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.

A Spin-1 Top Quark Superpartner [PDF]
Physical Review Letters, 2008 We construct a supersymmetric model where the left-handed top and bottom quarks are mainly the gauginos of a vector supermultiplet and hence their superpartners are spin-1.

Electroweak superpartner production at 13.6 Tev with Resummino
European Physical Journal C: Particles and Fields, 2023 Due to the greater experimental precision expected from the currently ongoing LHC Run 3, equally accurate theoretical predictions are essential. We update the documentation of the Resummino package, a program dedicated to precision cross section ...

Constraints from Inflation and Reheating on Superpartner Masses [PDF]
Physics Letters B, 1996 Flat directions in the Minimal Supersymmetric Standard Model (MSSM) can become unstable due to radiative corrections, and the global minimum of the (zero temperature) potential can lie at large values of the squark and/or slepton fields.

Superpartner mass measurements with 1D decomposed MT2 [PDF]
, 2010 We propose a new model-independent technique for mass measurements in missing energy events at hadron colliders. We illustrate our method with the most challenging case of a short, single-step decay chain.

Natural Gauge and Gravitational Coupling Unification and the Superpartner Masses [PDF]
Physics Letters B, 2006 The possibility to achieve unification at the string scale in the context of the simplest supersymmetric grand unified theory is investigated. We find conservative upper bounds on the superpartner masses consistent with the unification of gauge and ...

Supersymmetry Laser Arrays with High‐Order Exceptional Point
Advanced Photonics Research, 2023 Supersymmetry (SUSY) laser array with superpartner structure can suppress excess modes to achieve high‐intensity and high‐coherent radiation. Compared with complex superpartner, using parity time (PT) symmetry broken to manipulate SUSY laser arrays is a ...

Exploring the flavour structure of the high-scale MSSM [PDF]
European Physical Journal C: Particles and Fields, 2020 We analyse the sensitivity of quark flavour-changing observables to the MSSM, in a regime of heavy superpartners. We analyse four distinct and motivated frameworks characterising the structure of the soft-breaking terms by means of approximate flavour ...

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 ...
