Bs-->K+K- and Bs-->K0 anti-K0 Decays within Supersymmetry
Seungwon Baek, David London, Joaquim Matias +1
We compute the supersymmetric (SUSY) contributions to the observables in Bs-->K+K- and Bs-->K0 anti-K0 decays. The hadronic parameters in the standard-model (SM) amplitudes are obt…
Electroweak Penguin and Leptophobic model
S. Baek, J. H. Jeon, C. S. Kim +1
We consider the leptophobic model which can appear naturally in the flipped SU(5) or string-inspired models. This model can be constrained by measurements of the $…
Symmetry and Radiatively Generated Leptogenesis
Y. H. Ahn, Sin Kyu Kang, C. S. Kim +1
We consider a symmetry in neutrino sectors realized at GUT scale in the context of a seesaw model. In our scenario, the exact symmetry realized in the basis where the c…
Associated production of a single heavy T-quark in the littlest and simplest little Higgs models
Kingman Cheung, C. S. Kim, Kang Young Lee +1
The colored SU(2)-singlet heavy T-quark is one of the most crucial ingredients in little Higgs models, which is introduced to cancel the largest contribution of the SM top quark to…
B_s^0 - \bar{B}_s^0 Mixing in Leptophobic Z^\prime Model
Seungwon Baek, Jong Hun Jeon, C. S. Kim
Leptophobic Z^\prime gauge boson appears naturally in many grand unified theories, such as flipped SU(5) or string-inspired E_6 models. This elusive particle easily escapes the dir…
Lepton flavor violation in muonium decay and muon colliders in models with heavy neutrinos
Gorazd Cvetic, Claudio O. Dib, Choong-Sun Kim +1
We study the lepton-flavor-violating reaction within two extensions of the standard model that include heavy neutrinos. The reaction is studied in the low ene…
Constraint of B_{d,s}-bar{B}_{d,s} mixing on warped extra-dimension model
Sanghyeon Chang, C. S. Kim, Jeonghyeon Song
Recent CDF measurement of the Bs-Bs oscillation frequency, at the Tevatron imposes significant constraint on various models for new physics. A warped extra-dimension model with cus…
Extended double seesaw model for neutrino mass spectrum and low scale leptogenesis
Sin Kyu Kang, C. S. Kim
We consider a variant of seesaw mechanism by introducing extra singlet neutrinos, with which we show how the low scale leptogenesis is realized without imposing the tiny mass split…
Mixing and Its Implication for Transitions in Supersymmetry
Richard Arnowitt, Bhaskar Dutta, Bo Hu +1
We investigate the effect of the current measurement of the neutral meson mass difference, , on SUGRA models which have non-zero values of the soft breaking terms $…
New physics in and decays
Seungwon Baek
We perform a combined analysis of and decays with the current experimental data. Assuming SU(3) flavor symmetry and no new physics contributions to the topolo…
B_s - \bar{B}_s mixing in the MSSM scenario with large flavor mixing in the LL/RR sector
Seungwon Baek
We show that the recent measurements of mass difference, , by DØ and CDF collaborations give very strong constraints on MSSM scenario with large flavor mixing…
Phased Breaking of mu-tau symmetry and Leptogenesis
Y. H. Ahn, Sin Kyu Kang, C. S. Kim +1
Non-vanishing U_{e3} has been theoretically related to a certain flavor symmetry breaking in the neutrino sector. We propose a scenario to break the mu-tau symmetry so as to accomm…
Exclusive B-> M ν\barν (M= π, K, ρ, K^*) Decays and Leptophobic Z^\prime Model
Jong Hun Jeon, C. S. Kim, Jake Lee +1
We consider the exclusive flavor changing neutral current processes B -> M ν\barν (M= π, K, ρ, K^*) in the leptophobic Z^\prime model, in which the charged leptons do not couple to…
