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

On the Possibility of Measuring the Single-tagged Exclusive Jets at the LHC
The feasibility studies of the measurement of the central exclusive jet
production at the LHC using the proton tagging technique are presented. In
order to reach the low jet-mass region, single tagged events were considered.
The studies were performed at the c.m. energy of 14 TeV and the ATLAS detector,
but are also applicable for the CMS-TOTEM experiments. Four data-taking
scenarios were considered: AFP and ALFA detectors as forward proton taggers and
= 0.55 m and = 90 m optics. After the event selection, the
signal-to-background ratio ranges between 5 and . Finally, the expected
precision of the central exclusive dijet cross-section measurement for data
collection period of 100 h is estimated
