%0 Journal Article %T The relationship between four-dimensional θ=π Yang-Mills theory and the two-dimensional Wess-Zumino-Novikov-Witten model %A 寇谡鹏 %J 中国物理 B %D 2002 %I %X Used the dimensional reduction in the sense of Parisi and Sourlas, the gauge fixing term of the four-dimensional Yang-Mills field without the theta term is reduced to a two-dimensional principal chiral model. By adding the θ term (θ=π), the two-dimensional principal chiral model changes into the two-dimensional level 1 Wess-Zumino-Novikov-Witten model. The non-trivial fixed point indicates that Yang-Mills theory at θ=π is a critical theory without mass gap and confinement. %K Yang-Mills %K field %K dimensional %K reduction %K Wess-Zumino-Novikov-Witten %K model %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=CD8D6A6897B9334F09D8D1648C376FB4&aid=E7746FD247AFA2273F14991E06FEB9B3&yid=C3ACC247184A22C1&vid=708DD6B15D2464E8&iid=5D311CA918CA9A03&sid=A1BB529A18D3A83E&eid=7B927C26AC9ED104&journal_id=1009-1963&journal_name=中国物理&referenced_num=0&reference_num=0
