    Sensitivity of High-Scale SUSY in Low Energy Hadronic FCNC

    Full text link
    We discuss the sensitivity of the high-scale SUSY at 1010-10001000 TeV in B0B^0, BsB_s, K0K^0 and DD meson systems together with the neutron EDM and the mercury EDM. In order to estimate the contribution of the squark flavor mixing to these FCNCs,we calculate the squark mass spectrum, which is consistent with the recent Higgs discovery. The SUSY contribution in Ο΅K\epsilon_K could be large, around 40% in the region of the SUSY scale 1010-100100 TeV. The neutron EDM and the mercury EDM are also sensitive to the SUSY contribution induced by the gluino-squark interaction. The predicted EDMs are roughly proportional to ∣ϡKSUSY∣|\epsilon_K^{\rm SUSY}|. If the SUSY contribution is the level of O(10%) for epsilon_K, the neutron EDM is expected to be discovered in the region of 10βˆ’2810^{-28}-10βˆ’2610^{-26}ecm. The mercury EDM also gives a strong constraint for the gluino-squark interaction. The SUSY contribution of Ξ”MD\Delta M_D is also discussed.Comment: 25 pages, 10 figures. arXiv admin note: substantial text overlap with arXiv:1404.052

    Linking Leptonic CP violation to Quark Unitarity Triangle

    Full text link
    We study the linking between the CP violating phase of the lepton sectors and the unitarity triangle of the B0 meson system. Antusch, King, Malinsky and Spinrath have shown that the quark mass matrices with the negligible 1-3 mixing give an interesting relation between the phase of the quark mixing matrices and CP violating measure phi_2(alpha). This approach is extended by considering the SO(10) GUT including the Pati-Salam symmetry, which links the Yukawa matrices of the quark sector to the one of the lepton sector. We discuss the relation of the CP violating phases between both quark and lepton sectors as well as the mixing angles. Then, the leptonic CP violating phase is predicted in terms of the angle of the unitarity triangle of the B0 meson system. The leptonic CP violating phase deltaPMNS is predicted in the region -74 to -89, which is the consistent with the recent T2K results. Our predicted phase is sensitive to phi_2(alpha) and phi_3(gamma). These predictions will be clearly tested in the future neutrino experiments as well as the Belle-II experiment.Comment: 14 pages, 8 figures, Some discussions and Appendix are adde
