摘要
本文准确求解了一个有费米子加倍的格点 U(1)规范模型。结果显示正反费米子组成的介子态出现相应的加倍问题。进一步,我们证明 Susskind 费米子方案可以消除介子态的加倍。
A(1+1)-dimensional lattice U(1)gauge model with fermion species doubling is solved ex- actly.The results show that doubling exists for meson states composed of fermions and antifer- mions.Furthermore we prove that Susskind fermions can beat the doubling of meson states.
