Non-Hermitian Structure and Exceptional Points in Yang-Mills Theory from Analytic Continuation of Nc
Qingjun Jin, Ke Ren, Gang Yang +1
We show that analytic continuation of the number of colors, Nc, naturally endows Yang-Mills theory with a non-Hermitian structure. By examining the spectrum of the dilatation opera…

Gluonic evanescent operators: negative-norm states and complex anomalous dimensions
Qingjun Jin, Ke Ren, Gang Yang +1
In this paper, we build on our previous work to further investigate the role of evanescent operators in gauge theories, with a particular focus on their contribution to violations…
