Exotic Mesons at JLab Before 2013? The Search for New Forms of Matter at CLAS

摘要

A proposal to search for exotic mesons in photoproduction has been accepted for running at Thomas Jefferson National Accelerator Facility, using the CEBAF Large Acceptance Spectrometer in Hall B. This program will bolster previously-thin statistics in many photoproduction channels, primarily those with charged particles in the final state, as well as seeking to confirm earlier findings in neutral channels, if possible. The promise of the neutral 3 channel is discussed. In addition, the experiment seeks to study the spectrum of both exotic and ordinary strangeonia. Limitations of the CLAS detector for meson spectroscopy are discussed, as well as possible solutions to minimize such limitations.
