JLab E12-17-003 (nnΛ experiment)

Overview

This experiment searches for the either resonance or bound nnΛ state through the ³H(e,e'K⁺)nnΛ reaction at JLab Hall A.
The experiment is scheduled to perform from Oct 22 to Nov 11, 2018. HYP_HRS-HKS

Experimental setup

We will use the two arms of HRSs in JLab Hall A.
The beam at E_e = 4.3 GeV will be incident on a gaseous tritium target with a thickness of about 80 mg/cm²,
and scattered electrons and K⁺s with central momenta of 2.2 and 1.8 GeV/c will be measured by HRSs in coincidence at θ_K = θ_e' = 13.2 degrees.
