Jet signals for low mass strings at the LHC

Luis A. Anchordoqui, Haim Goldberg, Satoshi Nawata +1

The mass scale M_s of superstring theory is an arbitrary parameter that can be as low as few TeVs if the Universe contains large extra dimensions. We propose a search for the effec…

Constraints on Unparticle Physics from Solar and KamLAND Neutrinos

Luis Anchordoqui, Haim Goldberg

Interest has been directed recently towards low energy implications of a non-trivial conformal sector of an effective field theory with an IR fixed point (Λ), manifest in terms of…

Light Higgses at the Tevatron and at the LHC and Observable Dark Matter in SUGRA and D Branes

Daniel Feldman, Zuowei Liu, Pran Nath

Sparticle landscapes in mSUGRA, in SUGRA models with nonuniversalities (NUSUGRA), and in D brane models are analyzed. The analysis exhibits the existence of Higgs Mass Patterns (HP…

Phase transition in the fine structure constant

L. Anchordoqui, V. Barger, H. Goldberg +1

Within the context of mass-varying neutrinos, we construct a cosmological model that has a phase transition in the electromagnetic fine structure constant αat a redshift of 0.5. Th…

Theory and Phenomenology of Exotic Isosinglet Quarks and Squarks

Junhai Kang, Paul Langacker, Brent D. Nelson

Extensions of the MSSM often predict the existence of new fermions and their scalar superpartners which are vectorlike with respect to the standard model gauge group but may be chi…

The Landscape of Sparticle Mass Hierarchies and Their Signature Space at the LHC

Daniel Feldman, Zuowei Liu, Pran Nath

The minimal supersymmetric standard model with soft breaking has a large landscape of supersymmetric particle mass hierarchies. This number is reduced significantly in well-motivat…
