Precise calculation of neutralino relic density in the minimal supergravity model
Takeshi Nihei
We study precise calculation of neutralino relic density in the minimal supergravity model. We compare the exact formula for the thermal average of the neutralino annihilation cros…

New constraint on the minimal SUSY GUT model from proton decay
Toru Goto, Takeshi Nihei
We present results of reanalysis on proton decay in the minimal SU(5) SUSY GUT model. Unlike previous analyses, we take into account a Higgsino dressing diagram of dimension 5 oper…
