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…
Is Yang-Mills Theory Unitary in Fractional Spacetime Dimensions?
Qingjun Jin, Ke Ren, Gang Yang +1
We present concrete evidence that Yang-Mills theory exhibits non-unitarity in non-integer spacetime dimensions. This violation of unitarity stems from evanescent operators that, wh…
Gluonic evanescent operators: two-loop anomalous dimensions
Qingjun Jin, Ke Ren, Gang Yang +1
Evanescent operators are a special class of operators that vanish in four-dimensional spacetime but are non-zero in dimensions. In this paper, we continue our systematic s…
Gluonic evanescent operators: classification and one-loop renormalization
Qingjun Jin, Ke Ren, Gang Yang +1
Evanescent operators are a special class of operators that vanish classically in four-dimensional spacetime, while in general dimensions they are non-zero and are expected to have…
