ADVANCES IN HIGH ENERGY PHYSICS, 2014 (SCI-Expanded)
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' q gamma (q = u, c) 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.
