More and More Indirect Signals for Extra Dimensions at More and More Colliders
نویسنده
چکیده
It has been recently suggested by Arkani-Hamed, Dimopoulos and Dvali that gravity may become strong at energies not far above the electroweak scale and thus remove the hierarchy problem. Such a scenario can be tested at both present and future accelerators since towers of Kaluza-Klein gravitons and associated scalar fields now play an important phenomenological role. In this paper we examine several processes for their sensitivity to a low scale for quantum gravity including deep inelastic ep scattering at HERA, high precision low energy νN scattering, Bhabha and Moller scattering at linear colliders and fermion pair production at γγ colliders. ∗Work supported by the Department of Energy, Contract DE-AC03-76SF00515

متن کاملExtra Dimensional Signatures at CLIC
Many models predict the existence of additional spatial dimensions that lead to new and distinct phenomenological 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 of the three following classes: (i) the large extra dimensions scenario of Arkani-Hamed, Dvali and Dimopoulos(ADD)[1]. This model predict...
متن کاملSearches for hyperbolic extra dimensions at the LHC
In this poster, we present a model of large extra dimensions where the internal space has the geometry of a hyperbolic disc. Compared with the ADD model, this model provides a more satisfactory solution to the hierarchy problem between the electroweak scale and the Planck scale, and it also avoids constraints from astrophysics. Since there is no known analytic form of the Kaluza–Klein spectrum ...
