Measurements at the LHC have already reached a remarkable precision. This opens up new opportunities for New Physics searches. However, the accuracy of experimental data must be matched by the theoretical one. In this talk, I will discuss recent progress in precision QCD predictions.

Densities in neutron star cores can reach up to ten times the density of a normal atomic nucleus, and
the stabilising effect of gravitational confinement permits long-timescale weak interactions. This
generates matter that is neutron-rich, and opens up the possibility of stable states of strange matter,
something that can only exist in neutron stars. Our uncertainty about the nature of...

The EMC effect, the phenomenon by which quark distributions are modified in bound nucleons, has defied explanation since its discovery over 30 years ago. Recently, there have been indications, experimentally and theoretically, that the EMC effect may be linked to high-momentum nucleons. Rather than the EMC effect being caused by a modest modification in all nucleons, it is possible that highly...

J/$\psi$ measurements in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV clearly show a smaller suppression than the one expected from color screening, when compared to binary-scaled pp collisions.
