Collider Signatures of Singlet Extended Higgs Sectors
Vernon Barger, Paul Langacker, Gabe Shaughnessy
We explore the collider signatures of the Higgs sectors in singlet-extended MSSM models. We find that even with reduced couplings due to singlet mixing, a significant portion of th…
String Scale Gauge Coupling Unification with Vector-like Exotics and Non-Canonical U(1)_Y Normalization
V. Barger, Jing Jiang, Paul Langacker +1
We use a new approach to study string scale gauge coupling unification systematically, allowing both the possibility of non-canonical U(1)_Y normalization and the existence of vect…
Top Quark Pairs at High Invariant Mass - A Model-Independent Discriminator of New Physics at the LHC
Vernon Barger, Tao Han, Devin G. E. Walker
We study top quark pair production to probe new physics at the LHC. We propose reconstruction methods for semileptonic events and use them to reconstruct the …
Singlet Extensions of the MSSM
Vernon Barger, Paul Langacker, Gabe Shaughnessy
The Higgs sector of the MSSM may be extended to solve the mu problem by the addition of a gauge singlet scalar field. We consider the consequences of the singlet on the Higgs and n…
Accelerating cosmologies tested by distance measures
V. Barger, Y. Gao, D. Marfatia
We test if the latest Gold set of 182 SNIa or the combined "Platinum" set of 192 SNIa from the ESSENCE and Gold sets, in conjunction with the CMB shift parameter show a preference…
Upgraded experiments with super neutrino beams: Reach versus Exposure
V. Barger, Patrick Huber, Danny Marfatia +1
We introduce exposure as a means to making balanced comparisons of the sensitivities of long-baseline neutrino experiments to a nonzero θ_{13}, to CP violation and to the neutrino…
