Finding the sigma pole by analytic extrapolation of scattering data
Irinel Caprini
We investigate the determination of the pole from scattering data below the threshold, including the new precise results obtained from decay by NA48/2…
On the determination of from experimental data on the isoscalar -wave at low energies
Irinel Caprini
We investigate the determination of the pole associated to from scattering data below the threshold, including the new precise data from decay reported…
Comment on "Infrared freezing of Euclidean QCD observables"
Irinel Caprini, Jan Fischer
Recently, P. M. Brooks and C.J. Maxwell [Phys. Rev. D{\bf 74} 065012 (2006)] claimed that the Landau pole of the one-loop coupling at is absent from the leading one-chain…
Infrared freezing of Euclidean observables and analyticity in perturbative QCD
Irinel Caprini, Jan Fischer
The renormalization-group improved finite order expansions of the QCD observables have an unphysical singularity in the Euclidean region, due to the Landau pole of the running coup…
