dc.description.abstract | We present a fast and efficient method to compute the inclusive two-particle two-hole (2p–2h)
electroweak responses in the neutrino and electron quasielastic inclusive cross sections. The method is
based on two approximations. The first neglects the motion of the two initial nucleons below the Fermi
momentum, which are considered to be at rest. This approximation, which is reasonable for high values
of the momentum transfer, turns out also to be quite good for moderate values of the momentum transfer
q kF . The second approximation involves using in the “frozen” meson-exchange currents (MEC) an
effective -propagator averaged over the Fermi sea. Within the resulting “frozen nucleon approximation”,
the inclusive 2p–2h responses are accurately calculated with only a one-dimensional integral over the
emission angle of one of the final nucleons, thus drastically simplifying the calculation and reducing the
computational time. The latter makes this method especially well-suited for implementation in Monte
Carlo neutrino event generators. | es |
