Our group has a new result using the Generalized Contact Formalism, which has proved so successful in describing short-range correlations between nucleons. MIT graduate student Jackson Pybus, performed calculations corresponding to a measurement made in 2011 in Hall A of Jefferson Lab of the triple-coincidence (e,e’pN) reaction on a helium-4 target. The GCF calculations match the experimental measurements without any free parameters, and further confirm the acceptance corrections made in the original analysis. This is one more example of GCF proving effective at describing the electron-induced knock-out of correlated nucleons, following previous results in PRL and in Nature on carbon.
I’ve been fortunate to work with Jackson on a number of projects starting when I was a postdoc at MIT, and I’m thrilled that we’ve continued to collaborate since I’ve come to GW.
