Description
The KLong Experiment in Jefferson Lab Hall D will use a secondary beam of neutral kaons and the GlueX experimental setup to perform strange hadron spectroscopy. By achieving a flux on the order of $1×10^{4}$ $K_{L}$/sec, KLF will allow a broad range of measurements that improve the statistics of previous world data by several orders of magnitude.
The experiment will measure both differential cross sections and self-analysed polarisations of the produced $\Lambda$, $\Sigma$, $\Xi$ and $\Omega$ hyperons spanning the mass range W = 1490 MeV to 2500 MeV. KLF data will significantly constrain partial wave analyses and reduce model-dependent uncertainties in the extraction of the properties and pole positions of the strange hyperon resonances, as well as establish the orbitally excited multiplets in the spectra of the $\Xi$ and $\Omega$ hyperons. The proposed facility will also explore the strange meson sector through measurements of the final state $K\pi$ system up to 2 GeV invariant mass, and with the addition of nuclear emulsion detectors for high-resolution tracking, contribute to studies of hypernuclei.
This talk will give an overview of the KLong Facility design, current status, and prospects for its impact in strangeness spectroscopy.
