$WWgamma/Z$ production in the Randall-Sundrum model at LHC and CLIC

AbstractWe study the $W^+W^-gamma(Z)$ productions at both the CERN Large Hadron Collider (LHC) and the Compact Linear Collider (CLIC) in the framework of the Randall-Sundrum (RS) model. The impacts of the virtual RS Kaluza-Klein (KK) graviton on these processes are studied and compared with the standard model (SM) background. We present the integrated and differential cross sections in both the RS model and the SM. The results show that the relative RS discrepancies at the CLIC differ from those at the LHC, particularly in the transverse momentum and rapidity distributions. We also find that the RS signature performance, as a result of the resonance character of the RS KK-graviton spectrum, is distinctively unlike that in the large extra dimensions (LED) model. We conclude that the CLIC with unprecedented precision and high center-of-mass energy has potential advantage over the LHC in exploring the effects of the RS KK-graviton on the $W^+W^-gamma(Z)$ production processes.
