Quark polarization and spin correlations have been extensively researched for top quarks at the LHC but have not yet been explored to the same degree for b, c, and s quarks. We want to look into di-jet production pp -> q q_bar where q can be b, c or s. We propose algorithms that will give background and signal event discrimination based on triggers in CMS and ATLAS. We run these algorithms in simulations of the above processes to get the expected precision of measurements that can be achieved using these algorithms. Our results show some channels with good statistical uncertainty, even with the data from run-2 of the LHC. We have also looked at the effect of dimension-six BSM operators on the polarization and spin correlations.
