Chasing higgsino dark matter at colliders in the neutrino fog era
Prudhvi N. Bhattiprolu, Stephen P. Martin, James D. Wells
Higgsinos can be the lightest supersymmetric particles, allowing for either a full or partial dark matter interpretation, with the correct thermal freeze-out abundance obtained for…
Three-loop corrections to the Fermi decay constant in the scheme
Stephen P. Martin
I present the leading 3-loop contributions to the Fermi decay constant in the Standard Model, using the tadpole-free pure scheme. The calculation is exact in t…
The curtain lowers on directly detectable higgsino dark matter
Stephen P. Martin
A higgsino could be some or all of the dark matter, with a mass bounded from above by about 1.1 TeV assuming a thermal freezeout density, and from below by collider searches. Direc…
Effective Kähler and auxiliary field potentials for chiral superfield models at three loops
Stephen P. Martin
I obtain the effective Kähler potential at three-loop order for a general renormalizable supersymmetric theory containing only chiral supermultiplets. The three-loop contribution i…
Implications of purity constraints on light higgsinos
Stephen P. Martin
The lightest supersymmetric particles could be higgsinos that have a small mixing with gauginos. If the lightest higgsino-like state makes up some or all of the dark matter with a…
Three-loop effective potential for softly broken supersymmetry
Stephen P. Martin
The effective potential has been previously calculated through three-loop order, in Landau gauge, for a general renormalizable theory using dimensional regularization. However, dim…
