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]
, 2009 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 ...

750 GeV Diphoton Excess from the Goldstino Superpartner. [PDF]
Physical Review Letters, 2015 We interpret the diphoton excess recently reported by the ATLAS and CMS Collaborations as a new resonance arising from the sgoldstino scalar, which is the superpartner of the Goldstone mode of spontaneous supersymmetry breaking, the goldstino.

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 ...

GUT scale and superpartner masses from anomaly mediated supersymmetry breaking [PDF]
, 2000 We consider models of anomaly-mediated supersymmetry breaking (AMSB) in which the grand unification (GUT) scale is determined by the vacuum expectation value of a chiral superfield.

Solitonic ground state in supersymmetric theory in background [PDF]
Journal of High Energy PhysicsA solitonic ground state called a chiral soliton lattice (CSL) is realized in a supersymmetric theory with background magnetic field and finite chemical potential.

Long-living superpartners in the MSSM
, 2007 The parameter space of the Constrained Minimal supersymmetric Standard Model is considered. It is shown that for the particular choice of parameters there are some regions where long-living charged superparticles exist. Two regions of interest are the co-annihilation region with light staus, and the region with large negative trilinear scalar coupling ...
