“…Various processes could be used to study these hyperon resonances. The neutrino induced hyperon production processes νe/µ + p → e + /µ + + π + Λ/Σ may provide a unique clean place for studying low energy πΛ/Σ interaction and hyperon resonances below KN threshold [36].…”

Quenched and unquenched quark models predict very different patterns for the spectrum of the low excited hyperon states. Evidence is accumulating for the existence of some new hyperon resonances, such as a Σ * of spin-parity J P = 1/2 − around 1400 MeV instead of 1620 MeV as listed in PDG, a new Σ(1540)3/2 − resonance, a new narrow Λ(1670)3/2 − resonance and a new Λ(1680)3/2 + resonance. All these new hyperon resonances fit in the predicted pattern of the unquenched quark models very well. It is extremely important to check and establish the spectrum of these low excited hyperon states by the proposed K L beam experiments at JLAB.

“…The symmetries of the weak hadronic current like the T-invariance, G-invariance and SU(3) symmetry can also be tested, and some information on the physics beyond the standard model may also be obtained. In the past, various calculations on the charged current induced (anti)neutrino and electron scattering from the free nucleon and nuclear targets, have been done by many authors in which both the production cross sections as well as the polarization observables of muons and baryons were studied [3][4][5][8][9][10][11][12][13][14][15][16]. With the advancement in the detection technology and the observation of the τ neutrino (ν τ ) experimentally, some calculations for the polarization observables of the τ leptons produced in the ν τ (ν τ ) induced reactions have also been performed in the weak processes [12,[17][18][19][20][21][22].…”

The quasielastic production cross sections and polarizations of the hyperons induced by νµ on the free nucleon as well as from 40 Ar in the sub-GeV energy region has been reviewed [1][2][3][4][5]. The effects of the second class currents in the axial vector sector with and without T-invariance as well as the effect of SU(3) symmetry breaking are also studied. We find that the cross sections and the various polarization components can effectively be used to determine the axial vector transition form factors in the strangeness sector and to test the validity of various symmetries of the weak hadronic currents like G-invariance, T-invariance and SU(3) symmetry. These hyperons decay dominantly into pions giving an additional contribution to the weak pion production induced by the antineutrinos. In the case of nuclear targets like 40 Ar, this contribution is shown to be significant when compared with the the pion production by the ∆ excitations in the energy range of Eν µ ≤ 0.7 GeV [1]. This study could be useful for the DUNE experiment where argon will be used as the target material and the electronic imaging of particles is possible and the particle tracks can be identified.

“…In last decade there were several attempts to explore the strangeness physics in weak sector [1,2]. The quasielastic production of hyperons [3][4][5][6] and their subsequent decay into pions [7,8] have been recently analyzed around ∼ 1 GeV anti-neutrino energies. Experimental efforts are also made to observe such processes [9].…”

The charged current Cabibbo-supressed associated KΞ production off the nucleon induced by anti-neutrinos is studied at low and intermediate energies. The non-resonant terms are obtained using a microscopical model based on the SU(3) chiral Lagrangian. The basic parameters of the model are fπ, the pion decay constant, Cabibbo's angle, the proton and neutron magnetic moments and the axial vector coupling constants for the baryons octet, D and F, that are obtained from the analysis of the semileptonic decays of neutron and hyperons. In addition, we also consider Σ * (1385) resonance, which can decay in KΞ final state when this channel is open. The studied mechanism is the prime source of Ξ production at anti-neutrino energies around 2 GeV and the calculated cross sections at these energies can be measured at the current and future neutrino experiments. * rafi.alam.amu@gmail.com † ruizsig@ugr.es 1 |∆S| = 2 processes are highly suppressed.
