Within the hidden local symmetry framework, the Dalitz decay η→Ve+e-is studied with the vector meson dominance model. It is found that the partial width Γ(η→ωe+e-)≈40 e V and branching ratio B(η→ωe+e-...

The Bc → Bsπ decay is studied with the perturbative QCD approach. Three types of wave functions for Bs meson are considered. The transition form factor F0Bc → Bsπ (0) and the branching ratio IBr(Bc → Bsπ) ar...

Newton’s law of gravity is a theory of instantaneous action at a distance.However,Einstein’s general relativity states that the speed of gravity equals the speed of light,which is finite.Therefore,it is a worthy pro...

The currently accepted value for the upper limit on the photon rest mass comes from a rough estimate based on the solar wind method.We reconsider this method and present a more detailed analysis of the electromagnetic...
