【 摘 要 】

Many models predict the existence of additional spatial dimensions that lead to new and distinct phenomeno-logical signatures for future colliders which have center of mass energies in the TeV range and above. Most of the models in the literature fall into one the three following classes: (i) the large extra dimensions scenario of Arkani-Hamed, Dvali and Dimopoulos (ADD). This model predicts the emission and exchange of large Kaluza-Klein(KK) towers of gravitons that are finely-spaced in mass. The emitted gravitons appear as missing energy while the KK tower exchange leads to contact interaction-like dimension-8 operators. (ii) A second possibility are models where the extra dimensions are of TeV scale in size.
