高激发态介子的光谱是纯库仑的吗？
Is the spectrum of highly excited mesons purely coulombian?
摘要：
我们表明，一个静态的中心势可以提供一个精确的描述高激发光无味介子。由于弦的断裂，这个势在足够大的夸克-反夸克距离处变成色电型，从而产生库仑谱。同样的结论可以通过我们分析的直接延伸而推断出任何其他介子扇区。
英文摘要：
We show that a static central potential may provide a precise description of highly excited light unflavoured mesons. Due to string breaking this potential becomes of chromoelectric type at sufficiently large quark-antiquark distances giving rise to a coulombian spectrum. The same conclusion can be inferred for any other meson sector through a straightforward extension of our analysis.
