Possible astrophysical signatures of heavy stable neutral relics in supergravity models [PDF]

, 2001
We consider heavy stable neutral particles in the context of supergravity and show that a gravitationally suppressed inflaton decay can produce such particles in cosmologically interesting abundances within a wide mass range $10^3 {\rm GeV} \leq m_X \leq

The supersymmetric Higgs for heavy superpartners

Physics Letters B, 1991
Abstract In a general softly broken supersymmetric theory with Higgs doublets only, we calculate the radiative corrections to the mass of the lightest neutral Higgs boson in the particular case where all the extra particles introduced by supersymmetry are close in mass and all heavier than the Fermi scale.

τ̃ searches at future e+e− colliders [PDF]

EPJ Web of Conferences
The direct pair-production of the superpartner of the τ-lepton, the τ̃, is one of the most interesting channels to search for SUSY in: the τ̃ is likely to be the lightest of the scalar leptons, and is one of the most experimentally chalanging ones.

How to look for supersymmetry under the lamppost at the LHC

, 2010
We apply a model-independent, agnostic approach to the collider phenomenology of supersymmetry (SUSY), in which all mass parameters are taken as free inputs at the weak scale. We consider the gauginos, higgsinos, and the first two generations of sleptons

Minimal R+R2 supergravity models of inflation coupled to matter

Physics Letters B, 2014
The supersymmetric extension of “Starobinsky” R+αR2 models of inflation is particularly simple in the “new minimal” formalism of supergravity, where the inflaton has no scalar superpartners.

Precision Supersymmetry Measurements at the e^-e^- Collider [PDF]

, 1998
Measurements of supersymmetric particle couplings provide important verification of supersymmetry. If some of the superpartners are at the multi-TeV scale, they will escape direct detection at planned future colliders.

Resonant slepton production and right sneutrino dark matter in left-right supersymmetry

Journal of High Energy Physics, 2017
Right-handed sneutrinos are natural components of left-right symmetric supersymmetric models where the gauge sector is extended to include right-handed weak interactions.

Supersymmetry and eigensurface topology of the spherical quantum pendulum [PDF]

, 2015
We undertook a mutually complementary analytic and computational study of the full-fledged spherical (3D) quantum rotor subject to combined orienting and aligning interactions characterized, respectively, by dimensionless parameters $\eta$ and $\zeta ...

Minimal Supergravity with m_0^2 < 0

, 2005
We extend the parameter space of minimal supergravity to negative values of m_0^2, the universal scalar mass parameter defined at the grand unified scale.

Bounds on Supersymmetry from Electroweak Precision Analysis [PDF]

, 1998
The Standard Model global fit to precision data is excellent. The Minimal Supersymmetric Standard Model can also fit the data well, though not as well as the Standard Model.
