Final stare interaction enhancement effect on the near threshold p\bar p system in B^\pm\to p\bar p \p^\pm decay

TL;DR

This paper investigates the low-mass enhancement in baryon-antibaryon pairs from B meson decays, demonstrating that final state interactions modeled by Regge theory can explain the observed mass spectrum.

Contribution

It introduces a Regge theory-based model of final state interactions to explain the near-threshold enhancement in baryonic B decays.

Findings

Rescattering effects reproduce the observed mass spectrum.

Final state interactions significantly influence baryon-antibaryon invariant mass distributions.

The model aligns well with experimental data.

Abstract

We discuss the low-mass enhancement effect in the baryon-antibaryon invariant mass in three-body baryonic B decays using final state interactions in the framework of Regge theory. We show that the rescattering between baryonic pair can reproduce the observed mass spectrum.
