Graviton Production By Two Photon Processes In Kaluza-Klein Theories With Large Extra Dimensions

TL;DR

This paper investigates how gravitons produced through two-photon fusion in Kaluza-Klein theories with large extra dimensions can be detected at colliders, providing bounds on the theories' parameters.

Contribution

It presents a new analysis of graviton production via two-photon processes in Kaluza-Klein models, deriving potential experimental bounds at future colliders.

Findings

Bounds on the gravitational interaction scale can reach 6-9 TeV at the Next Linear Collider.

Two-photon fusion processes can significantly constrain large extra dimension theories.

The study provides a method to test TeV-scale gravity models experimentally.

Abstract

We consider the production of gravitons via two photon fusion in Kaluza-Klein theories which allow TeV scale gravitational interactions. We find that the processes l+ l- to l+ l- + graviton, with l=electron or muon can put quite stringent bounds on such theories. For example, with two extra dimensions at the Next Linear Collider with a center of mass energy of 500 (1000) GeV attainable bounds on the scale of the gravitational interactions can reach about 6 (9) TeV.
