Test of CPT symmetry in cascade decays
Abstract. Cascade mixing provides an place for elegant study of $B^0$–$\bar{B^0}$ mixing. We use this idea to study the CPT violation caused by $B^0$–$\bar{B^0}$ mixing. An approximation method is adopted to treat the two complex $B^0$–$\bar{B^0}$ mixing parameters $\theta$ and $\phi$. A procedure to extract the parameters $\theta$ and $\phi$ is suggested. The feasibility of exploring CPT violation and determining $\theta$ and $\phi$ in the future B-factories and LHC-B is discussed.

Constraints on unparticle interactions from particle and antiparticle oscillations
AbstractUnparticles have dramatic effects on particle and antiparticle oscillations in meson–antimeson and muonium–antimuonium systems. Unlike the usual tree-level contributions to meson oscillations from heavy-particle exchange, which results in a small Γ12, the unparticle may have sizeable contributions to both M12 and Γ12 due to the fractional dimension 
$d_{\mathcal{U}}$ 
of the unparticle. If the unparticle effect dominates the contributions (which may happen in D0–
$\bar{D}^{0}$ 
mixing) to the meson mixing parameters x and y, we find that 
$x/y=\cot(\pi d_{\mathcal{U}})$
. The mass difference Δm in meson mixing can provide interesting constraints on the unparticle interactions. The unparticle interaction can significantly enhance the CP asymmetry in meson mixing, which can be tested in more accurate experiments in the future. Interesting constraints on unparticle and particle interactions can also be obtained using muonion and antimuonion oscillation data.

Phenomenological study of Sudakov effects in the pion form factor
The pion electromagnetic form factor with leading and next-to-leading twist corrections is studied in the framework of the pQCD approach. We find that the Sudakov effects provide a weak suppression of the nonperturbative contributions at the experimental accessible energy region. We also find a large twist-3 contribution. Our conclusion is that the prediction of the pion form factor in the pQCD approach is not precise.

Inelastic final-state interactions in B → VV →π K processes

Abstract. We study the final-state interactions in B →π K decays through B → VV →π K processes where the inelastic rescattering occurs via single pion exchange. The next-to-leading order low-energy effective Hamiltonian and Bauer-Stech-Wirbel (BSW) model are used to evaluate the weak transition matrix elements and final-state interactions. We found that the final-state interaction effects in B →ρ K*→π K processes are significant. The Fleischer-Mannel relation for the Cabibbo-Kobayashi-Maskawa (CKM) angle γ can be significantly
modified.

The reliability of pQCD approach in pion electromagnetic form factor
The pion electromagnetic form factor with leading and next-to-leading twist corrections are studied in the framework of pQCD approach. We find that, at small momentum transfer regions, Sudakov effects cannot provide a strong enough suppression of the non-perturbative contributions coming from large transverse separations, but at large momentum transfer region, non-perturbative contributions can be effectively suppressed. So pQCD approach can be applied at large momentum transfer region. At the energy region where experiment can access so far, i.e. Q < 4GeV, pQCD prediction can not be precise because there may be a quite large part of contributions coming from non-perturbative region. The calculation of power corrections may not be performed systematically in pQCD framework.

The Structure Function of Six-Quark Cluster and the EMC Effect
Based upon the experiments on electric form factor for deutron use is made of the valon model to determine the valon distribution functions in a six-quark cluster. By using the QCD evolution equation, the dependence of the structure function of a six-quark cluster is obtained. The EMC effect is discussed and it is pointed out that the distortion of the nucleon structure function in nuclei may be ascribed to the contributions from the six-quark cluster(for ) and the meson cloud(for ).

Rescaling for Kaon Structure Function
We use the valon model to analyse the dynamical rescaling of x in the inelastic structure functions and point out that the rescaling is just the delta approximation of the valon distribution functions. We apply the contribution of valence quarks to the mass of a hadron bound state to determine a few parameters for the x-rescaling and thus obtain the Kaon structure functions. The result is in good agreement with experimental data.

Collective Transverse Flow in Intermediate Energy Heavy-Ion Collisions
Within the hadronic transport model IBUU04, we study the density-dependent symmetry energy by using the neutron-proton differential flow from the 132Sn+124 Sn reactions at beam energies of 200, 400, 600 and 800 MeV per nucleon. The strong effect of the symmetry energy is shown at the incident beam energy of 400 MeV/A. The small medium-effect of the neutron-proton differential flow is also found. We also study the neutron-proton differential flows with impact parameters of 3, 5, 7 fm. It is found that in semi-central collisions the sensitivity of the neutron-proton differential flow to the symmetry energy is larger.

Colour Dipole Picture for Deep Inelastic Scattering in the Collinear Factorization Scheme
The colour dipole picture for deep inelastic scattering processes is generalized in the collinear factorization scheme. We show that a duality between the colour dipole picture and scattering picture is lost in higher twist amplitudes.
