标题： The gluonic excitation of the three-quark system in SU(3) lattice QCD

摘要： 我们首次在SU(3)格点QCD中研究了三个夸克(3Q)系统中的胶子激发，其中$\beta$=5.8，$16^3 \times 32 $在冻结水平上。 对于空间固定的3Q系统，我们测量了胶子激发态势能，这对应于通量管图中的通量管振动能量。 在介子尺度下，3Q系统中的最低胶子激发能量约为1GeV。 这种大的胶子激发能量预计会带来不包含胶子模式的简单夸克模型的成功。 显示英文摘要

摘要： We present the first study of the gluonic excitation in the three-quark (3Q) system in SU(3) lattice QCD with $\beta$=5.8 and $16^3 \times 32 $ at the quenched level. For the spatially-fixed 3Q system, we measure the gluonic excited-state potential, which corresponds to the flux-tube vibrational energy in the flux-tube picture. The lowest gluonic-excitation energy in the 3Q system is found to be about 1GeV in the hadronic scale. This large gluonic-excitation energy is expected to bring about the success of the simple quark model without gluonic modes.
