The lateral trigger probability function for the ultra-high energy cosmic ray showers detected by the Pierre Auger Observatory
(Elsevier BVAmsterdam, 2011-12)
In this paper we introduce the concept of Lateral Trigger Probability (LTP) function, i.e., the probability for an Extensive Air Shower (EAS) to trigger an individual detector of a ground based array as a function of ...
Performance of CMS muon reconstruction in pp collision events at √s = 7TeV
The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 pb-1 of data collected in pp collisions at s = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria ...
The fluorescence detector of the Pierre Auger Observatory
The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays. It combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development ...
Techniques for measuring aerosol attenuation using the Central Laser Facility at the Pierre Auger Observatory
(Institute of Physics - IOPBristol, 2013-04)
The Pierre Auger Observatory in Malargüe, Argentina, is designed to study the properties of ultra-high energy cosmic rays with energies above 1018 eV. It is a hybrid facility that employs a Fluorescence Detector to perform ...
A composition dependent energy scale and the determination of the cosmic ray primary mass in the ankle region
At present there are still several open questions about the origin of the ultra high energy cosmic rays. However, great progress in this area has been made in recent years due to the data collected by the present generation ...
Improving photon-hadron discrimination based on cosmic ray surface detector data
(Elsevier Science, 2013-06)
The search for photons at EeV energies and beyond has considerable astrophysical interest and will remain one of the key challenges for ultra-high energy cosmic ray (UHECR) observatories in the near future. Several upper ...
