“…In this section, we first present a review of the old experimental results on the total cross sections and their Q 2 dependence in the case of hyperon production from CERN on Freon [60] and Propane [59,61], FNAL on Neon [63,64], SKAT on Freon [65] and BNL on H 2 [62] and compare them with the theoretical results. We also present the experimental results on the Lambda hyperon polarizations from CERN [61] and compare them with the most recent theoretical calculations [82].…”

“…In this work, we have presented a review of the theoretical and experimental work done on the quasielatic production of hyperons induced by antineutrinos which was started more than 50 years ago soon after the V − A theory of weak interactions was extended to the strangeness sector by Cabibbo [41] using SU(3) symmetry properties of the weak hadronic currents. The experimental results on the total cross sections and their Q 2 dependence available from the older experiments at CERN [59][60][61], FNAL [63,64], SKAT [65] and BNL [62] and the results on Lambda hyperon polarizations from CERN [61] are compared with the most recent theoretical results [81,82].…”

“…In order to compare with the experimental results of CERN experiment [61], we have performed the numerical calculations for the flux averaged cross section σ , longitudinal P L and perpendicular P P polarization components relevant for the antineutrino flux of SPS antineutrino beam of Gargamelle experiment at CERN [99] and present our results in Table-II. The results are compared with the available experimental results from CERN [59][60][61] experiment and the theoretical results quoted by Erriquez et al [61].…”

“…It is for this reason that the work in the quasielastic production of hyperons induced by the antineutrino was started more than 50 years back and many theoretical papers have reported results for the cross section and the polarization of the hyperons in the literature which have been summarized in the early works of Marshak et al [56], Llewellyn Smith [57] and Pais [58]. Experimentally, however, there are very few attempts made where the quasielastic production of Λ, Σ 0 , Σ − have been studied, like at CERN [59][60][61], BNL [62], FNAL [63,64] and SKAT [65]. A summary of all the experimental results on the energy dependence of the total cross sections on the hyperon production and its comparison with the theoretical calculations has been given by Kuzmin and Naumov [66] and Rafi Alam et al [67].…”

“…σ(ν µ p → µ + Σ 0 ) = 1 2 σ(ν µ n → µ + Σ − ), while no Σ + is produced off the free nucleon target due to ∆S = ∆Q rule. A comparison is made with available experimental results from CERN [59][60][61], BNL [62], FNAL [63,64] and SKAT [65] experiments as well as with the theoretical calculations performed by Wu et al [86] and Finjord and Ravndal [55] using quark model and the calculations performed by Erriquez et al [61], Brunner et al [65] and Kuzmin and Naumov [70] based on the prediction from Cabibbo theory. A reasonable agreement with the experimental results can be seen.…”

Weak Quasielastic Hyperon Production Leading to Pions in the Antineutrino-Nucleus Reactions

In this review, we have studied the quasielastic production cross sections and polarization components of Λ, Σ 0 and Σ − hyperons induced by the weak charged currents in the antineutrino reactions on the nucleon and the nuclear targets like 12 C, 16 O, 40 Ar and 208 Pb. It is shown that the energy and the Q 2 dependence of the cross sections and the various polarization components can be effectively used to determine the axial vector transition form factors in the strangeness sector and test the validity of various symmetry properties of the weak hadronic currents like G-invariance, T-invariance and SU(3) symmetry. In particular, the energy and the Q 2 dependence of the polarization components of the hyperons is found to be sensitive enough to determine the presence of the second class current with or without T-invariance.These hyperons decay dominantly into pions giving an additional contribution to the weak pion production induced by the antineutrinos. This contribution is shown to be quantitatively significant as compared to the pion production by the ∆ excitation in the nuclear targets in the sub-GeV energy region relevant for theνµ cross section measurements in the oscillation experiments. We have also included a few new results, based on our earlier works, which are in the kinematic region of the present and future (anti)neutrino experiments being done with the accelerator (anti)neutrinos at T2K, MicroBooNE, MiniBooNE, NOνA, MINERνA and DUNE, as well as for the atmospheric (anti)neutrino experiments in this energy region.
