Charged and neutral pion production in the S-matrix approach
V. Malafaia, M. T. Pena, Ch. Elster +1
The S-matrix approach is used to calculate charged as well as neutral pion production reactions from NN scattering, with the same set of underlying processes and interactions. The…
Neutral and charged pion production in the S-matrix approach
V. Malafaia, M. T. Pena, J. Adam
The S-matrix approach is applied to charged and neutral pion production in pp collisions, in which the spin/isospin channels filter differently the rescattering mechanism. The chir…
Pion re-scattering operator in the S-matrix approach
V. Malafaia, J. Adam, M. T. Pena
The pion re-scattering operator for pion production, derived recently in time-ordered perturbation theory, is compared with the one following from the simple S-matrix construction.…
Pion re-scattering in pi0 production
V. Malafaia, M. T. Pena
This work discusses the approximations frequently used to calculate the contribution to pion production in proton-proton scattering near threshold from irreducible pion re-scatteri…
Pion re-scattering in pi0 production near threshold
V. Malafaia, M. T. Pena
We compare the most used approximations to calculate the contribution from pion re-scattering mechanisms to pion production from proton-proton scattering, near threshold. Our calcu…
