Little Higgs model with new Z-parity and Dark matter

C. S. Kim, Jubin Park

It has been known that Little Higgs models with T-parity, which can give a dark matter candidate, suffer from the anomalies of given models through the Wess-Zumino-Witten term, whi…

New Charmonium States in QCD Sum Rules: a Concise Review

Marina Nielsen, Fernando S. Navarra, Su Houng Lee

In the past years there has been a revival of hadron spectroscopy. Many interesting new hadron states were discovered experimentally, some of which do not fit easily into the quark…

Invisible Higgs decay with B\to Kν\barν constraint

C. S. Kim, Seong Chan Park, Kai Wang +1

If the Higgs boson were the only particle within the LHC accessible range, precision measurement of the Higgs's properties would play a unique role in studying electroweak symmetry…

Dark matter signals and cosmic ray anomalies in an extended seesaw model

H. S. Cheon, Sin Kyu Kang, C. S. Kim

An extended seesaw model proposed to achieve low scale leptogenesis can resolve the excess positron and electron fluxes observed from PAMELA, ATIC and/or Fermi-LAT, and simultaneou…

Sommerfeld Enhancement from Unparticle Exchange for Dark Matter Annihilation

Chuan-Hung Chen, C. S. Kim

We investigate the implication of unparticle exchange for the possible Sommerfeld enhancement in dark matter annihilation process. Assuming the unparticle exchange during WIMP coll…

Heavy quarkonium correlators at finite temperature: QCD sum rule approach

Kenji Morita, Su Houng Lee

We investigate the properties of heavy quarkonia at finite temperature in detail using QCD sum rules. Extending previous analyses, we take into account a temperature dependent effe…

Studying Exclusive Semi-leptonic Decays in the MSSM without R-parity

C. S. Kim, Ru-Min Wang

We present a complete study of R-parity violating supersymmetric effects in thirteen exclusive and inclusive semi-leptonic decays, including $B^+_u\to K^{(*)+}…

Effects of Flavor Dependence on Weak Decays of J/psi and Υ

Rohit Dhir, R. C. Verma, Avinash Sharma

We give the detailed analysis of effects of flavor dependence of average transverse quark momentum inside a meson on J/psi --> P and Υ--> Bc transition form factors and two-body we…

B_s\to K^{(*)-}K^{(*)+}, K^{(*)-}π^{+}, K^{(*)-}ρ^{+} decays in R-parity violating supersymmetry

Yuan-Guo Xu, Ru-Min Wang, Ya-Dong Yang

With the first measurements of the branching ratios and the direct CP asymmetries of , decays by the CDF collaboration, we constrain the relevant pa…

Stable multiquark states with heavy quarks in a diquark model

Su Houng Lee, Shigehiro Yasui

Based on the color-spin interaction in diquarks, we argue why some multiquark configurations could be stable against strong decay when heavy quarks are included. After showing the…
