Abstract
The excitation of two particle-two hole final states in neutrino-nucleus scattering, not taken into account in Monte Carlo simulations for data analysis, has been advocated by many authors as the source of the excess cross section observed by the MiniBooNE collaboration in the quasi elastic channel. We analyse the mechanisms leading to the appearance of two particle-two hole states, and show that interference between the amplitudes involving one- and two-nucleon currents, not consistently included in existing calculations, plays a major role. A novel approach allowing to treat one- and two-nucleon current contributions on the same footing is outlined.
