“…(91) and also used a parametrization with an additional x k term, with free parameter k. In spite of the new parameters, all acceptable results (i.e. with the values of χ 2 comparable to our best fit solution) extracted from fits to data were very similar to the ones obtained with parametrization (91). We emphasize that the behaviour of the function δf 2 (x) for x < 0.70 is well constrained by data and only small variations on both the shape and the position of the zero x 0 are allowed.…”

We present the results of a phenomenological study of unpolarized nuclear structure functions for a wide kinematical region of x and Q 2 . As a basis of our phenomenology we develop a model which takes into account a number of different nuclear effects including nuclear shadowing, Fermi motion and binding, nuclear pion excess and off-shell correction to bound nucleon structure functions. Within this approach we perform a statistical analysis of available data on the ratio of the nuclear structure functions F 2 for different nuclei in the range from the deuteron to the lead. We express the off-shell effect and the effective scattering amplitude describing nuclear shadowing in terms of few parameters which are common to all nuclei and have a clear physical interpretation. The parameters are then extracted from statistical analysis of data. As a result, we obtain an excellent overall agreement between our calculations and data in the entire kinematical region of x and Q 2 . We discuss a number of applications of our model which include the calculation of the deuteron structure functions, nuclear valence and sea quark distributions and nuclear structure functions for neutrino charged-current scattering. * kulagin@ms2.inr.ac.ru † Roberto.Petti@cern.ch

Abstract.A statistical quark model, with quark energy levels given by a central linear confining potential is used to obtain the light sea-quark asymmetry, d/u, and also for the ratio d/u, inside the nucleon. After adjusting a temperature parameter by the Gottfried sum rule violation, and chemical potentials by the valence up and down quark normalizations, the results are compared with experimental data available.Keywords: flavor symmetries, structure function, quark models PACS: 11.30.Hv, 12.39.x, 14.65.Bt We report results for the light sea-quark asymmetry, In Fig. 1, we report the results we have obtained by the model for the ratios d/u [in the left frame of Fig. 1] and d/u [right frame of Fig.1], as functions of the Bjorken scale x. Initially, in spite of the fact that we fit the GSR violation with such a model, we obtain a constant ratio between the proton and neutron structure functions [constant dashed line of Fig.1]. Next, we incorporate in the model contributions from gluonic splitting processes, which is represented by the parameter a s . This is shown in the left frame of Fig.1 [6]. Using this prescription, the constituent structure of the quark (antiquark) in

“…Many ν-DIS experimental programmes, such as BEBC [29], CDHS [30], E545 [31], and, etc.,were carried out in order to have proper information about structure of nucleon, nuclear effect(EMC), mixing angle of weak interaction, etc. But none of them were able to confirm the EMC effect due to the presence of statistical uncertainties with the measurements.…”

We present an analysis of the xF3(x, Q 2 ) structure function and Gross-Llewellyn Smith(GLS) sum rule taking into account the nuclear effects and higher twist correction. This analysis is based on the results presented in "N. M. Nath et al., Indian J Phys 90(1), 117 (2016)". The corrections due to nuclear effects predicted in several earlier analysis are incorporated to our results of xF3(x, Q 2 ) structure function and GLS sum rule for free nucleon, corrected upto next-next-to-leading order (NNLO) perturbative order and calculate the nuclear structure function as well as sum rule for nuclei. In addition, by means of a simple model we have extracted the higher twist contributions to the non-singlet structure function xF3(x, Q 2 ) and GLS sum rule in NNLO perturbative orders and then incorporated them to our results. Our NNLO results along with nuclear effect and higher twist corrections are observed to be compatible with corresponding experimental data and other phenomenological analysis.
