10 Mar 2013 | Abstract: | We 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. | Source: | arXiv, 1303.2307 | Services: | Forum | Review | PDF | Favorites |
