478. Initial results of a direct comparison between the Surface Detectors of the Pierre Auger Observatory and the Telescope ArrayR. Takeishi, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: The Pierre Auger Observatory (Auger) in Mendoza, Argentina and
the Telescope Array (TA) in Utah, USA aim at unraveling the
origin and nature of Ultra-High Energy Cosmic Rays (UHECR).
At present, there appear to be subtle differences between Auger
and TA results and interpretations. Joint working groups have
been established and have already reported preliminary
findings. From an experimental standpoint, the Surface
Detectors (SD) of both experiments make use of different
detection processes not equally sensitive to the components of
the extensive air showers making it to the ground. In particular, the muonic component of the shower measured at
ground level can be traced back to the primary composition,
which is critical for understanding the origin of UHECRs.
In order to make direct comparisons between the SD detection
techniques used by Auger and TA, a joint SD experimental
research program is being developed. In the first phase,
two Auger SD stations were deployed at the TA Central Laser
Facility to compare station-level responses. This paper
concentrates on the results obtained with the first Auger SD
station (an “Auger North” design), which has been operating
since October 2014. The second Auger SD station, identical to
the ones being operated at Auger in Argentina (an “Auger South”
design), was just deployed in June 2015. The second phase of
this research program will be to co-locate six Auger North SD
stations with TA stations in the field to compare event-level
responses.

479. Large-Scale Distribution of Arrival Directions of Cosmic Rays Detected at the Pierre Auger Observatory and the Telescope Array above 10[sup]19 eVOlivier Deligny, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: The large-scale distribution of arrival directions of
high-energy cosmic rays is a key observable in attempts to
understanding their origin. The dipole and quadrupole moments
are of special interest in revealing potential anisotropies.
An unambiguous measurement of these moments as well as
of the full set of spherical harmonic coefficients requires
full-sky coverage. This can be achieved by combining data from
observatories located in both the northern and southern
hemispheres. To this end, a joint analysis using data recorded
at the Pierre Auger Observatory and the Telescope Array above
10[sup]19 eV has been performed. Thanks to the full-sky
coverage, the measurement of the dipole moment reported in
this study does not rely on any assumption on the underlying
flux of cosmic rays. As well, the resolution on the quadrupole
and higher order moments is the best ever obtained. The
resulting multipolar expansion of the flux of cosmic rays
allows a series of anisotropy searches to be performed,
and in particular to report on the first angular power
spectrum of cosmic rays. This allows a comprehensive
description of the angular distribution of cosmic rays
above 10[sup]19 eV.

480. Report of the Working Group on the Composition of Ultra-High Energy Cosmic RaysMichael Unger, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: The atmospheric depth, Xmax, at which the particle number of
an air shower reaches its maximum is a good indicator for the
mass of the primary particle. We present a comparison of the
energy evolution of the mean of Xmax as measured by the
Telescope Array and c Collaborations. After
accounting for the different resolutions, acceptances and
analysis strategies of the two experiments, the two results are
found to be in good agreement within systematic uncertainties.
