What next for the CMSSM and the NUHM: improved prospects for superpartner and dark matter detection [PDF]
, 2014 A bstractWe present an updated analysis of the CMSSM and the NUHM using the latest experimental data and numerical tools. We map out favored regions of Bayesian posterior probability in light of data from the LHC, flavor observables, the relic density ...

Predicting the superpartner spectrum from partially composite supersymmetry [PDF]
Physical Review D, 2019 We use the idea of partial compositeness in a minimal supersymmetric model to relate the fermion and sfermion masses. By assuming that the Higgs and third-generation matter is (mostly) elementary, while the first- and second-generation matter is (mostly)

Superpartner States in Quantum Mechanics of Colored Particle [PDF]
arXiv, 2003 Superpartner correspondence of states of colored particle in external chromomagnetic field given by non-commuting constant vector potentials is determined. Squared Dirac equation for this particle is solved exactly and explicit expressions of superpartner states are found. The wave functions of states with definite energy are found.

AbelianDterms 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 ...

New constraints on superpartner masses [PDF]
Physics Letters B, 1995 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 ...

A global fit of LEP/SLC data with light superpartners [PDF]
Physics Letters B, 1995 We find that re-analyzing the LEP/SLC data with light superpartners and low $ _s(\mz^2)\simeq 0.112$ yields a better fit to the data than the Standard Model, giving a satisfactory description of the $R_b$ measurement, and a better fit to $A_{LR}$. A large body of low energy ($q^2 \ll \mz^2$) data and analyses provide compelling evidence for $ _s(\mz ...

Precision superpartner spectroscopy in the inclusive same-sign dilepton channel at the LHC [PDF]
, 2010 The inclusive same-sign dilepton channel is already recognized as a promising discovery signature for supersymmetry in the early days of the LHC. We point out that it can also be used for precision measurements of sparticle masses after the initial ...

Fingerprints of supersymmetric spin and charge dynamics observed by inelastic neutron scattering [PDF]
Nature CommunicationsSupersymmetry is an algebraic property of a quantum Hamiltonian that, by giving every boson a fermionic superpartner and vice versa, may underpin physics beyond the Standard Model. Fractional bosonic and fermionic quasiparticles are familiar in condensed

A microscopic model for inflation from supersymmetry breaking [PDF]
European Physical Journal C: Particles and Fields, 2019 We have proposed recently a framework for inflation driven by supersymmetry breaking with the inflaton being a superpartner of the goldstino, that avoids the main problems of supergravity inflation, allowing for: naturally small slow-roll parameters ...
