Quasielastic Neutrino Scattering

Neutrino-Nucleus Interactions

“…Some illumination regarding the possibility that the observed "quasi elastic" cross section exceed that for free nucleons can be found in an interesting calculation of the longitudinal and transverse response functions for QEES from 3 He and 4 He. This calculation is carried out in the framework of Euclidian Response Functions (32,77).…”

“…Proton recoil energies up to 1.8 GeV have been examined in (83). Ongoing studies at Jefferson Laboratory (84) in e- 3 He scattering finds that the unfolding of initial and final state interactions is more complicated in collisions where short range correlations are involved. This will likely be the case for many of the events occurring in neutrino-nucleus scattering.…”

“…A simple version of scaling sufficient for this review is presented below but there are many further refinements in the literature (32). Figure 3a shows the inclusive electron scattering cross section off 3 He at differing incident energies and scattering angles. The greatly varying values of the cross sections can be related by employing a scaling variable y, related to the scaling variable x=Q 2 /2Mω used in deep inelastic scattering.…”

“…The motivation for investigating 3 He and 4 He was the large change of the ratio of transverse to longitudinal response in observed in QEES. The larger size of the transverse yield occurs even at ψ'=0, making it unlikely that it is due to the tail of the Δ resonance.…”

Quasielastic axial-vector mass from experiments on neutrino–nucleus scattering

“…In this study, which is in a sense complementary to that by Bodek et al [3], we attempt to extract the axial mass value by a global statistical analysis of all available consistent data on the total and differential QES cross sections measured in accelerator experiments with ν µ and ν µ beams 1 from ANL [12][13][14][15][16][17][18][19], BNL [20][21][22][23][24][25][26][27][28][29][30][31][32][33], FNAL [34][35][36][37][38][39][40], CERN , and IHEP [65][66][67][68][69][70][71][72][73][74]. The detector media used in these experiments are hydrogen, deuterium, carbon, aluminium, argon, iron/steel, propane, freon, and also propane-freon and neon-hydrogen mixtures.…”
