Conference Presentations

The HERMES experiment collected from 1995 to 2007 a wealth of deep-inelastic scattering data using 27.6 GeV longitudinally polarised electrons and positrons and various unpolarised as well as longitudinally and transversely polarised gas targets. This allowed for a series of diverse measurements. [...]

After fifty years of investigations, the nucleon structure is still far from being understood and continues to represent a unique test bench for QCD. Despite the enormous progresses achieved in five decades of deep-inelastic scattering (DIS) experiments, a number of crucial open questions are still on the carpet and subject of intense theoretical and experimental studies. [...]

The HERMES experiment has collected a wealth of deep-inelastic sca ering data using the 27.6 GeV polarized electron or positron beams at HERA and various pure gas targets, both unpolarized and polarized. is allowed for a series of unique measurements. [...]

We present a parton shower based on Transverse Momentum Dependent (TMD)parton distributions obtained with the Parton Branching method. We investigatehow well the TMD parton shower reproduces the TMD parton distributions.Applications of the TMD parton shower to LHC processes will be presented..

I would like to report on a calculation of inclusive Z boson production in proton-lead col-lisions at the LHC taking into account the transverse momenta of the initialpartons. We use the framework of kT-factorization combining transverse momentum dependent parton distributions (TMDs) with off-shell matrix elements.In order to do it we need to construct appropriate TMDs for lead nuclei which is done using the parton branching method. [...]

We present a new determination of Transverse Momentum Dependent (TMD)parton distributions applying the Parton Branching method. The PB TMDs areobtained from fits to precision DIS data using DGLAP splitting functions atleading and higher order. [...]

We use the kT–factorization approach to calculate total and differential cross sections of associated production of prompt photons and hadronic jets at the LHC energies. Our consideration relies on the pegasus Monte-Carlo generator with implemented ℴ(αα2s) off-shell gluon–gluon fusion subprocess g*g* → γqq− and several subleading quark-initiated contributions from ℴ(ααs) and ℴ(αα2s) subprocesses, taken into account in the collinear limit. [...]

Like many other quantities, Generalized Parton Distributions canbe represented in terms of Light-Cone Wave Functions. This connection hasseveral important physics aspects, which I review with a historicalperspective, from early work at the turn of the millenium to recentdevelopments..
