Search for the Anomalous Interactions of Up-Type Heavy Quarks in $\gamma \gamma$ Collision at the LHC

Abstract

We investigate the anomalous interactions of heavy up-type quark t' in a $\gamma \gamma$ collision at the LHC. We have obtained 95% confidence level(CL)limit of $t^{\prime }q\gamma$ anomalous coupling by taking into account three forward detector acceptances: $0.0015<\xi <0.15$,$0.0015<\xi <0.5$, and $0.1<\xi <0.5$.
