本文用欧氏格点算符的谱函数分析方法研究了夸克胶子等离子体中P波底鎓态的命运。在高度各向异性的晶格上，用两种轻夸克味的晶格QCD模拟得到了双夸克子，对底夸克进行了非相对论处理。我们发现明确的迹象融化后立即解除禁闭过渡。
We study the fate of P wave bottomonium states in the quark-gluon plasma, using a spectral function analysis of euclidean lattice correlators. The correlators are obtained from lattice QCD simulations with two light quark flavours on highly anisotropic lattices, treating the bottom quark nonrelativistically. We find clear indications of melting immediately after the deconfinement transition.
