We explored various cases for the branching ratios (BRs) of $B_s\to K^+K^-$, $B_s\to K^0\bar{K}^0$ and $B_d\to π^+ π^-$ decays. We
We study the $B^0_s-\bar{B^0_s}$ mixing amplitude in Standard Model by computing the relevant hadronic matrix element in the static limit
The rare decay B^+ \to D_s^+ \bar K^{*0} can occur only via annihilation diagrams in the Standard Model. We calculate
Provided the enhancement in the $p \bar{p}$ spectrum in radiative decay $J/ψ\to γp \bar{p}$ observed by the BES collaboration is
We show that there is a double counting in the standard model of $n\bar{n}$ mixing in the medium, resulting in
We present sensitive interferometric 12CO, 13CO and HCN observations of the barred spiral galaxy NGC7479, known to be one of
The most recent recalculation of the two-loop correction to the static quark-antiquark potential gave the numerical value different from the
In this talk I report on the results of a recent calculation of the α_s corrections to a three-point correlation
We explore the capability of the Tevatron and LHC as well as other future hadron colliders to place limits on
The radiative decay $\BSgamma$ and the mixing $\BsBs$ are discussed in the vector-like quark model which contains extra SU(2)-singlet quarks
The level classification of quark-antiquark systems is generally made by the LS-coupling scheme, resorting to the non-relativistic quark model. However,
Recently BES2 collaboration observed an enhancement near the $p\bar p$ invariant mass spectrum. Using the covariant tensor formalism, here we
The polarization asymmetries of $t$, $\bar t$ quarks can be used in the reaction $e^+e^-\to t\bar tν_e\barν_e$ to measure the
We present results of an investigation to study CP violation in the Higgs sector in $t\bar t$ production at a
This talk contains a summary of our work on dynamical CPT invariance and spontaneous CPT violation in string theories, including
Measurement results on $D^0$-$\bar D^0$ mixing and CP violation are presented. FOCUS, a fixed target experiment at Fermilab, collected a
The last few years witnessed a change of perspective in the context of galaxy formation and evolution. The major role
We calculate the decay constant of $D_s$ and $D_s^{*}$ with $\bar{B}^0 \ra D^{+}\ell^{-}ν$ and $\bar{B}^0 \ra D^{+}D_s^{-(*)}$ decays. In our

The branching fractions for $ψ(3770) \to D^0 \bar D^0, D^+D^-,D\bar D$ and $ψ(3770) \to {\rm non-}D\bar D$ are determined based
Due a mistake in identifying the operators $O_9$ and $O_{10}$ which leads to errorous expressions in eq. 9. With the
We present results on the determination of the observable ratio R=BR(H^+ -> τν)/BR(H^+ -> t b-bar) of charged Higgs boson
The invariant mass spectrum of the lepton pair in inclusive semileptonic $\bar B\to X_u \ell\barν$ decay yields a model independent
We study the properties of time evolution of the $K^{0}-\bar{K}^{0} $ system in spectral formulation. Within the one--pole model we
