Weak scale quantum gravity effects for gamma gamma -> ZZ in the TeV region

摘要

We consider the effect of massive spin-2 gravitons that occur as Kaluza-Klein excitations of the graviton in a Weak scale Quantum Gravity scenario on the process gammagamma --> ZZ, which in the Standard Model can proceed through loop diagrams. For a wide range of parameters, we show that the massive gravitons leave behind signatures that should be verifiable in a TeV scale scattering experiment. (C) 2002 Published by Elsevier Science B.V.
