Abstract:
The experimental phenomenon-the helicity inversion of laser (photons) during reflection has been explained based on the quantum theory of the laser (photons) propagation through an optical helix. It is found that the instant process of the laser(phot...

We report a measurement of the absolutely inclusive semileptonic branching fractions of D－ and D0 mesons, using a data sample of 22.3pb－1 collected with BES detector at BEPC e+e－ Collider at s=4.03GeV and based on the method of "combinative D+ and D0...

In this paper an important character was found that the final hadron multiplicities of direct J/ψ decays satisfy the same universal mass dependence as that in e+e－→q0q0 continuum events. This indicates that the fragmentation of quark and gluon to had...

Abstract:
In previous calculations of the strong decay of a charmonium,the first-order momentum dependence of the quark propagator is kept. It was found that the finite-size vertex correction to the Γ(J/ψ→3g) process is large. In this paper we calculate the tw...
