      Introduction to physics of EIC (1/4) 1h

      In four lectures basic theoretical ideas underlying future studies at the EIC
      will be presented, including a historic perspective of the subject.
      The tentative titles of the lectures are the following:
      1. From Greeks to QCD
      2. Partonic structure of nucleons
      3. Parton saturation
      4. Personal overview of EIC studies
      The underlying theme is the QCD at action.

      Factorisation for parton distributions and related quantities (1/2) 1h

      Abstract: I review some of the main concepts that allow us to separate process-dependent dynamics from properties of the proton in high-energy collisions. Topics covered are collinear factorisation, scale evolution, operator product expansion, factorisation for TMDs.

      Diffraction in hadronic collisions (1/2) 1h

      Diffractive events in hadronic collisions are classes of events characterized by the large interval of rapidity which is devoid of any hadronic activity. Such gaps are called large rapidity gaps, since they often span several units of rapidity. At HERA electron-proton collider, about 10% of events were classified as diffractive. In such events the proton either is scattered elastically or is dissociated into a state with the same quantum numbers, separated from the rest of hadronic activity . Diffraction is very interesting and important phenomenon, since its understanding may shed light into the confinement, low x parton evolution, including non-linear phenomena, and nuclear shadowing. In these lectures I will present basic introduction to diffraction phenomena, mainly in DIS, both from theoretical and phenomenological perspective and give the prospects for the measurements at the Electron Ion Collider.

      The physics of the QCD energy-momentum tensor (1/2) 1h

      In QCD, the energy-momentum tensor has been recognized as a central object allowing one to address the questions of hadron mass, spin and pressure forces. These are key motivations for the physics case of the EIC project in the US. In these two lectures, we will discuss various interesting and non-trivial aspects of the QCD energy-momentum tensor that have recently attracted a lot of attention, like e.g. the questions of its definition, renormalization, decomposition into quark and gluon contributions, interpretation as spatial distributions, sum rules derived from Poincaré symmetry, and links with experimental
      observables.
