The physical meaning of scattering matrix singularities in coupled-channel formalisms
S. Capstick, A. Svarc, L. Tiator +8
The physical meaning of bare and dressed scattering matrix singularities has been investigated. Special attention has been attributed to the role of well known invariance of scatte…

On the definition of the Δmass and width
D. Djukanovic, J. Gegelia, S. Scherer
In the framework of effective field theory we show that, at two-loop order, the mass and width of the Δresonance defined via the (relativistic) Breit-Wigner parametrization both de…

Asymptotic freedom in massive Yang-Mills theory
J. Gegelia
An effective field theory model of the massive Yang-Mills theory is considered. Assuming that the renormalized coupling constants of 'non-renormalizable' interactions are suppresse…
