Studies of three-nucleon short-range correlations in the mirror nuclei 3H and 3He

The hard, short-range interactions between nucleons in dense nuclei is the primary source of high-momentum nucleons. These are dominantly in the form of two-nucleon short-range correlations (2N-SRCs), and the JLab program has made great progress in quantifying their contributions to nuclei and in mapping out their momentum and isospin dependence. Similar three-nucleon configurations are expected to be important at even higher momenta but, as yet, there is not a clear demonstration of 3N-SRC dominance. I will briefly summarize the state of 3N-SRC searches, and then focus on the results of 3N-SRC studies in the mirror nuclei 3H and 3He. These nuclei provide several advantages when trying to study the structure of 3N-SRCs, and are already able to provide constraints on the momentum and isospin structure of these rare parts of the nuclear wavefunction.
