Glueballs and fractional anomalous determinants at nonzero $\theta$, and the decays of the X(2370)

Francesco Giacosa, Shahriyar Jafarzade, Győző Kovács +3

Using fractional anomalous determinants, we construct a model of the trace and axial anomalies of a $SU(3)$ gauge theory at nonzero $\theta$ angle through the couplings to scalar and ps…
