While HERA taught us that the proton is mainly occupied by gluons for Bjorken x < 10−2, the LHC
gives the possibility to measure the gluonic structure of the proton and nuclei at Bjorken x ∼ 10−5.
Measurements of photon-induced reactions in ultra-peripheral collisions (UPCs) of Pb-Pb and p-Pb nuclei at the LHC have been performed with ALICE in the past years. In these...
In quasi-elastic proton-proton collisions at the LHC, central exclusive production (CEP) of vector mesons can take place via the fusion of a photon and a pomeron (a colourless strongly-coupled object with the quantum numbers of the vacuum), while the protons remain intact. The central exclusive production of $J/\psi$ and $\psi$(2S) mesons provides clean events, which is uncommon at hadron...
A unique feature of generalised parton distributions is their relation to the QCD energy-momentum tensor. In particular, they provide access to the distributions of pressure and shear stress induced by its quark and gluon structure. In principle the pressure distribution can be experimentally determined in a model-independent way from a dispersive analysis of deeply virtual Compton scattering...
Diffractive events can be divided in two categories. First, in so called coherent diffraction the target remains on its ground state. In incoherent diffraction, on the other hand, the target breaks up, but the event is still diffractive, i.e. there is no net color charge transfer to the target. One advantage of diffractive processes is that the total momentum transfer can be measured by...
Nuclear dynamics at short distances among nucleons is one of the most outstanding phenomena in nuclear physics. Understanding the role of QCD in generating nuclear forces is important for uncovering the underlying physics of Short-Range Correlations (SRCs). In recent years, SRCs has been observed from light to heavy nuclei using fixed target experiments at Jefferson lab via high energy...
Generalized transverse momentum-dependent parton distribution functions (GTMD-PDFs) are the building blocks that encode the spatial and momentum distribution of quarks and gluons inside hadronic matter. In the forward region (small-x) of deeply inelastic scattering (DIS) experiments, various inclusive and exclusive multi-particle observables depend only on two types of GTMD-PDFs: the dipole...
