Abstract:
The hadronic decay process J/ψ→V1+X,X→V2+V3,V2、V3→2P or 3P(Vi and P stand for vector and pseudoscalar meson,respectively)has been discussed by using the generalized moment analysis method in this paper.The formulas of moment corresponding to the inte...

Abstract:
In this paper the experimental value of radiative correction Δr was derived from the new data of sin 2θw and W boson mass Mw given by LEP,CDF and other collaborations.A careful comparison of (Δr)exp with the standard model expectation was carried out...

Abstract:
In this article,we discussed the Hamiltonian formalism of BFOFW model,studied its Dirac canonical quantization and BFV-BRST quantization.We proposed a new kind of gauged WZNW theories,which was called in the text generalized BFOFW model.

Abstract:
The free energy on genus g Riemann surface is derived by introducing two-dimensional scalar field and using Vafa's operator approach.The modular duality relation of specific heat is also obtained.
