We use chiral effective field theory (χEFT) to make predictions for the longitudinal electromagnetic response function of the deuteron, f L , which is measured in d(e, e ′ N ) reactions. In this case the impulse approximation gives the full χEFT result up to corrections that are of O(P 4 ) relative to leading order. By varying the cutoff in the χEFT calculation between 0.6 and 1 GeV we conclude that the calculation is accurate to better than 10% for values of q 2 within 4 fm −2 of the quasi-free peak, up to final-state energies E np = 60 MeV. In these regions χEFT is in reasonable agreement with predictions for f L obtained using the Bonn potential. We also find good agreement with existing experimental data on f L , albeit in a more restricted kinematic domain.

Deuteron photodisintegration, three-body photodisintegration of 3 He as well as muon capture on the deuteron and 3 He are theoretically analyzed by means of improved chiral nucleon-nucleon interactions. To this end we solve the Schrödinger and Faddeev equations in the momentum space. While our electromagnetic current operator implicitly receives implicitly many-body contributions via the Siegert theorem, the weak current is taken in the form of the nonrelativistic single nucleon current supplemented by the dominant relativistic corrections. Such models of the current operators and the wave functions generated with the new chiral potentials lead to reasonable predictions for the cross sections and capture rates studied in this contribution. Our results show very welcome features of the new forces and prove their usefulness in studies of electroweak processes with few nucleons.
