A three-Nucleon SRC (3N-SRC) is a trio of nucleons with large individual momenta ( | p → 1 |,| p → 2 |,| p → 3 | ) and small total (or c.m.) momentum ( p → c.m. = p → 1 + p → 2 + p → 3 ), where large and small are measured relative to the Fermi momentum of nucleons in the nucleus.

The goals of this work are:

Identify ppp-SRC candidates using a sample of A(e,e'p) events selected to maximize the number of SRC nucleons.

Characterize the topology of ppp-SRC events .

Extract the ratio of of ppp-SRC to one-proton knockout events, in order to determine the probability to find a ppp-SRC event in the nucleus.

A brief description of the under-going analysis will be presented.
