The Superpartner Spectrum of Gaugino Mediation [PDF]

Physical Review D, 2000
We compute the superpartner masses in a class of models with gaugino mediation (or no-scale) boundary conditions at a scale between the GUT and Planck scales.

Lorentz Violation and Superpartner Masses [PDF]

Physical Review D, 2007
We consider Lorentz violation in supersymmetric extensions of the standard model. We perform a spurion analysis to show that, in the simplest natural constructions, the resulting supersymmetry-breaking masses are tiny.

Single superpartner production at Tevatron Run II [PDF]

The European Physical Journal C, 2000
We study the single productions of supersymmetric particles at Tevatron Run II which occur in the $2 \to 2-body$ processes involving R-parity violating couplings of type $\l'_{ijk} L_i Q_j D_k^c$.

Recognizing Superpartners at LEP [PDF]

Physics Letters B, 1997
There is a class of supersymmetric models which is well-motivated by hints of evidence for SUSY and consistent with all existing data. It is important to study the predictions of these models. They are characterized by M(N3) > M(C1) > M(snu) > M(N1) (where Ni and Ci are neutralino and chargino mass eigenstates), |mu| ~< M1 ~< M2 ~= M(Z),

Yukawa Unification and the Superpartner Mass Scale [PDF]

Journal of High Energy Physics, 2012
Naturalness in supersymmetry (SUSY) is under siege by increasingly stringent LHC constraints, but natural electroweak symmetry breaking still remains the most powerful motivation for superpartner masses within experimental reach.

Superpartner spectrum of minimal gaugino-gauge mediation [PDF]

Journal of High Energy Physics, 2010
We evaluate the sparticle mass spectrum in the minimal four-dimensional construction that interpolates between gaugino and ordinary gauge mediation at the weak scale.

Continuum superpartners from supersymmetric unparticles [PDF]

Physical Review D, 2009
We examine supersymmetric theories with approximately conformal sectors. Without an IR cutoff the theory has a continuum of modes, which are often referred to as "unparticles." Making use of the AdS/CFT correspondence we find that in the presence of a soft-wall, a gap in the spectrum can arise, separating the zero-modes from the continuum modes.

Axion cosmology with its scalar superpartner [PDF]

Physics Letters B, 1998
In supersymmetric theories, the Peccei-Quinn symmetry has a complex extension as a symmetry of the superpotential, so that the scalar potential always has an almost flat direction, the dilaton. We discuss how coherent oscillation of the dilaton affects axion cosmology.

LIGHT SUPERPARTNERS AT HADRON COLLIDERS [PDF]

International Journal of Modern Physics A, 2006
Uncertainties of the MSSM predictions are due to an unknown SUSY breaking mechanism. To reduce these uncertainties, one usually imposes constraints on the MSSM parameter space. Recently, two new constraints became available, both from astrophysics: WMAP precise measurement of the amount of the Dark Matter in the Universe and EGRET data on an excess in

Fluid super-dynamics from black hole superpartners [PDF]

Physics Letters B, 2011
Recently the Navier-Stokes equations have been derived from the duality with the black branes in AdS_5. The zero modes of black branes are reinterpreted as dynamical degrees of freedom of a conformal fluid on the boundary of AdS_5. Here, we derive the corrections to the Navier-Stokes equations due to fermionic zero modes of the black branes.
