纯N=1超杨米尔斯中的Hagedorn温度和开QCD弦快子

The Hagedorn Temperature and Open QCD-String Tachyons in Pure N=1 Super Yang-Mills

Adi Armoni, Timothy J. Hollowood

摘要:

我们考虑具有Hagedorn态密度的大N约束规范理论。在这样的理论中,一对色单态源之间的势可以在临界距离r_c = 1/ T_H处发散。我们特别考虑了纯N=1的超杨-米尔斯理论,并认为当畴壁和反畴壁被带到r_c附近时,相互作用势可以用"开放的QCD弦通道“来描述.我们解释的分歧的潜在的快子模式,并将其质量的Hagedorn温度。最后,我们将我们的结果与Kutasov和Seiberg的定理,并认为存在一个开放的弦快子模式的环振幅意味着指数密度的状态在UV的封闭弦通道。

英文摘要:

We consider large-N confining gauge theories with a Hagedorn density of states. In such theories the potential between a pair of colour-singlet sources may diverge at a critical distance r_c = 1/ T_H. We consider, in particular, pure N=1 super Yang-Mills theory and argue that when a domain-wall and an anti domain-wall are brought to a distance near r_c the interaction potential is better described by an ``open QCD-string channel''. We interpret the divergence of the potential in terms of a tachyonic mode and relate its mass to the Hagedorn temperature. Finally we relate our result to a theorem of Kutasov and Seiberg and argue that the presence of an open string tachyonic mode in the annulus amplitude implies an exponential density of states in the UV of the closed string channel.
