Abstract: A sizable $\mathrm{cos}4\ensuremath{\phi}$ azimuthal asymmetry in exclusive dipion production near ${\ensuremath{\rho}}^{0}$ resonance peak in ultraperipheral heavy-ion collisions recently has been reported by STAR collaboration. We show that both elliptic gluon Wigner distribution and final-state soft… read more here.
