论文摘要
我们介绍了用$ j^{pc} = 1^{ - } $，$ 2^{ - } $和$ 3^{ - } $中的激发光中共振的晶格QCD中的第一个计算。使用确切的SU（3）风味对称性，用于伪尺度矢量散射的单点表示，我们发现两个$ 1^{ - } $共振，更较轻的宽状态和更重的狭窄状态，一个宽阔的$ 2^{ - } $ resonance $ p $ - p $ - p $ - - $ p $ - w $ - $ -waves和$ 3^$ 3^^$} - 我们将连接与实验$ω^\ star_j，ϕ^\ star_j $共振衰减到$πρ$，$ k \ bar {k}^*$，$ηΩ$和其他最终状态。
We present the first calculation within lattice QCD of excited light meson resonances with $J^{PC} = 1^{--}$, $2^{--}$ and $3^{--}$. Working with an exact SU(3) flavor symmetry, for the singlet representation of pseudoscalar-vector scattering, we find two $1^{--}$ resonances, a lighter broad state and a heavier narrow state, a broad $2^{--}$ resonance decaying in both $P$- and $F$-waves, and a narrow $3^{--}$ state. We present connections to experimental $ω^\star_J, ϕ^\star_J$ resonances decaying into $πρ$, $K\bar{K}^*$, $ηω$ and other final states.
