Low scale Seesaw model and Lepton Flavor Violating Rare B Decays

T. Fujihara, S. K. Kang, C. S. Kim +2

We study lepton flavor number violating rare B decays, $b \to s l_{h}^{\pm} l_{l}^{\mp}$ , in a seesaw model with low scale singlet Majorana neutrinos motivated by the resonant leptogen…

Supersymmetry Parameter Analysis: SPA Convention and Project

J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122

High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…

Quark-Lepton Complementarity with Renormalization Effects through Threshold Corrections

Sin Kyu Kang, C. S. Kim, Jake Lee

The recent experimental measurements of the solar neutrino mixing angle $θ_{so l}$ and the Cabibbo mixing angle $θ_{C}$ reveal a surprising relation, $θ_{so l} + θ_{C} ≃ \frac{π}{4}$ .…

QCD sum rules for the anti-charmed pentaquark

Yasemin Sarac, Hungchong Kim, Su Houng Lee

We present a QCD sum rule analysis for the anti-charmed pentaquark state with and without strangeness. While the sum rules for most of the currents are either non-convergent or dom…

Anti-charmed pentaquark from B decays

Su Houng Lee, Youngshin Kwon, Youngjoon Kwon

We explore the possibility of observing the anti-charmed pentaquark state from the $Θ_{c} n ˉ π^{+}$ decay of $B$ meson produced at $B$ -factory experiments. We first show that the…

Are deviation from bi-maximal mixing and none-zero U_{e3} related to non-degeneracy of heavy Majorana neutrinos?

Sin Kyu Kang, C. S. Kim

We propose a scenario that the mass splitting between the first generation of the heavy Majorana neutrino and the other two generations of degenerate heavy neutrinos in the seesaw…

Hierarchical Mass Structure of Fermions in Warped Extra Dimension

Sanghyeon Chang, C. S. Kim, Masahiro Yamaguchi

The warped bulk standard model has been studied in the Randall-Sundrum background on $S^{1} / Z \times Z^{'}$ interval with the bulk gauge symmetry $SU(3)\times SU(2)_L\times SU(2)_R\time…

Supersymmetric Contributions to Bs->K+K-

Seungwon Baek, David London, Joaquim Matias +1

Inspired by the existing calculation of B->piK decays in supersymmetry (SUSY), we evaluate the dominant SUSY contributions to Bs->K+K-. We show that the observables of this process…

The $B \to K π$ Puzzle and Supersymmetric Models

Richard Arnowitt, Bhaskar Dutta, Bo Hu +1

In the light of new experimental results on $B \to K π$ decays, we study the decay processes $B \to K π$ in the framework of both R-parity conserving (SUGRA) and R-parity violating…

Probing the radion-Higgs mixing at photon colliders

Kingman Cheung, C. S. Kim, Jeonghyeon Song

In the Randall-Sundrum model, the radion-Higgs mixing is weakly suppressed by the effective electroweak scale. A novel feature of the gravity-scalar mixing would be a sizable three…

Systematic Investigation of Possibilities for New Physics Effects in b --> s Penguin Processes

C. S. Kim, Y. J. Kwon, Jake Lee +1

Although recent experimental results in b-->s penguin process seem to be roughly consistent with the standard model predictions, there may be still large possibilities of new physi…

Non-interacting KN contribution in the QCD sum rule for the pentaquark Theta^+(1540)

Youngshin Kwon, Atsushi Hosaka, Su Houng Lee

We perform a QCD sum rule analysis for the pentaquark baryon Theta^+ with the non-interacting $K N$ contribution treated carefully. The coupling of the Theta^+ current to the $K N$ s…

Is $D_{s J}^{+} (2632)$ the first radial excitation of $D_{s}^{*} (2112)$ ?

Chao-Hsi Chang, C. S. Kim, Guo-Li Wang

We present a quantitative analysis of the $D_{s J}^{+} (2632)$ observed by SELEX mainly focusing on the assumption that $D_{s J}^{+} (2632)$ is the first radial excitation of the $1^{-…

A Critical Study of the B -> K πPuzzle

C. S. Kim, Sechul Oh, Chaehyun Yu

In the light of new experimental results on B -> K pi decays, we critically study the decay processes B -> K pi in a phenomenological way. Using the quark diagram approach and the…

The intrinsic and oscillated astrophysical neutrino flavor ratios

H. Athar, C. S. Kim, Jake Lee

The pp interactions taking place in the cosmos around us are a source of the astrophysical neutrinos of all the three flavors. In these interactions, the electron and the muon neut…

Muonium-antimuonium conversion in models with heavy neutrinos

Gorazd Cvetic, Claudio O. Dib, C. S. Kim +1

We study muonium-antimuonium conversion and mu+ e- to mu- e+ scattering within two different lepton-flavor-violating models with heavy neutrinos: model I is a typical seesaw that v…

Kaluza-Klein masses of bulk fields with general boundary conditions in AdS $_{5}$

Sanghyeon Chang, Seong Chan Park, Jeonghyeon Song

Recently bulk Randall-Sundrum theories with the gauge group $S U (2)_{L} \times S U (2)_{R} \times U (1)_{B - L}$ have drawn a lot of interest as an alternative to electroweak symmetry breaki…
