Generalized modified gravity in large extra dimensions
We discuss effective interactions among brane matter induced by modifications of higher-dimensional Einstein gravity through the replacement of Einstein-Hilbert term with a generic function f ( R, RA B RA B, RA B C D RA B ...
Non-gravitating scalars and spacetime compactification
We discuss role of partially gravitating scalar fields, scalar fields whose energy-momentum tensors vanish for a subset of dimensions, in dynamical compactification of a given set of dimensions. We show that the resulting ...
Correlating μ parameter and right-handed neutrino masses in N = 1 supergravity
The minimal supersymmetric standard model, when extended to embed the seesaw mechanism, obtains two dimensionful parameters in its superpotential: the μ parameter and the right-handed neutrino mass MN. These mass parameters, ...
CERN LEP indications for two light Higgs bosons and the U(1)′ model
(American Physical Society, 2006-01)
Reanalyses of LEP data have shown preference to two light CP-even Higgs bosons. We discuss implications of such a Higgs boson spectrum for the minimal supersymmetric model extended by a standard model singlet chiral ...
Renormalization group invariants in the MSSM and its extensions
(IOP Publishing, 2005-11)
We derive one-loop renormalization group (RG) invariant observables and analyze their phenomenological implications in the MSSM and its μ problem solving extensions, U(1)′ model and NMSSM. We show that there exist several ...
Minimal U(1)′ extension of the minimal supersymmetric standard model
(American Physical Society, 2005-07)
Motivated by the apparent need for extending the minimal supersymmetric standard model (MSSM) and perhaps mitigating naturalness problems associated with the μ parameter and fine-tuning of the soft masses, we augment the ...
Nonlinearly realized local scale invariance: Gravity and matter
That the scalar field theories with no dimensional couplings possess local scale invariance (LSI) via the curvature gauging is utilized to show that the Goldstone boson, released by the spontaneous LSI breakdown, is swallowed ...
Higher curvature quantum gravity and large extra dimensions
We discuss effective interactions among brane matter induced by modifications of higher dimensional Einstein gravity via the replacement of Einstein-Hilbert term with a generic function f(R) of the curvature scalar R. After ...
Neutralino dark matter in the left-right supersymmetric model
(American Physical Society, 2006)
We study the neutralino sector of the left-right supersymmetric model. In addition to the possibilities available in the minimal supersymmetric model, the neutralino states can be superpartners of the U(1)B-L gauge boson, ...
Doubly charged Higgsinos at LHC
(Proceedings of Science, 2008)
We review single and pair production and subsequent decay of doubly charged Higgsinos of the left-right supersymmetric model at the LHC. The novel signature is possible to separate from the MSSM and UED signal.
