چکیده

We study the process ee → ee at a high energy ee collider including the effect of graviton exchanges in the warped gravity model of Randall and Sundrum. Discovery limits for gravitons are established and the effects of polarization are discussed.

Testing the seesaw mechanism at collider energies in the Randall-Sundrum model

The Randall-Sundrum model with gauge fields and fermions in the bulk has several attractive features including the gauge coupling unification, a candidate for the dark matter, and an explanation for the hierarchical Yukawa couplings. In this paper, we point out that the 1st Kaluza-Klein modes of right-handed neutrinos may be produced at colliders, for both Dirac and Majorana neutrino cases. Fur...

GRAVITON RESONANCES IN ee → μμ AT LINEAR COLLIDERS WITH BEAMSTRAHLUNG & ISR EFFECTS

Electromagnetic radiation emitted by the colliding beams is expected to play an important role at the next generation of high energy e+e− linear collider(s). Focusing on the simplest process e+e− → μ+μ−, we show that radiative effects like initial state radiation (ISR) and beamstrahlung can lead to greatly-enhanced signals for resonant graviton modes of the Randall-Sundrum model.

Kaluza - Klein Physics at Muon Colliders 1

We discuss the physics of Kaluza-Klein excitations of the Standard Model gauge bosons that can be explored by a high energy muon collider in the era after the LHC and TeV Linear Collider. We demonstrate that the muon collider is a necessary ingredient in the unraveling the properties of such states and, perhaps, proving their existence. The possibility of observing the resonances associated wit...

Precision Measurements and Fermion Geography in the Randall-Sundrum Model Revisited

We re-examine the implications of allowing fermion fields to propagate in the fivedimensional bulk of the Randall-Sundrum (RS) localized gravity model. We find that mixing between the Standard Model top quark and its Kaluza Klein excitations generates large contributions to the ρ parameter and consequently restricts the fundamental RS scale to lie above 100 TeV. To circumvent this bound we prop...

Radion Couplings to Bulk Fields in the Randall-Sundrum Model

The radion may be the lightest new state present in the Randall-Sundrum(RS) model. We examine the couplings of the radion to the Standard Model(SM) fields in the scenario where they propagate in the bulk and expand into Kaluza-Klein towers. These couplings are then contrasted with those of the more familiar case where the SM fields are confined to the TeV brane. We find that the couplings of th...
