Productions of σmeson in J/ψand ψ(2s) decays
Bing An Li
Productions of scalar meson in the decays of J/ψ-->ω+σ, J/ψ-->γ+σand ψ(2s)-->ω+σ, γ+σand ee^+ annihilations in the regions of J/ψand ψ(2s) are studied.
ee^+-->π^0γand form factor of π^0γ^*γ^*
Bing An Li
The form factor π^0γ^*γ^* is obtained to the next leading order of derivative expansion of the chiral anomaly and the VMD. As a test the form factor has been used to calculate the…
Correction of the low energy theorem of γ\to2πanomaly
Bing An Li
A correction of the low energy theorem of the γ\to3πanomaly has been found. A_{3π}(0,0,0) and the cross section are calculated. Theory agrees with data. There is no new adjustable…
Form factor of π^0γ^*γ^* and contribution to muon g-2
Bing An Li
The transition form factor of $π^0γ^*γ^* is found. The slope is predicted. The contribution to muon g-2 is calculated.
Invalid Ward-Takahashi identities and broken unitarity of the SM
Bing An Li
It is found that in the SM the Ward-Takahashi(WT) identities of the axial-vector currents and the charged vector currents of fermions are invalid after spontaneous symmetry breakin…
Broken unitarity of the SM and a new theory of EW interactions
Bing An Li
It shows that because of the axial-vector coupling and the coupling with fermions of different masses the untarity of the SM is broken at the scale of 10^{14}GeV. A new theory of E…
