Accessing the distribution of linearly polarized gluons in unpolarized hadrons
Gluons inside unpolarized hadrons can be linearly polarized provided they
have a nonzero transverse momentum. The simplest and theoretically safest way
to probe this distribution of linearly polarized gluons is through cos(2 phi)
asymmetries in heavy quark pair or dijet production in electron-hadron
collisions. Future Electron-Ion Collider (EIC) or Large Hadron electron
Collider (LHeC) experiments are ideally suited for this purpose. Here we
estimate the maximum asymmetries for EIC kinematics.Comment: 4 pages, 2 figures, to appear in the proceedings of the XIX

Probing the linear polarization of gluons in unpolarized hadrons at EIC
Gluons inside unpolarized hadrons can be linearly polarized provided they have a nonzero transverse momentum. The simplest and theoretically safest way to probe this TMD distribution of linearly polarized gluons is through cos 2{phi} asymmetries in heavy quark pair or dijet production in electron-hadron collisions. Future EIC or LHeC experiments are ideally suited for this purpose. Here we estimate the maximum asymmetries for EIC kinematics
