dc.description.abstractWe consider the 7r7r-scattering problem in the context of the Kadyshevsky equation. In this scheme, we introduce a momentum grid and provide an isospectral definition of the phase shift based on the spectral shift of a Chebyshev angle. We address the problem of the unnatural high momentum tails present in the fitted interactions which reaches energies far beyond the maximal center-of-mass energy of root s = 1.4 GeV. It turns out that these tails can be integrated out by using a block-diagonal generator of the SRG.es_ES
