    A method to extract resonance pole information from single-channel partial-wave amplitudes based on a Laurent (Mittag-Leffler) expansion and conformal mapping techniques has recently been developed. This method has been applied to a number of reactions and provides a mo...

    Abstract We analyze a possible scheme of the evolution of the universe by studying the bound state energy spectrum in conformal gravity and investigating transitions involving spontaneous changes of the cosmological constant via excitation followed by deexcitation invol...

    Abstract A set of unitary relativistic equations for the coupled πNN-NN system is used to describe the processes π d → π d, π d ↔ NN and NN → NN at intermediate energies where the alleged dibaryon resonance effects may manifest themselves.

    We investigate an extension of the Minimal Standard Model by right-handed neutrinos (the $\nu$MSM) to incorporate neutrino masses consistent with oscillation experiments. Within this theory, the only candidates for dark matter particles are sterile right-handed neutrino...

    Chiral symmetry breaking in a purely fermionic theory is investigated by the help of the renormalization group method. The RG equation for the running mass $m_k$ admits a solution with vanishing bare mass and finite physical mass. The running Fermi coupling constant, $G...

    Abstract The SU(3) gluon condensate is determined from a fit to the Creutz ratios of Wilson loop expectation values taken from new Monte Carlo data. The result agrees very well with the phenomenological value.

    Abstract The properties of interactions of anomalous nuclei are discussed in terms of two broad classes of models, “hard” and “soft”. Hard models appear to be favoured by the data, and some estimates of experimentally measurable cross sections are given. A small value (...

    We address the issue of whether extra dimensions could have an infinite volume and yet reproduce the effects of observable four-dimensional gravity on a brane. There is no normalizable zero-mode graviton in this case, nevertheless correct Newton's law can be obtained by...
