Abstract (english)
We compute exclusive 𝜂𝑐 production in high-energy electron-nucleon and electron-nucleus collisions that is sensitive to the odderon. In perturbative QCD the odderon is a 𝐶-odd color singlet consisting of at least three 𝑡-channel gluons exchanged with the target. By using the Color Glass Condensate effective theory our result describes the odderon exchange at the high-collision energies that would be reached at a future electron-ion collider. The odderon distribution is evolved to small-𝑥 using the Balitsky-Kovchegov evolution equation with running coupling corrections. We find that while at low momentum transfers 𝑡 the cross section off a proton is dominated by the Primakoff process, the odderon becomes relevant at larger momentum transfers of |𝑡|≥1.5  GeV2. We point that the odderon could also be extracted at low-𝑡 using neutron targets since the Primakoff component is strongly suppressed. In the case of nuclear targets, the odderon cross section becomes enhanced thanks to the mass number of the nuclear target. The gluon saturation effect induces a shift in the diffractive pattern with respect to the Primakoff process that could be used as a signal for the odderon.
