Abstract:
We study the possibility to reconstruct
primary mass composition with the use of combinations of basic shower characteristics, measured
in hybrid experiments, such as depth of shower
maximum from fluorescence side and signal in water
Cherenkov tanks or in plastic scintillators from
the ground side. To optimize discrimination performance of shower observables combinations we apply
Fisher’s discriminant analysis and give statistical
estimates of separation of the obtained distributions
on Fisher variables for proton and iron primaries. At
the final stage we apply Multiparametric Topological
Analysis to these distributions to extract composition
from prepared mixtures with known fractions of
showers from different primary particles. It is shown,
that due to high sensitivity of water tanks to muons,
combination of signal in them with Xmax looks
especially promising for mass composition analysis,
provided the energy is determined from longitudinal
shower profile.
