“…If the nucleon sea were flavour asymmetric, namelyū(x) d (x), one should have I G (Q 2 ) 1/3. Moreover, this result is supported by the existing neutrino-nucleon DIS data [3], and the most detailed analysis of muon-nucleon DIS data of NMC Collaboration [8]. It is worth noting that there are also some other works [20] of the light-quark flavour asymmetry deviation from the canonical value 1/3 for the Gottfired sum rule.…”

“…Up to now, there exists a number of sum rules for unpolarized and polarized structure functions, some of which are rigorous results and other which rely on more or less well justified assumptions [1]. The Adler sum rule [2] is exact and has no Quantum chromodynamics (QCD) perturbative corrections, but its experimental verification is at a very low level of accuracy [3]. This constant 2 of Adler sum rule is the result of the local commutation relations of the time components of the hadronic weak current [4], which is based on the fundamental quark structure of the standard model.…”

A new method to test the valence quark distribution of nucleon obtained from the maximum entropy method using Gottfried sum rule by performing DGLAP equations with the GLR-MQ-ZRS corrections and original LO / NLO DGLAP equations are outlined. The test relies on a knowledge of the unpolarized electron-proton structure function F ep 2 and electron-neutron structure function F en 2 and the assumption that Bjorken scaling is satisfied. In this work, the original Gottfried summation value obtained by the integrals of the structure function at different Q 2 is in accordance with the theoretical value 1/3 under the premise of light-quark flavour symmetry of nucleon sea, whether it is the result from the dynamics evolution equations or the result from global QCD fits of PDFs. Finally, we present the summation value of the LO / NLO DGLAP global fits of PDFs under the premise of light-quark flavour asymmetry of nucleon sea. According to analysis the original Gottfried summation value with two evolution equations at different Q 2 , we can know that the valence quark distributions of nucleon obtained by the maximum entropy method are effective and reliable.

“…The Gargamelle experiments discovered that the neutrino-nucleon cross-section rises linearly with energy. Finally, by combining their results, the BEBC and Gargamelle teams obtained the first evidence for scaling violation, namely the proof that the nucleon structure functions actually evolve with the resolution power of the observation [37]. …”

Experiments with high energy neutrino beams at CERN provided early quantitative tests of the Standard Model. This article describes results from studies of the nucleon quark structure and of the weak current, together with the precise measurement of the weak mixing angle. These results have established a new quality for tests of the electroweak model. In addition, the measurements of the nucleon structure functions in deep inelastic neutrino scattering allowed first quantitative tests of QCD.
