Determining the unknown Λ-n interaction by investigating the Λnn resonance


  • Bishnu PANDEY

We carried out the experiment E12-17-003 at Jefferson Lab in November 2018 by using the 3H(e,e’K+)Λnn reaction with the high quality CEBAF electron beam and the Hall A high resolution spectrometers. The goal of the experiment is to search for the possible Λnn three-body resonance. If such a resonance exists, it may provide, for the first time, experimental information that can be used to determine the unknown Λn interaction relative to the Λp interaction fitted from limited Λp scattering data. This can help to address the long existing puzzle of Charge-symmetry-breaking (CSB) in ΛN interactions.
