Nuclear enhancement and suppression of diffractive structure functions at high energies

Understand

We compute diffractive structure functions for both protons and nuclei in the framework of Color Glass Condensate models with impact parameter dependence.

• These models have previously been shown to provide good agreement with inclusive F_2 measurements and exclusive vector meson measurements at HERA.
• For nuclei, they provide good (parameter free) agreement with the inclusive F_2 data.
• We demonstrate good agreement of our computations with HERA measurements on inclusive diffraction.
