18.22} Neutrino interactions


 Quasi Elastic neutrino interactions have been implemented in FLUKA in
 1997. Between 1998 and 2008, an interface to an external neutrino
 generator has been used, although not distributed. This interface was
 embedded into the PEANUT model, and allowed interesting studies of
 nuclear effects in neutrino interactions.

 In 2008, a new generator for neutrino interactions on nucleons and
 nuclei has been developed and implemented in FLUKA. The
 neutrino-nucleon event generator handles Deep Inelastic Scattering
 (NUNDIS, mainly developed by Mattias Lantz) and production of delta
 resonances (NUNRES). Hadronisation after DIS is handled by the same
 hadronisation model used in hadron-hadron interactions.  NUNDIS and
 NUNRES are embedded in PEANUT to simulate neutrino-nucleus reactions.
