Gauge mediated supersymmetry breaking and the cosmology of Left-Right symmetric model
, 2008 Left-Right symmetry including supersymmetry presents an important class of gauge models which may possess natural solutions to many issues of phenomenology. Cosmology of such models indicates a phase transition accompanied by domain walls.

Resonant Higgs pair production as a probe of stop at the LHC
Journal of High Energy Physics, 2017 Searching for top squark (stop) is a crucial task of the LHC. When the flavor conserving two body decays of the stop are kinematically forbidden, the stops produced near the threshold will live long enough to form bound states which subsequently decay ...

The current status of fine-tuning in supersymmetry
Journal of High Energy Physics, 2020 In this paper, we minimize and compare two different fine-tuning measures in four high-scale supersymmetric models that are embedded in the MSSM. In addition, we determine the impact of current and future dark matter direct detection and collider ...

Phenomenological constraints on broken supersymmetry
Physics Letters B, 1978 Abstract We show that the existence of massless color octet quarks, which appear in a class of broken supersymmetric field theories, implies the existence of additional light (⪅ 1 GeV) unstable hadrons with large (⪆ 10 μb) production cross sections. We estimate the half-life for these states to be less than 10−8 s. If it is greater than 10°10 s,

Supersymmetry Phenomenology: A Microreview
, 1995 We briefly review the current status and future prospects for supersymmetry searches at colliders, and discuss strategies by which further information about sparticle properties may be obtained at the LHC.

Tagging new physics with charm
Journal of High Energy Physics, 2017 We propose a new variable, the charm fraction, for collider searches for new physics. We analyze this variable in the context of searches for simplified supersymmetry models with squarks, the gluino, and the bino, assuming that only the lightest ...

Exploring the nearly degenerate stop region with sbottom decays
Journal of High Energy Physics, 2017 A light stop with mass almost degenerate with the lightest neutralino has important connections with both naturalness and dark matter relic abundance. This region is also very hard to probe at colliders.

Low Energy Supersymmetry From the Landscape
, 2004 There has been some debate as to whether the landscape does or does not predict low energy supersymmetry. We argue that under rather mild assumptions, the landscape seems to favor such breaking, quite possibly at a very low scale.

Soft Spectrum in Yukawa-Gauge Mediation
, 2012 We introduce a model independent parametrization for a subclass of gauge mediated theories, which we refer to as Yukawa-gauge mediation. Within this formalism we study the resulting soft masses in the visible spectrum. We find general expressions for the
