A sensitivity of twist-4 and α s values extracted in the NLO QCD analysis of non-singlet SLAC-BCDMS-NMC deep inelastic scattering data to the choice of QCD renormalization scale (RS) is analyzed. It is obtained that the high twist (HT) contribution

We perform a detailed NLO analysis of the combined CCFR xF_3 and F_2 structure functions data and extract the value of alpha_s, parameters of distributions and higher-twist (HT) terms using a direct solution of the DGLAP equation. The value of alpha_

Analysis of possibilities of the γp collider in the TeV energy range, realized on the basis of UNK and VLEPP projects, is performed. It is shown that such a collider substantially increases the range of physics phenomena accessible for investigation

We extract the high-twist contribution to the neutrino-nucleon structure function $xF_3^{(\nu+\bar{\nu})N}$ from the analysis of the data collected by the IHEP-JINR Neutrino Detector in the runs with the focused neutrino beams at the IHEP 70 GeV prot
