Abstract
We calculate the relativistic correlation function for a hybrid system of a photon and a Dirac particle. Such a system can be produced in decay of another spin-$\frac{1}{2}$ fermion. We show that the relativistic correlation function, which depends on particle momenta, may have local extrema for fermion velocity of the order $0.5c$. This influences the degree of violation of the Clauser-Horne-Shimony-Holt inequality.
