Graviton Production By Two Photon Processes In Kaluza-Klein Theories With Large Extra Dimensions
David Atwood, Shaouly Bar-Shalom, Amarjit Soni
We consider the production of gravitons via two photon fusion in Kaluza-Klein theories which allow TeV scale gravitational interactions. We find that the processes l+ l- to l+ l- +…
CP-Violation in the Top Sector
S. Bar-Shalom, G. Eilam
We discuss the prospects - within several models - for the observation of CP-violation (CPV) in top decays and production. The outlook looks best for t -> bW at the LHC (MSSM CPV),…
Probing New Higgs-Top Interactions at the Tree-Level in a Future e^+e^- Collider
Shaouly Bar-Shalom
The possibility of observing large signatures of new CP-violating and flavor-changing Higgs-Top couplings in a future e^+e^- collider experiments such as e^+e^- -> t bar-t h, t bar…
Flavor Changing Transitions and the Top Quark in a Two Higgs Doublets Model; Application to e^+e^- --> t bar-c nu_e bar-nu_e, t bar -c e^+ e^-, t bar-c Z, t --> cW^+W^- and t --> cZZ
Shaouly Bar-Shalom
Extension of the SM with one extra Higgs doublet may give rise to flavor-changing-scalar coupling of a neutral Higgs to a pair of top-charm quarks. This coupling gives rise to a la…
