چکیده

In this article, we take the point of view that the strange-bottomed (0, 1) mesons Bs0 and Bs1 are the conventional bs̄ mesons, and calculate the electromagnetic coupling constants d, g1, g2 and g3 with the light-cone QCD sum rules. Then we study the radiative decays Bs0 → B sγ, Bs1 → Bsγ, Bs1 → B sγ and Bs1 → Bs0γ, and observe the decay widths are rather narrow. We can search the strange-bottomed (0, 1) mesons in the invariant Bsπ 0 and B sπ 0 mass distributions in the strong decays or in the invariant B sγ and Bsγ mass distributions in the radiative decays.

The strong decays of the π quark-antiquark states are investigated in the framework of the 3 P 0 meson decay model. It is found that the π(2070), η(2100), and η(2225) appear to be the convincing 4 1 S 0 q ¯ q states while the assignment of the η(2010) and η(2190) as the 4 1 S 0 isoscalar states is not favored by their widths. In the presence of the π(2070), η(2100), and η(2225) being the member...

With the assumption that the X(1835) and η(1760) recently observed by the BES Collaboration are the 3 1 S 0 meson states, the strong decays of these two states are investigated in the 3 P 0 decay model. We find that the predicted total widths of the X(1835) and η(1760) can be reasonably reproduced with the X(18350) − η(1760) mixing angle lying on the range q ¯ q members seems reasonable.

We discuss a possibility of detecting a coherent photon pair emission and related radiative neutrino pair emission from excited atoms. It is shown that atoms of lambdaand ladder-type three level system placed in a pencil-like cylinder give a back to back emission of two photons of equal energy ∆/2, sharply peaked with a width ∝ 1/( target size) and well collimated along the cylinder axis. This ...
