On the supersymmetric completion of the term in M-theory
Arvind Rajaraman
We examine the question of finding the supersymmetric completion of the term in M-theory. Using superfield methods, we present an eight derivative action in eight dimensions…
New Developments in Extra-dimensional Dark Matter
Jose A. R. Cembranos, Antonio Dobado, Jonathan L. Feng +3
We summarize the main features of several dark matter candidates in extra-dimensional theories. In particular, we review Kaluza-Klein (KK) gravitons in universal extra dimensions a…
Minimal Supergravity with m_0^2 < 0
Jonathan L. Feng, Arvind Rajaraman, Bryan T. Smith
We extend the parameter space of minimal supergravity to negative values of m_0^2, the universal scalar mass parameter defined at the grand unified scale. After evolving to the wea…
CPT violation in the top sector
J. A. R. Cembranos, A. Rajaraman, F. Takayama
We study the viability of observation of CPT violation in the top sector at future colliders. We show possible studies and different estimates for hadronic and linear colliders. In…
SuperWIMP Solutions to Small Scale Structure Problems
Jose A. R. Cembranos, Jonathan L. Feng, Arvind Rajaraman +1
Collisionless, cold dark matter in the form of weakly-interacting massive particles (WIMPs) is well-motivated in particle physics, naturally yields the observed relic density, and…
High-Energy Scattering in Non-Commutative Field Theory
Jason Kumar, Arvind Rajaraman
We analyze high energy scattering for non-commutative field theories using the dual gravity description. We find that the Froissart-Martin bound still holds, but that cross-section…
