Possible explanation of Hoehler's clustering: effective partial-wave mixing induced by truncation
A. Svarc
Hoehler noted that resonance poles obtained from different partial waves in scattering appear to bunch together near a small set of common complex energies, and suggested that…
Resonances extracted in truncated partial-wave analysis are effective mixtures of angular momenta (Possible implications for Höhler's clustering)
A. Švarc
In truncated partial-wave analysis one fits observables, not amplitudes, and the relevant observables are bilinear in the amplitudes. For angle-dependent observables from which par…
Single-channel, single-energy partial-wave analysis with continuity improved through minimal phase constraints
A. Svarc, R. L. Workman
Single-energy partial-wave analysis has often been applied as a way to fit data with minimal model dependence. However, remaining unconstrained, partial waves at neighboring energi…
Towards an understanding of discrete ambiguities in truncated partial wave analyses
Y. Wunderlich, A. Švarc, R. L. Workman +2
It is well known that the observables in a single-channel scattering problem remain invariant once the amplitude is multiplied by an overall energy- and angle-dependent phase. This…
