Photon-induced processes allow many studies complementary to the
proton-proton physics program at the LHC. Potential of such studies is
greatly improved by the use of detectors placed close to the beamline, far
from the interaction point, to detect forward scattered protons. Using
proper simulation of the proton path along the beamline, the acceptance of
such forward detectors and the resolution of exchanged photon energy and
angle can be estimated. Results of such simulations will be presented,
including effects of the magnet misalignements. Finally, as an example of
interesting physics process to be studied in first phase of the LHC
running, the diffractive photoproduction of upsilon mesons will be
discussed.
This talk is a rehearsal for low-x workshop at Fermilab.
