Dr Li Run-Hui (Yonsei Univ.)20/02/2012, 19:20We analyze the $B\to K_2^*(\to K\pi)l^+l^-$ (with $l=e,\mu,\tau$) decay in the standard model and two new physics scenarios: vector-like quark model and family non-universal $Z'$ model. We derive its differential angular distributions, using the recently calculated form factors in the perturbative QCD approach. Branching ratios, polarizations, forward-backward asymmetries and transversity...Go to contribution page

Dr Fanrong Xu (National Taiwan U.)20/02/2012, 19:40We show that simultaneout precision measurements of the CP-violating phase in time-dependent B_{s} --> J/ψφ study and the B_{s} --> μ+μ- rate, together with measuring m_{t`} by direct search at the LHC, would determine V_{t`b}V*_{t`s} and therefore the quadrangle in the four-generation standard model. The forward-backward asymmetry in B --> K*μ+μ- provides further discrimination.Go to contribution page

Dr Jae-hyeon Park (IKTP, TU Dresden)20/02/2012, 20:00Due to the smallness of the lepton Yukawa couplings, higher-dimensional operators can give a significant contribution to the lepton masses. In this case, the lepton mass matrix and the matrix of lepton-Higgs couplings are misaligned leading to lepton flavor violation (LFV) mediated by the Standard Model Higgs boson. We derive model-independent bounds on the Higgs flavor violating couplings...Go to contribution page

Kei Yamamoto (Niigata Univ.)20/02/2012, 20:40The like-sign dimuon charge asymmetry observed by the D$\O$ Collaboration indicates the CP violating contribution from new physics in the $B_s$ meson mixing. Recently, the LHCb reported the observed CP-violating asymmetry in $B_s^0\to J/\psi \phi$ and $B_s^0\to J/\psi f_0(980) $, which is consistent with the SM prediction. However, there is still possible contribution on the CP violating new...Go to contribution page

Dr Yeo Woong Yoon (KIAS)20/02/2012, 21:00We compute the pole mass of the gluino in the minimal gauge mediation to two-loop order. The pole mass of the gluino begins to arise at one-loop order and the two-loop order correction shifts the leading order pole mass by 20% or even more. This shift is much larger than the expected accuracy of the mass determination at the LHC, and should be reckoned with for precision studies on the SUSY...Go to contribution page

Dr Gaber Faisel (National Central U.)20/02/2012, 21:20We discuss the dynamical mass generation resulting from supersymmetric extensions of the classical Nambu-Jona-Lasinio model namely from interaction terms with four chiral superfields. The kind of interactions maybe considered a supersymmetric generalization of the four-fermion interactions of the classic Nambu-Jona-Lasinio model. We illustrate the dynamical generation of superfield...Go to contribution page
