摘要
The excitation of two-particle-two-hole final states in neutrino-nucleus scattering has been advocated by many authors as the source of the excess cross section observed by the MiniBooNE Collaboration in the quasielastic sector. We analyze the mechanisms leading to the appearance of these final states and illustrate their significance through the results of accurate calculations of the nuclear electromagnetic response in the transverse channel. A novel approach, allowing for a consistent treatment of the amplitudes involving one-and two-nucleon currents in the kinematical region in which the nonrelativistic approximation breaks down, is outlined, and its preliminary results are reported.
