Diffractive Bremsstrahlung at High- LHC Case Study
Feasibility studies of the measurement of the exclusive diffractive
bremsstrahlung cross-section in proton-proton scattering at the centre of mass
energy of 13 TeV at the LHC are reported. Present studies were performed for
the low luminosity LHC running with the betatron function value of 90~m using
the ATLAS associated forward detectors ALFA and ZDC. A simplified approach to
the event simulation and reconstruction is used. The background influence is
also discussed.Comment: 20 pages, 10 figures. arXiv admin note: substantial text overlap with

Feasibility Studies of the Diffractive Bremsstrahlung Measurement at the LHC
Feasibility studies of an observation of the exclusive diffractive
bremsstrahlung in proton-proton scattering at the LHC are reported. A
simplified approach to the photon and the scattered proton energy
reconstruction is used. The background influence is discussed.Comment: 15 pages, 6 figure
Alignment-related Effects in Forward Proton Experiments at the LHC
The activity in the field of diffractive physics at the Large Hadron Collider
has been constantly increasing. This includes the planning for additional
dedicated apparatus -- horizontal forward proton detectors. This work focuses
on the problems related to the alignment of such devices. The effects of the
misalignment of the detectors on their geometric acceptance and on the
reconstruction of the proton kinematics are studied. The requirements for the
alignment precision are inferred for different types of possible measurements.Comment: 15 pages, 29 figure
Technical Design Report for the ATLAS Forward Proton Detector
The ATLAS Forward Proton (AFP) detector provides measurements of the momentum and emission angle of very forward protons. This enables the observation and measurement of a range of processes where one or both protons remain intact. Such processes are associated with elastic and diffractive scattering
