Description

The ridge effect observed in high multiplicity events in proton-proton scattering at LHC can be due to the collisions of flux tubes in the projectiles which are in turn related to the fundamental physics of color confinement. We discuss observable effects due to gluon string collisions in electron-proton and peripheral proton-proton scattering related to scattering of photons. In the former case, the final-state ridges are expected to exhibit maximal multiplicity when the elliptic flow is aligned with the electron scattering plane. In the second example, the final-state multiplicity and elliptic flow are maximal when the proton scattering planes are aligned. Variation of these observables with azimuthal angle between projectile scattering planes is estimated to be on the order of several percent.
