We determine the value of the omega -rho- pi mesons coupling (g_{omega rho pi}), in the context of the vector meson dominance model, from radiative decays, the omega -> 3 pi decay width and the e^+e^-...
Nucleon, Delta and Omega excited state spectra at three pion mass values
Nucleon Delta Omega excited state spectra three pion mass values
2011/1/13
The energies of the excited states of the Nucleon, D and W are computed in lattice QCD, using
two light quarks and one strange quark on anisotropic lattices. The calculations are performed at three v...
根据现有的关于(ΩΩ)0+的生成截面的理论计算, 利用HIJING事例产生器研究
了s nn=200GeV下Au-Au中心碰撞中(ΩΩ)0+和NΩ022产生过程, 分别对(ΩΩ)0+的电磁作用产生过程和两步产生过程中的第一步过程进行了(ΩΩ)0+产率的计算, 给出了(ΩΩ)0+产额的上限. 对于电磁作用过程, 其产率为(1.097±0.293)×10-10. 同时我们也对(NΩ)022进行了初步...
