How to measure the linear polarization of gluons in unpolarized proton using the heavy-quark pair leptoproduction
We study the azimuthal cosφ and cos2φ asymmetries in heavy-quark pair leptoproduction, lN→l′QQ¯X, as probes of linearly polarized gluons inside unpolarized proton, where the azimuth φ is the angle between the lepton scattering plane (l,l′) and the heavy quark production plane (N,Q). First, we dete...
