We generalized our model for the description of hard processes, and calculate the value of the azimuthal angular correlations (Fourier harmonics vn), for proton–proton scattering. The energy and multiplicity independence, as well as the value of vn, turns out to be in accord with the experimental data, or slightly larger. Therefore, before making extreme assumptions on proton–proton collisions, such as the production of a quark–gluon plasma in large multiplicity events, we need to understand how these affect the Bose–Einstein correlations, which have to be taken into account since the Bose–Einstein correlations are able to describe the angular correlations in proton–proton collisions, without including final state interactions.
