| dc.description | 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 operator with right-handed matter fields ($RRRR$ operator). It is shown that this diagram gives a significant contribution for $p \to K^{+}\barν_τ$. Constraints on the colored Higgs mass $M_C$ and the sfermion mass $m_{\tilde{f}}$ from Super-Kamiokande limit become considerably stronger than those in the previous analyses: $M_C > 6.5\times 10^{16} \gev$ for $m_{\tilde{f}} < 1 \tev$. The minimal model with $m_{\tilde{f}} \lsim 2 \tev$ is excluded if we require the validity of this model up to the Planck scale. | |
