Determination of hybrid charmonium meson masses

Gaurav Ray, Craig McNeile

摘要:

本文报道了最轻的粲混合介子多重态的质量和衰变常数的初步研究结果。我们得到精确的测量的$1^{-+}$状态通过使用变分基础和大量的配置在三个晶格间距。我们使用交错的费米子运营商使用的配置与HISQ行动与2+1+1动力学风味。混合的矢量混合与$J/ψ$的检查和初步约束矢量混合衰变常数。

英文摘要:

We report initial results from our study of the masses and decay constants of the lightest multiplet of charmonium-like hybrid mesons. We obtain precise measurements of the $1^{-+}$ state through the use of a variational basis and a large number of configurations at three lattice spacings. We use staggered fermion operators using configurations generated with the HISQ action with 2+1+1 dynamical flavours. The mixing of the vector hybrid with the $J/ψ$ is examined and a preliminary bound on the vector hybrid decay constant is presented.
