Charge and CP asymmetries of meson in unparticle physics

Chuan-Hung Chen, C. S. Kim, Run-Hui Li

Recently the DØ Collaboration reported an observation of like-sign charge asymmetry (CA), which is about deviation from the standard model (SM) prediction. Inspired by the…

Charmonium mass in hot and dense hadronic matter

Kenji Morita, Su Houng Lee

We investigate mass shifts of charmonia driven by change of the gluon condensate below but near transition temperatures at finite baryonic chemical potential. Extending previous pr…

Quark Number Susceptibility with Finite Quark Mass in Holographic QCD

Kyung-il Kim, Youngman Kim, Shingo Takeuchi +1

We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D…

A like-sign dimuon charge asymmetry at Tevatron induced by the anomalous top quark couplings

Jong Phil Lee, Kang Young Lee

We show that the recently measured 3.2 deviations of the charge asymmetry of like-sign dimuon events from the standard model prediction by the D0 collaboration at Tevatron can…

Forward-backward asymmetry of top quark in unparticle physics

Chuan-Hung Chen, G. Cvetic, C. S. Kim

The updated CDF measurement of the forward-backward asymmetry (FBA) in the top quark production p{bar p} -> t{bar t} at Tevatron (with the CMS energy 1.96 TeV) shows a deviation of…

Unparticle contributions to $\Bs$-$\Bsbar$ mixing

Jong-Phil Lee

The unparticle effects on the $\Bs$-$\Bsbar$ mixing is revisited. Taking into account the unitarity constraints on the unparticle operators, we find that the contribution of the ve…

production and elliptic flow in relativistic heavy-ion collisions

Taesoo Song, Che Ming Ko, Su Houng Lee +1

Using a two-component model for charmonium production, which includes contributions from both the initial hard nucleon-nucleon scattering and from the regeneration in the quark-glu…

The B ---> π K puzzle and the Bulk Randall-Sundurm model

Sanghyeon Chang, C. S. Kim, Jeonghyeon Song

The recent measurements of the direct CP asymmetries () in the penguin-dominated decays show some discrepancy from the standard model (SM) prediction. While $A_{…

Probing Majorana neutrinos in rare K and D, D_s, B, B_c meson decays

G. Cvetic, Claudio Dib, Sin Kyu Kang +1

We study lepton number violating decays of charged K, D, D_s, B and B_c mesons of the form M^+\to {M'}^-\ell^+\ell^+, induced by the existence of Majorana neutrinos. These processe…

A direct link between neutrinoless double beta decay and leptogenesis in a seesaw model with symmetry

Y. H. Ahn, Sin Kyu Kang, C. S. Kim +1

We study how leptogenesis can be implemented in a seesaw model with flavor symmetry, which leads to the neutrino tri-bimaximal mixing matrix and degenerate right-handed (RH)…

Testing the Non-universal Z^\prime Model in Bs -> ϕπ^0 Decay

Juan Hua, C. s Kim, Ying Li

The branching ratio and direct CP asymmetry of the decay mode have been calculated within the QCD factorization approach in both the standard model (SM) and the non-…

Annihilation-Type Charmless Radiative Decays of B Meson in Non-universal Z^\prime Model

Juan Hua, C. s Kim, Ying Li

We study charmless pure annihilation type radiative B decays within the QCD factorization approach. After adding the vertex corrections to the naive factorization approach, we find…

Su Houng Lee, A. Ozpineci, Y. Sarac

For the heavy baryons and the coupling constants and are calculated in the framework of light cone QCD sum rules. The most general form of t…
