Lattice QCD calculation of the pion-nucleon coupling ${\bar{g}}_0$ induced by the QCD $\Theta$-term

Fangcheng He, Tanmoy Bhattacharya, Rajan Gupta +1

We present lattice QCD results for the CP violating pion-nucleon coupling ${\bar{g}}_0$ induced by the QCD $\overline{\Theta }$ term from the analysis of three 2+1+1-flavor ensembles generat…
