“…The calculation of O(α s ) contributions require a much larger effort. In the calculations of the O(α S ) contributions, the phase space and loop integrations can be analytically reduced [9] to an integration over the two energy variables K and p 0 as shown in the final expressions for four-particle processes given by eqs. (B1) and (B2) and for three-particle processes given by eqs.…”

Deep inelastic scattering is considered in a statistical model of the nucleon. This incorporates certain features which are absent in the standard parton model such as quantum statistical correlations which play a role in the propagation of particles when considering Feynman diagrams containing internal lines.The inclusion of the O(α s ) corrections in our numerical calculations allows a good fit to the data for x ≥ 0.25. The fit corresponds to values of temperature and chemical potential of approximately T = 0.067 GeV and µ = 0.133 GeV. The latter values of parameters, however, give rise, for all x, to a large value for R = σ L /σ T .

Power corrections to the electromagnetic spectral function and the dilepton rate in QCD plasma within operator product expansion in D = 4

Abstract:We evaluate the electromagnetic spectral function in QCD plasma in a nonperturbative background of in-medium quark and gluon condensates by incorporating the leading order power corrections in a systematic framework within the ambit of the operator product expansion in D = 4 dimension. We explicitly show that the mixing of the composite operators removes mass singularities and renders Wilson coefficients finite and well defined. As a spectral property, we then obtain the nonperturbative dilepton production rate from QCD plasma. The operator product expansion automatically restricts the dilepton rate to the intermediate mass range, which is found to be enhanced due to the power corrections. We also compare our result with those from nonperturbative calculations, e.g., lattice QCD and effective QCD models based on Polyakov loop.
