Pion Scattering Length from Two - Pion Wave Function ∗
We present a preliminary report on a calculation of scattering length for I = 2 S-wave two-pion system directly from the two-pion wave function. Results are compared with those calculated from the time dependence of twopion four-point functions. Calculations are made with an RG-improved action for gluons and improved Wilson action for quarks at a−1 = 1.207(12) GeV on 20 × 48 and 24 × 48 lattices.

متن کاملPhase-Shift Definition for Pion-Nucleon Scattering from Chiral Perturbation Theory
Chiral Perturbation Theory is considered as a very precise method when applied to pion-nucleon scattering near threshold and in the unphysical region since in these cases the pion momenta are small. In this framework, third order calculation yields a non-relativistic scattering amplitude with nine free parameters. From the fact that the resulting partial-wave amplitudes do not respect elastic u...
متن کاملPion - Pion Scattering Information
We show how the reaction e-e’+ n-n’y can be used to study the dipion system in states of even charge conjugation (and even angular momentum). In particular, its utility for experimentally investigating an I = 0, J = 0 resonance (e-meson) is discussed in detail. (Submitted to Phys. Rev. ) * Work supported by the U. S.

متن کاملPion-pion Scattering above Resonances
We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at |t| ∼ 1 GeV, but the pQCD exchange dominance is deferred to |t| ∼ 3 GeV because of competing multiple soft rescattering effects. Base...
