Experimental Studies of Diffractive Processes at HERA [PDF]

open access: yes, 2001
Diffractive processes in photon-proton interactions at HERA offer the opportunity to improve the understanding of the transition between the soft, non-perturbative regime in hadronic interactions at $Q^2 = 0$ and the perturbative region at high $Q^2 ...
