【 摘 要 】

In minimal supergravity (mSUGRA) or CMSSM, one of the main co-annihilating partners of the neutralino is the lightest stau, $ilde{𝜏}_{1}$. In the presence of flavour violation in the right-handed sector, the co-annihilating partner would be a flavour mixed state. The flavour effect is two-fold:It changes the mass of $lide{𝜏}_{1}$, thus modifying the parameter space of the co-annihilation and
