Members of this group focus their research interests on potential applications of particle physics in medicine, in particular in the treatment of cancer. Hadron radiotherapy, i.e., treatment of cancer with the help of irradiating tumours with proton and light ion beams, is a modern treatment modality which allows to spare surrounding healthy tissues and limit the radiation-induced burden to the whole organism.

In the field of mathematical physics, new equations for massless fields which are invariant under the Galilei transformation have been derived in papers [1-4] by contraction of relativistic wave equations. The resulting equations can be used for description of many physically consistent systems, e.g. electromagnetic fields in many different media or within the framework of Galilean Chern-Simons models. Classification of all linear and non linear Galilean invariant equations for massless fields has been accomplished as well. The full text >>
String theory is the only known theory that consistently unifies all four fundamental interactions: the electromagnetic, gravitational and strong and weak nuclear forces. Its consistency with quantum mechanics makes it also the leading candidate for quantum gravity theory. String theory faces two major

An important problem of perturbative QCD is an accurate determination of the strong coupling αs from hadronic τ decays. The decay width Rτ can be determined from the two-point correlation functions Π(s) which are the Fourier transforms of vacuum expectation values of current products.

We play an active role in preparation and development of forward proton detectors for ATLAS experiment. Within a broader international collaboration we proposed to ATLAS to instrument regions 220m and 420m away from the interaction point with forward proton detectors. Installation of the detectors would increase

For more than 10 years we are participating in the DZero experiment which detects and analyzes the results of the proton-antiproton interactions provided by Tevatron collider in Fermilab. We are focusing on jets - collimated sprays of particles which are fingerprints of violently scattered proton constituents, quarks

The theoretical study and the experimental exploration of the internal structure of protons and neutrons (nucleons) have recently entered a new phase. Over the past 40 years an understanding of nucleons in terms of elementary constituents (partons, i.e. quarks and gluons) has gradually and successfully emerged. Much has been learned about the nucleon in terms of its “one-dimensional” parton structure, relevant when partons are assumed to move co-linearly with their parent nucleon, and encoded in the so-called parton distribution functions (PDFs).

Study of heavy ion collisions at ultra high energies represents a hot issue in the contemporary nuclear and particle physics. A fundamental motivation for this study is to verify the prediction of the current theory of the strong interaction (called Quantum Chromo-Dynamics), which implies that at very high temperatures and very high densities of the nuclear matter, quarks and gluons should no longer be confined inside composite particles. Instead they should exist freely in a new state of matter known as quark-gluon plasma (QGP). The full text >>
The main aim of the experiment ATLAS in the LHC at CERN is to test the contemporary Standard Model of particle physics up to the highest center-of-mass energies of 14 TeV. Especially the last missing Standard Model fundamental particle – Higgs boson is searched. Or supersymmetrical particles and other exotic processes.
