More and More Indirect Signals for Extra Dimensions at More and More Colliders
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 se...

متن کاملMore Transverse Polarization Signatures of Extra Dimensions at Linear Colliders
Polarization of both electron and positron beams at a future linear collider (LC) allows for the measurement of transverse polarization asymmetries. These asymmetries have been shown to be particularly sensitive to graviton or other spin-2, s−channel exchanges in the process e+e− → f f̄ (f = e) which allows for a doubling of the usual search reach. A question then arises as to whether other e+e−...
متن کاملEXTRA DIMENSIONS AND MORE... a
One of the most stimulating recent ideas in particle physics involves a possibility that our universe has additional compactified spatial dimensions, perhaps as large as 1 mm. In this review, we discuss the results of recent experimental searches for such large extra dimensions, as well as new developments in this field. The possibility that the universe has more than three spatial dimensions h...
