Probes of universal extra dimensions at colliders
Probes of universal extra dimensions at colliders
In the universal extra dimensions model of Appelquist, Cheng, and Dobrescu, all of the standard model fields are placed in the bulk and thus have Kaluza-Klein (KK) excitations. These KK states can only be pair produced at colliders due to the tree-level conservation of the KK number, with the lightest …
