Exclusive ${\eta }_c$ production from small-$x$ evolved Odderon at a electron-ion collider

Sanjin Benić, Davor Horvatić, Abhiram Kaushik +1

We compute exclusive ${\eta }_c$ 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…
