Nuclear Parton Distribution Functions (nPDFs) are the non-perturbative objects that describe the behavior of partons in a nuclear medium, a natural extension of the free proton PDFs. Despite more than three decades of thorough study, the picture of nPDFs is far from being complete. In this talk I will present the current status of our knowledge and briefly discuss how current and future...

The proton gluon distribution function increases rapidly with decreasing momentum fraction $x$ at fixed $Q^2$, but cannot increase indefinitely as $x$ decreases. Gluon saturation is expected at a low $x$ value when gluon recombination balances gluon splitting. The nuclear (with atomic mass number A) gluon distribution is approximately $A^{1/3}$ larger than the nucleon gluon distribution...

For almost twenty years, the STAR experiment at RHIC has played a leading role in expanding the frontier of nucleus-nucleus collisions and the interaction of spin-polarized beams of protons. In coming years, the STAR forward upgrade will enable new insight into cold nuclear matter, probing this physics at high and low regions of $x$. The proposed detector upgrades consist of electromagnetic...

Over past years DIS $e$+$p$ data have provided crucial inputs to the phenomenology of $p$+$p$/A & A+A collisions. Largest uncertainties in such modeling arise from the spatial and momentum distribution of partons inside nuclei at small-$x$. In this talk, I will discuss such issues and highlight a few recent measurements of the charge inclusive and charge dependent angular correlations from...

Collimated jets of hadrons and their substructure play a central role at present day and future collider experiments. In particular in the past years, it has been realized that the measurement of hadron distributions inside jets can provide valuable information about QCD. On the one hand, identified hadrons can be used to precisely map out the energy distribution inside jets both in the...
