16 Oct 2012 | Abstract: | The primary motivation of the GlueX experiment is to search for and
ultimately study the pattern of gluonic excitations in the meson spectrum
produced in gamma p collisions. Recent lattice QCD calculations predict a rich
spectrum of hybrid mesons that have both exotic and non-exotic JPC,
corresponding to q q-bar (q=u, d, or s) states coupled with a gluonic field. A
thorough study of the hybrid spectrum, including the identification of the
isovector triplet, with charges 0 and +-1, and both isoscalar members, |s
s-bar> and |u u-bar> + |d d-bar>, for each predicted hybrid combination of JPC,
may only be achieved by conducting a systematic amplitude analysis of many
different hadronic final states. We propose the development of a kaon
identification system, supplementing the existing GlueX forward time-of-flight
detector, in order to cleanly select meson and baryon decay channels that
include kaons. Once this detector has been installed and commissioned, we plan
to collect a total of 200 days of physics analysis data at an average intensity
of 5 x 10^7 tagged photons on target per second. This data sample will provide
an order of magnitude statistical improvement over the initial GlueX data set
and, with the developed kaon identification system, a significant increase in
the potential for GlueX to make key experimental advances in our knowledge of
hybrid mesons and Cascade baryons. | Source: | arXiv, 1210.4508 | Services: | Forum | Review | PDF | Favorites |
