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 ...

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.

Naturally heavy superpartners and a Little Higgs [PDF]
Journal of High Energy Physics, 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.

New constraints on superpartner masses [PDF]
Physics Letters B, 1996 We consider the Minimal Supersymmetric Standard Model (MSSM) without imposing relations on the superpartner masses that arise in grand unified theories. Given an arbitrary pattern of superpartner masses (consistent with experimental constraints), it may happen that the scalar potential is actually unstable, even though all scalar masses-squared are ...

Superpartners and future colliders [PDF]
AIP Conference Proceedings, 2000 This talk focuses on two aspects of the search for supersymmetry. First I argue that if the breaking of the electroweak symmetry is indeed explained by supersymmetry, then it is very likely that superpartners will be produced at Fermilab. Second, once superpartners are found we will move to the next stage where we need to learn the implications of how ...

CONTINUUM SUPERPARTNERS FROM SUPERSYMMETRIC UNPARTICLES [PDF]
International Journal of Modern Physics A, 2010 In an exact conformal theory there is no particle. The excitations have continuum spectra and are called "unparticles" by Georgi. We consider supersymmetric extensions of the Standard Model with approximate conformal sectors. The conformal symmetry is softly broken in the infrared which generates a gap. However, the spectrum can still have a continuum

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. The right-handed top quark is unified with the Higgs, the top Yukawa arises from the gaugino coupling.

Black hole superpartners and fixed scalars [PDF]
Physical Review D, 1997 Some bosonic solutions of supergravities admit Killing spinors of unbroken supersymmetry. The anti-Killing spinors of broken supersymmetry can be used to generate the superpartners of stringy black holes. This has a consequent feedback on the metric and the graviphoton.

Electric Dipole Moments in the Limit of Heavy Superpartners [PDF]
Physical Review Letters, 2002 Supersymmetric loop corrections induce potentially large CP-violating couplings of the Higgs bosons to nucleons and electrons that do not vanish in the limit of heavy superpartners. The Higgs-mediated CP-odd four-fermion operators are enhanced by tan^3 beta and induce electric dipole moments of heavy atoms which exceed the current experimental bounds ...
