integrated luminosity of $L_{int}=100{\mathrm{fb}}^{-1}$ at the LHC with $\sqrt{s}=14$ TeV.
