New Anomalous Exchange in Regge Phenomenology and Hard Diffraction

N. I. Kochelev, D. -P. Min, Y. Oh +2

A new mechanism for hard diffraction based on the anomalous $f_{1}$ trajectory exchange, which we identify as the odd signature partner of the Pomeron, is suggested. We calculate the…

Proper construction of the continuum in light-cone QCD sum rules

Hungchong Kim, Su Houng Lee, Makoto Oka

A proper way of subtracting the continuum contributions in light-cone QCD sum rules (LCQSR) is demonstrated. Specifically, we calculate the continuum corresponding to a typical OPE…

Measurement of |V_{ub}/V_{cb}| (and |V_{ub}|) in Exclusive Nonleptonic Decays, \bar{B}^0 --> D_s^{()-}(π^+,ρ^+) and \bar{B}^0 --> D_s^{()-}D^{(*)+}

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

We have studied extracting $|\vub/\vcb|$ by calculating the ratios $B (B ˉ^{0} \to D_{s}^{(*) -} (π^{+}, ρ^{+})) / B (B ˉ^{0} \to D_{s}^{(*) -} D^{(*) +})$ including penguin effects…

Enhancement of the Higgs pair production at LHC; the MSSM and extra dimension effects

C. S. Kim, Kang Young Lee, Jeonghyeon Song

The neutral Higgs pair production at the LHC is studied in the MSSM, the large extra dimensional (ADD) model and the Randall-Sundrum (RS) model, where the total cross section can b…

Determination of the CP violating weak phase $γ$ from the Decays $B \to D π$

C. S. Kim, Sechul Oh

We propose a new method to extract the CP violating weak phase $γ$ (the phase of $V_{u b}^{*}$ ) in the CKM paradigm of the Standard Model, using $B^- \rightarrow D^0 π^- \rightarrow f…

Hadronic Invariant Mass Spectrum in B -> X_u l nu Decay with Lepton Energy Cut

K. K. Jeong, C. S. Kim, Yeong Gyun Kim

We discuss the implications of charged lepton energy cut to the hadronic invariant mass spectrum in charmless semileptonic B decays. Charged-lepton energy cut is inevitable in orde…

No CPT Violation from Tilted Brane in Neutral Meson--Antimeson Systems

G. Cvetic, S. K. Kang, C. S. Kim +1

Tilted brane in theories with large compact extra dimensions leads to spontaneous symmetry breaking of the Lorentz and rotational invariance in four dimensions, as shown by Dvali a…

Is Cabibbo-Kobayasi-Maskawa Matrix Unitary?

C. S. Kim, H. Yamamoto

First, we give summary of the present values of CKM matrix elements. Then, we discuss whether CKM matrix is unitary or not, and how we can find out if it is not unitary.

The CKM phase $α$ through $B \to a_{0} π$

Amol S. Dighe, C. S. Kim

We propose the decay modes $B \to a_{0} (\to η π) π$ to determine the CKM phase $α$ . One can analyze these modes through (i) the $B \to a_{0} π$ isospin pentagon, (ii) the time dependen…

Sin Kyu Kang, C. S. Kim, J. D. Kim

Neutrino oscillations as solutions of the solar neutrino problems and the atmospheric neutrino deficits may restrict neutrino mass squared differences and mixing angles in three-ne…

The Effects of Non-Local Interactions in Rare B Decays, B -> X_s l^+l^-

S. Fukae, C. S. Kim, T. Yoshikawa

The effects of non-local interactions in rare B decays, $\Bsll$, are investigated. We show the correlation between the branching ratio and the forward-backward asymmetry via two co…

Azimuthal Angle Distribution in $B \to K^{*} (\to K π) ℓ^{+} ℓ^{-}$ at low invariant $m_{ℓ^{+} ℓ^{-}}$ Region

C. S. Kim, Yeong Gyun Kim, Cai-Dian Lu +1

We present the angular distribution of the rare B decay, $B \to K^{*} (\to K π) ℓ^{+} ℓ^{-}$ . By studying the azimuthal angle distribution in the low invariant mass region of dilep…
