  This paper aims at reproducing quantum mechanical (QM) spin and spin
entanglement results using a realist, stochastic, and local approach, without
the standard QM mathematical formulation. The concrete model proposed includes
the description of Stern-Gerlach apparatuses and of Bell test experiments.
Single particle trajectories are explicitly evaluated as a function of a few
stochastic variables that they assumedly carry on. QM predictions re retrieved
as probability distributions of similarly-prepared ensembles of particles.
Notably, it is shown that the proposed model, despite being both local and
realist, is able to violate the Bell--CHSH inequalities by exploiting the
coincidence loophole and thus intrinsically renouncing to one of the Bell's
assumptions.
