Extra-dimensional gravity and dijet production at [formula presented] colliders

Research output: Contribution to journalArticlepeer-review


In this Brief Report, we consider dijet production at (Formula presented) colliders as a probe of recently proposed, large extra-dimensional gravity models. The exchange of virtual, spin-2 graviton towers (Kaluza-Klein excitations) significantly modifies the cross section, as compared to the standard model predictions. We find that, in order to maximize the value of the effective scale that can be probed at a given center-of-mass energy, a very severe (Formula presented) cut should be applied; in general, a (Formula presented) equal to approximately (Formula presented) of the (Formula presented) beam energy gives the highest reach. We find that we can probe the effective mass scale from about (Formula presented) to (Formula presented) depending on the center-of-mass energy and assumptions about the model.
