QCD effects on direct detection of wino dark matter

J Hisano, K Ishiwata, N Nagata - Journal of High Energy Physics, 2015 - Springer
A bstract We complete the calculation of the wino-nucleon scattering cross section up to the

Higgsino dark matter in high-scale supersymmetry

N Nagata, S Shirai - Journal of high energy physics, 2015 - Springer
A bstract We study a supersymmetric (SUSY) Standard Model in which a Higgsino is light
enough to be dark matter, while the other SUSY particles are much heavier than the weak …
