Discovering SUSY with in the First LHC Physics Run
Arvind Rajaraman, Bryan T. Smith
In minimal supergravity, the parameter space where the slepton is the LSP is usually neglected, because of strong constraints on charged dark matter. When the gravitino is the true…
Searching for CPT violation in top anti-top production
J. A. R. Cembranos, A. Rajaraman, F. Takayama
We analyze the possibility of observing CPT violation in the top sector. We present current bounds on CPT violation in this sector, and analyze the prospects of improving these bou…
Big Bang Nucleosynthesis with Bound States of Long-lived Charged Particles
Manoj Kaplinghat, Arvind Rajaraman
Charged particles (X) decaying after primordial nucleosynthesis are constrained by the requirement that their decay products should not change the light element abundances drastica…
Collider Signatures of SuperWIMP Warm Dark Matter
Jose A. R. Cembranos, Jonathan L. Feng, Arvind Rajaraman +2
SuperWeakly-Interacting Massive Particles (superWIMPs) produced in the late decays of other particles are well-motivated dark matter candidates and may be favored over standard Wea…
Effective Dynamics of the Matrix Big Bang
Ben Craps, Arvind Rajaraman, Savdeep Sethi
We study the leading quantum effects in the recently introduced Matrix Big Bang model. This amounts to a study of supersymmetric Yang-Mills theory compactified on the Milne orbifol…
Stable Models of superacceleration
Manoj Kaplinghat, Arvind Rajaraman
We discuss an instability in a large class of models where dark energy is coupled to matter. In these models the mass of the scalar field is much larger than the expansion rate of…
