Looking for DPS patterns using $J / \psi$ and high $p_{T}$ tracklets

We present a standalone analysis of p-p collisions at $ \sqrt{s} = 5.02 $ TeV for $ J/\psi $ decaying into dimuons and also a feasibility study of $ p_{T} $ correlations with different observables of tracklets in the central barrel. In the latter analysis, it was found that both $ \delta \phi $ and $ \chi^{2} $ (dist) could be used efficiently to select high $ p_{T} $ tracklets. These analyses are then implemented in studying the Double Parton Scattering with $ J/\psi $ and two jets to estimate the effective cross section parameter.
