We review a broad range of phenomena in diffraction in the context of hadron–hadron,
hadron–nucleus collisions and deep inelastic lepton–proton/nucleus scattering focusing on …

We outline a strategy of how to search for QCD instantons of invariant mass 20–60 GeV in
diffractive events in low-luminosity runs at the LHC. We show that, by imposing appropriate …

We study the possibility to observe heavy (M inst> 60 GeV) QCD instantons at the LHC in
events with one or two tagged leading protons including fast simulation of detector and pile …

The transverse momentum spectra and their multiplicity dependence serve as key tools for
extracting parameters to be compared with theoretical models. Over the past decade, the …

The transverse momentum spectra and their multiplicity dependence serve as key tools for
extracting parameters that can be compared with theoretical models. This comparison aims …

Events where the two leading jets are separated by a pseudorapidity interval devoid of
particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at s= 13 …

We study the high-energy limit of QCD using the DGLAP, BFKL and B-JIMWLK frameworks
based on non-standard perturbative re-summation techniques to calculate the theory …

We describe recent results from CMS and TOTEM on hard diffraction, diffractive jets and jet
gap jet events. We also give the first sensitivities and limits on quartic anomalous couplings …

The dissertation presents measurements of diffractive dijet production in proton-proton
collisions at the centre-of-mass energy $\sqrt {s} $= 13 TeV. The measurements are based …

The new framework for the simulations of hard diffractive events in photoproduction within
Pythia 8 is presented. The model, originally introduced for proton-proton collisions, applies …
