First Order Calculation of the Inclusive Cross Section pp to ZZ by Graviton Exchange in Large Extra Dimensions

Understand

We calculate the inclusive cross section of double Z-boson production within large extra dimensions at the Large Hadron Collider (LHC).

• Using perturbatively quantized gravity in the ADD model we perform a first order calculation of the graviton mediated contribution to the pp to ZZ cross section.
• At low energies (e.g.
• Tevatron) this additional contribution is very small, making it virtually unobservable, for a fundamental mass scale above 2500 GeV.
