Search for the Anomalous Interactions of Up-Type Heavy Quarks inγγCollision at the LHC

Abstract

We investigate the anomalous interactions of heavy up-type quark t ′ in a γγ collision at the LHC. We have obtained 95% confidence level (C.L.) limit of t ′ qγ (q = u, c) anomalous coupling by taking into account three forward detector acceptances; 0.0015 < ξ < 0.15, 0.0015 < ξ < 0.5 and 0.1 < ξ < 0.5.
