Supersymmetric Galilean Electrodynamics

Journal of High Energy Physics, 2022
In 2+1 dimensions, we propose a renormalizable non-linear sigma model action which describes the N $$ \mathcal{N} $$ = 2 supersymmetric generalization of Galilean Electrodynamics.

Inflation from Supersymmetry Breaking

Universe, 2019
I discuss the possibility that inflation is driven by supersymmetry breaking, with the superpartner of the goldstino (sgoldstino) playing the role of the inflaton. Imposing an R-symmetry to satisfy the slow-roll conditions, avoiding the so-called η

Lorentz Violation and Superpartner Masses

, 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.

CP Violation from Slepton Oscillations at the LHC and NLC [PDF]

, 1997
In supersymmetric theories the charged sleptons of different generations may oscillate amongst themselves while they decay. In the case of three generation oscillations, superpartner production at the LHC and NLC may lead to an observable $CP$-violating ...

Precision predictions for electroweak superpartner production at hadron colliders with Resummino

European Physical Journal C: Particles and Fields, 2013
We describe the Resummino package, a C++ and Fortran program dedicated to precision calculations in the framework of gaugino and slepton pair production at hadron colliders.

Fermion mass hierarchies from supersymmetric gauged flavour symmetry in 5D

SciPost Physics, 2021
A mechanism to generate realistic fermion mass hierarchies based on supersymmetric gauged $U(1)_F$ symmetry in flat five-dimensional (5D) spacetime is proposed. The fifth dimension is compactified on $S^1/Z_2$ orbifold.

Naturally heavy superpartners and a Little Higgs

, 2005
We construct an extension of the MSSM in which scalar superpartners can naturally be as heavy as 1 TeV. In the MSSM, the most significant fine tuning stems from the logarithmically enhanced top-stop loop contribution to the soft Higgs mass.

N=1 supersymmetric Proca–Stueckelberg mechanism for extra vector multiplet

Nuclear Physics B, 2014
We present a variant formulation of N=1 supersymmetric Proca–Stueckelberg mechanism for an arbitrary non-Abelian group in four dimensions. This formulation resembles our previous variant supersymmetric compensator mechanism in 4D.

Exploring compressed supersymmetry with same-sign top quarks at the Large Hadron Collider [PDF]

, 2008
In compressed supersymmetry, a light top squark naturally mediates efficient neutralino pair annihilation to govern the thermal relic abundance of dark matter.

Comparatively light extra Higgs states as signature of SUSY SO(10) GUTs with 3rd family Yukawa unification

Journal of High Energy Physics, 2020
We study 3rd family Yukawa unification in the context of supersymmetric (SUSY) SO (10) GUTs and SO(10)-motivated boundary conditions for the SUSY-breaking soft terms.
