Track: QCD and Hadron Structure
Double parton scattering, interactions where two pairs of patrons interact in two separate hard interactions, give us a way to study and test the correlations between two partons inside a hadron. The theoretical framework to systematically calculate these interactions have seen a remarkable development in the last decade.

I discuss photon-proton proton initiated double parton scattering (DPS) due to the limited information on the proton structure obtained from p-p collision data. In DPS initiated by quasireal photons, spitting in a qq̄ pair, the interaction rate is controlled by the virtuality. $\sigma_{DPS}$ has been calculated for the four jet production at HERA and a significant contribution is found. Moreover, ... More

The light kaonic atoms high precision X-ray spectroscopy is a key tool for understanding the low-energy QCD in the strangeness sector. The SIDDHARTA-2 collaboration is ready to perform the challenging measurement of the kaonic deuterium transitions to the fundamental level at the DAΦNE collider of the INFN-LNF. The contribution presents the experimental apparatus and the first results obtained du ... More

We discuss the production mechanism of a fully charm tetraquark, discovered by LHCb. including SPS and DPS mechanisms. We construct a coalescence model of the tetraquark production. We calculate the distribution in $p_{t,4c}$ in the resonance mass window. The cross section for the $J/\psi J/\psi$ is also calculated. We do similar analysis for FCC. We discuss also production of \$c \bar c b ... More
