Massive Spinning Relativistic Particle: Revisited under BRST and Supervariable Approaches
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 We discuss the continuous and infinitesimal gauge, supergauge, reparameterization, nilpotent Becchi‐Rouet‐Stora‐Tyutin (BRST), and anti‐BRST symmetries and derive corresponding nilpotent charges for the one (0 + 1)‐dimensional (1D) massive model of a spinning relativistic particle.

Abelian D-terms and the superpartner spectrum of anomaly-mediated supersymmetry breaking [PDF]
, 2003 We address the tachyonic slepton problem of anomaly mediated supersymmetry breaking using abelian D-terms. We demonstrate that the most general extra U(1) symmetry that does not disrupt gauge coupling unification has a large set of possible charges that ...

$$\alpha $$ α -attractors from supersymmetry breaking
European Physical Journal C: Particles and Fields, 2021 We construct new models of inflation and spontaneous supersymmetry breaking in de Sitter vacuum, with a single chiral superfield, where inflaton is the superpartner of the goldstino.

Higgs and Z-boson Signatures of Supersymmetry [PDF]
, 1999 In supersymmetric theories of nature the Higgsino fermionic superpartner of the Higgs boson can arise as the lightest standard model superpartner depending on the couplings between the Higgs and supersymmetry breaking sectors.

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.

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 ...

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

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.

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.
