Proposal for JLab PAC 45 PR 12 – 17 – 001 Strange Hadron Spectroscopy with a Secondary K L Beam at GlueX

We propose to create a secondary beam of neutral kaons in Hall D at Jefferson Lab to be used with the GlueX experimental setup for strange hadron spectroscopy. A flux on the order of 3×10 KL/s will allow a broad range of measurements to be made by improving the statistics of previous data obtained on hydrogen targets by three orders of magnitude. Use of a deuteron target will provide first measurements on the neutron which is terra incognita. The experiment will measure both differential cross sections and self-analyzed polarizations of the produced Λ, Σ, Ξ, and Ω hyperons using the GlueX detector at the Jefferson Lab Hall D. The measurements will span c.m. cos θ from −0.95 to 0.95 in the c.m. range above W = 1490 MeV and up to 3500 MeV. These new GlueX data will greatly constrain partial-wave analyses and reduce model-dependent uncertainties in the extraction of strange resonance properties (including pole positions), and provide a new benchmark for comparisons with QCD-inspired models and lattice QCD calculations. The proposed facility will also have an impact in the strange meson sector by providing measurements of the final-state Kπ system from threshold up to 2 GeV invariant mass to establish and improve on the pole positions and widths of all K∗(Kπ) P-wave states as well as for the S-wave scalar meson κ(800).
