Search for Exotic Mesons in pi- P Interactions at 18 GeV/c

TL;DR

This paper reports on a search for exotic mesons in pion-proton interactions at 18 GeV/c, focusing on decay modes that could indicate non-quark-antiquark states.

Contribution

It summarizes recent experimental efforts to identify non-$q ar{q}$ mesons through various decay channels in high-energy pion-proton collisions.

Findings

Investigation of multiple decay modes for exotic mesons.

Analysis of data from Brookhaven National Laboratory.

Ongoing search for non-standard meson states.

Abstract

The recent search for non $q \bar{q}$ mesons in $\pi^{-}p$ interactions at Brookhaven National Laboratory is summarized. Many final states such as $\eta \pi$, $\eta' \pi^{-}$, $a_{0} \pi$, $f_{1} \pi$, $a_{2} \pi$, $b_{1} \pi$, which are favored decay modes of exotics, are under investigation.
