Search for Exclusive Multi-Body Non-DbarD Decays at the psi(3770)

TL;DR

This study searched for rare charmless multibody decays of the psi(3770) resonance using CLEO-c data but found no evidence of such decays, setting constraints on their occurrence.

Contribution

First comprehensive search for 25 charmless multibody decay modes of psi(3770) with no observed signals, providing new limits on these decay processes.

Findings

No evidence of charmless multibody decays

Set upper limits on decay branching fractions

Contributes to understanding psi(3770) decay mechanisms

Abstract

Using data collected at the psi(3770) resonance with the CLEO-c detector at the Cornell e^+e^- storage ring, we present searches for 25 charmless decay modes of the psi(3770), mostly multibody final states. No evidence for charmless decays is found.
