中心对称性与哈格多恩谱

Center symmetry and Hagedorn spectrum

Adi Armoni, Thomas D. Cohen, Srimoyee Sen

摘要:

本文探讨了大Nc规范理论具有Hagedorn谱的猜想,当且仅当它们是限制的,并且是显式中心对称或涌现中心对称.支持这一猜想的证据。许多类大Nc规范理论被认为是。在所有的情况下,我们发现,理论,存在一个强大的可扩展性参数的哈格多恩频谱在大NC也被认为是限制,并拥有一个明确的中心对称或有一个强大的可扩展性参数的存在下出现的中心对称在大NC。相反,我们所考虑的所有理论,如果被认为在大Nc处不具有哈格多恩谱,要么被认为是没有约束的,要么被认为缺乏涌现中心对称性。这与基于猜想的预期是一致的。

英文摘要:

This paper explores the conjecture that large Nc gauge theories have a Hagedorn spectrum, if, and only if, they are confining and posses an explicit or emergent center symmetry. Evidence in support of this conjecture is presented. Many classes of large Nc gauge theories are considered. In all cases, we find that theories for which there exists a strong plausibility argument for a Hagedorn spectrum at large Nc are also believed to be confining and possess either an explicit center symmetric or have a strong plausibility argument for the existence of an emergent center symmetry at large Nc . Conversely, all theories we considered which are believed not to have a Hagedorn spectrum at large Nc, either were known not to be confining or else were believed to lack an emergent center symmetry. This is consistent with expectations based on the conjecture.
