Exploring compressed supersymmetry with same-sign top quarks at the Large Hadron Collider
Stephen P. Martin
In compressed supersymmetry, a light top squark naturally mediates efficient neutralino pair annihilation to govern the thermal relic abundance of dark matter. I study the LHC sign…
Diphoton decays of stoponium at the Large Hadron Collider
Stephen P. Martin
If the lighter top squark has no kinematically allowed two-body decays that conserve flavor, then it will form hadronic bound states. This is required in models that are motivated…
Cosmic Strings from Supersymmetric Flat Directions
Yanou Cui, Stephen P. Martin, David E. Morrissey +1
Flat directions are a generic feature of the scalar potential in supersymmetric gauge field theories. They can arise, for example, from D-terms associated with an extra abelian gau…
The top squark-mediated annihilation scenario and direct detection of dark matter in compressed supersymmetry
Stephen P. Martin
Top squark-mediated annihilation of bino-like neutralinos to top-antitop pairs can play the dominant role in obtaining a thermal relic dark matter abundance in agreement with obser…
Compressed supersymmetry and natural neutralino dark matter from top squark-mediated annihilation to top quarks
Stephen P. Martin
The parameters of the Minimal Supersymmetric Standard Model appear to require uncomfortably precise adjustment in order to reconcile the electroweak symmetry breaking scale with th…
Three-loop corrections to the lightest Higgs scalar boson mass in supersymmetry
Stephen P. Martin
I evaluate the largest three-loop corrections to the mass of the lightest Higgs scalar boson in the Minimal Supersymmetric Standard Model in a mass-independent renormalization sche…
