“…The study of SIS region is also important in the neutrino/antineutrino experiments being performed in the few GeV energy region. Almost all the neutrino/antineutrino experiments are using moderate to heavy nuclear targets like 12 C, 16 O, 40 Ar, 56 F e and 208 P b. There is a dedicated experiment presently running at the Fermi lab (MINERvA) [12], where the nuclear medium effects are being studied using several nuclear targets in the ν l /ν l −nucleus scattering, as well as there is plan to study NME in 40 Ar in the proposed DUNE experiment at the Fermi lab [14,15].…”

“…Dashed-dotted line is the result for the spectral function only obtained using the phenomenological parameterization[44] of HT effect at NLO. F2A(x, Q 2 ) (A = 12 C,27 Al,56 F e, 118 Sn, 197 Au and 208 P b) vs x are shown at Q 2 = 3 GeV 2 . The results are obtained at NNLO using spectral function only (dashed-double dotted line), spectral function with shadowing effect (dashed line) and with the full model (solid line).…”

The results are obtained for the full model with HT effect (renormalon approach) using MMHT nucleonic PDFs and pionic PDFs of (i) Gluck et al[48] (dotted line), (ii) Wijesooriya et al[49] (dashed-double dotted line) at NLO.…”

We have studied the nucleon structure functions F EM iN (x, Q 2 ); i = 1, 2, by including contributions due to the higher order perturbative QCD effect up to NNLO and the non-perturbative effects due to the kinematical and dynamical higher twist (HT) effects. The numerical results for F EM iN (x, Q 2 ) are obtained using Martin, Motylinski, Harland-Lang, Thorne (MMHT) 2014 NLO and NNLO nucleon parton distribution functions (PDFs). The dynamical HT correction has been included following the renormalon approach as well as the phenomenological approach and the kinematical HT effect is incorporated using the works of Schienbein et al. These nucleon structure functions have been used as an input to calculate the nuclear structure functions F EM iA (x, Q 2 ). In a nucleus, the nuclear corrections arise because of the Fermi motion, binding energy, nucleon correlations, mesonic contribution, shadowing and antishadowing effects. These nuclear corrections are taken into account in the numerical calculations to obtain the nuclear structure functions F EM iA (x, Q 2 ), for the various nuclear targets like 12 C, 27 Al, 56 F e, 64 Cu, 118 Sn, 197 Au and 208 P b which are of experimental interest. The effect of isoscalarity correction for nonisoscalar nuclear targets has also been studied. The results for the F EM iA (x, Q 2 ) are compared with nCTEQ nuclear PDFs parameterization as well as with the experimental results from JLab, SLAC and NMC in the kinematic region of 0.1 ≤ x ≤ 0.8 for several nuclei. We have also calculated the ratio RA(x, Q 2 ) = F 2A (x,Q 2 ) 2xF 1A (x,Q 2 ) in the moderate Q 2 region for various nuclei and compared the results with the available experimental data from JLab to examine the validity of Callan-Gross relation in the nuclei. We also make predictions for the nuclear structure functions in 12 C, 64 Cu and 197 Au in the kinematic region of the proposed experiment at the JLab.

“…Our numerical results are compared with the available JLab data [18] and also with the available results from earlier experiments performed by NMC [12] collaboration. This study is a continuation of our previous study of nuclear medium effects in the extraction of electromagnetic and weak structure functions 58,60], Paschos-Wolfenstein relation [61] and Parity Violating asymmetry in deep inelastic polarized electron scattering [62] from nuclear targets. In the present paper, we have obtained the expressions of F A 1 N (x, Q 2 ) and F A 2 N (x, Q 2 ) separately without using the Callan-Gross relation.…”

Recent experiments performed on inclusive electron scattering from nuclear targets have measured the nucleon electromagnetic structure functions F1(x, Q 2 ), F2(x, Q 2 ) and FL(x, Q 2 ) in 12 C, 27 Al, 56 F e and 64 Cu nuclei. The measurements have been done in the energy region of 1 GeV 2 < W 2 < 4 GeV 2 and Q 2 region of 0.5 GeV 2 < Q 2 < 4.5 GeV 2 . We have calculated nuclear medium effects in these structure functions arising due to the Fermi motion, binding energy, nucleon correlations, mesonic contributions from pion and rho mesons and shadowing effects. The calculations are performed in a local density approximation using a relativistic nucleon spectral function which includes nucleon correlations. The numerical results are compared with the recent experimental data from JLab and also with some earlier experiments.

“…In the local-density approximation the nuclear hadronic tensor W ν(ν)A αβ can be written as a convolution of the nucleonic hadronic tensor with the hole spectral function. For a N =Z nucleus like 56 F e, we have considered separate distributions of Fermi sea for protons and neutrons [4]:…”

We have studied nonisoscalarity and medium effects in the extraction of weak mixing angle using Paschos and Wolfenstein relation in the iron nucleus. Paschos and Wolfenstein(PW) relation is valid for an isoscalar target. We have modified the PW relation for nonisoscalar target as well as incorporated the medium effects like Pauli blocking, Fermi motion, nuclear binding energy and pion rho cloud contributions. In our calculations we have used the relativistic nuclear spectral function which includes nucleon correlations.Finally local density approximation is applied to translate the numerical results to the finite nuclei. We have studied the dependence of sin 2 θ W on Bjorken variables x and y, four momentum transfer square (Q 2 ), energy of the neutrino and antineutrino, and effect of excess neutrons over protons in the nuclear target.
