W3-7 Mesons I (DNP) / Mésons I (DPN)
- Mark McCrea (University of Winnipeg)
The GlueX Experiment at Jefferson Lab has been collecting high-energy photoproduction data since 2016 as part of its search for hybrid mesons, mesons in which the
gluonic field has been excited. An over views of the GlueX experiment and its physics program, including first results and the ongoing searches for hybrids will be presented.
These results include studies of photoproduction...
The primary goal of the GlueX program is to explore the spectrum of light-quark mesons for excitations with explicit gluonic degrees of freedom, as predicted by Quantum Chromodynamics. These particles are termed hybrid mesons and some are predicted to possess exotic JPC quantum numbers. Lattice QCD predicts patterns of hybrid states with masses in the 2-GeV/c^2 range, which can be accessed in...
The Kaon LT experiment (E12-09-011) at Jefferson Lab, USA was designed to study the LT separated cross-section of the reaction $^1H(e, e'K^+ )Λ / Σ^0$ and to attempt to extract the $K^+$ electromagnetic form factor. The measurements for the $K^+$ electromagnetic form factor are important, as they allow us to better understand the role of the strange quark ($s$) in the $K^+$ structure. This...
