With extremely high precision in energy measurement, researchers anticipated to study the change of appearance of the baryon identities, i.e. quark freedom. Led by Hampton University, research groups including 80 scientists from 14 different institute and five countries, has designed and built a state of art high precision magnetic spectrometer system to carry out a high precision experiment in Hall C at Jlab using the highly accurate and powerful electron beam. We have observed directly a splitting pair states with a Lambda hyperon resided in p-shell orbit in the nucleus. The first such study using electron beam. Due to the features of electromagnetic process, entirely new spectroscopy was observed.
Data is very valuable.
The first experiment which can handle extremely high background rate at Jlab. The first large scale experiment ever run and led by a HBCU and demonstrated the strength we have in Hampton University and made Hampton University noticed world wide. The data is still under analysis by HU graduate students and the result will be submitted soon to Phys. Rev. Lett. for publication. Improve resolution by another factor of two.
