An Approximate Phase Shift Analysis of N Scattering

Phase shift analysis of 0-30 MeV pp scattering data.

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

The Use of the Scattering Phase Shift in Resonance Physics

The scattering phase shift encodes a good amount of physical information which can be used to study resonances from scattering data. Among others, it can be used to calculate the continuum density of states and the collision time in a resonant process. Whereas the first information can be employed to examine the evolution of unstable states directly from scattering data, the second one serves a...

Phase shift of isospin-2 scattering from lattice QCD

Finite-volume lattice QCD calculations offer the possibility of extracting resonance parameters from the energy-dependent elastic phase-shift computed using the Lüscher technique. In this letter, as a trial of the method, we report on the extraction of the nonresonant phase-shift for S and D-wave isospin-2 scattering from dynamical lattice QCD computations. We define a variational basis of oper...
