Azimuthal Asymmetries in DIS as a Probe of Intrinsic Charm Content of the Proton

L. N. Ananikyan, N. Ya. Ivanov

We calculate the azimuthal dependence of the heavy-quark-initiated $\mathcal{O}({\alpha }_s)$ contributions to the lepton-nucleon deep inelastic scattering (DIS). It is shown that, contrary…
