TL;DR

This paper investigates how the pbar d to D Dbar N reaction can be used to study DN and DbarN interactions by analyzing meson rescattering processes in antiproton-deuteron collisions.

Contribution

It introduces methods to extract DN and DbarN interaction information from rescattering effects in antiproton-deuteron reactions.

Findings

Identified strategies to isolate D^0p and D^-p rescattering contributions.

Proposed a framework for studying open-charm meson interactions.

Enhanced understanding of meson-nucleon rescattering mechanisms.

Abstract

We examine the possibility to extract information about the DN and DbarN interactions from the pbar d to D Dbar N reaction. We utilize the notion that the open-charm mesons are first produced in the annihilation of the antiproton on one nucleon in the deuteron and subsequently rescatter on the other (the spectator) nucleon. The latter process is then exploited for investigating the DN and DbarN interactions. We study different methods for isolating the contributions from the D^0p and D^-p rescattering terms.
