Disconnected quark loop contributions to nucleon observables using $N_f=2$ twisted clover fermions at the physical value of the light quark mass

We compute the disconnected quark loops contributions entering the determination of nucleon observables, by using a $N_f=2$ ensemble of twisted mass fermions with a clover term a…
