Analytical dispersive parametrization for elastic scattering of spinless particles

HIGHLIGHTS

• who: Igor Danilkin and colleagues from the Institut, Mainz, Germany have published the paper: Analytical dispersive parametrization for elastic scattering of spinless particles, in the Journal: (JOURNAL) of 19/04/2023
• what: In the derivation of the dispersive parametrization for the higher partial waves, the authors implement the angular momentum barrier factor as a relevant kinematic constraint. In Sec V the authors show some numerical test cases, with the emphasis on the recent lattice data on the S-wave isoscalar u03c0u03c0 u2192 u03c0u03c0 scattering (mu03c0=239 MeV1) from the HadSpec collaboration . In case of nonequal . . .
