| dc.description | We possess convincing experimental evidence for the fact that the real photon has non-trivial parton structure. On the other hand, interactions of the cosmic microwave background photons with high energy particles propagating through the Universe play an important role in astrophysics. In this context, to invoke the parton content could be convenient for calculations of the probabilities of different processes involving these photons. As an example, the cross section of inclusive resonant $W^+$ boson production in the reaction $νγ\to W^+X$ is calculated by using the parton language. Neutrino--photon deep inelastic scattering is considered. | |
| dc.description | 4 pages, 2 figures. The spin states of the initial particles in the reaction $νγ\to W^+X$ are correctly treated. As a result, the corresponding cross section becomes two times greater than the one from the previous version. Some changes in the text | |
