Effects of Relativistic Dynamics in pp − → ppπ 0 near Threshold
نویسندگان
چکیده
The cross-section for threshold π0 production in proton-proton collisions is evaluated in the framework of the covariant spectator description. The negative energy intermediate states are included non-perturbatively and seen to yield a considerably smaller contribution, when compared to perturbative treatments. A family of OBE-models with different off-shell scalar coupling is considered. Typeset using REVTEX

Chiral perturbation approach to the pp-->pp pi 0 reaction near threshold.
The usual theoretical treatments of the near-threshold pp → ppπ 0 reaction are based on various phenomenological Lagrangians. In this work we examine the relationship between these approaches and a systematic chiral perturbation method. Our chiral perturbation calculation indicates that the pion rescattering term should be significantly enhanced as compared with the traditional phenomenological...

Due to isospin suppression of the otherwise dominant low-energy isovector WeinbergTomosawa πN term in the re-scattering diagram, and the negative interference between the remaining impulse and isoscalar pion re-scattering terms[1], the empirical data for pp → ppπ near threshold is only explained by phenomenological non-pionic, short-range, twobody mechanisms[2], or alternatively by an off-shell...

The role of the low lying nucleon resonances beyond the ∆(1232) in the reaction pp → ppπ 0 near threshold is shown to be numerically significant by a calculation, which takes into account the pion re-scattering contribution described by chiral perturbation theory and the short-range mechanisms that are implied by the nucleon-nucleon interaction model. The intermediate N (1440) (P 11) resonance ...

We present a systematic analysis of next-to-next-to-leading-order diagrams that contribute to the pp → ppπ 0 production at threshold. Analytic expressions are given for the effective transition operators, and the relative importance of various types of diagrams is discussed. The vertex-correction-type graphs are found to give only small corrections to lower order graphs in conformity with expec...
