Abstract
Study of Ultra-High energy Cosmic Rays (UHECR) coming to Earth from the deep
cosmos has the potential to open the veil on some remaining mysteries in the field
of High Energy Physics and Astrophysics. Horizon-T detector system is constructed
to study the nature of UHECR by means of studying its interactions with the Earth
atmosphere that result in so-called Extensive Air Showers (EAS). The detector system
is based at Tien Shan High-altitude Science Station (TSHSS) of P.N. Lebedev Physical
Institute of the Russian Academy of Sciences. It is located near the Almaty city,
Kazakhstan, at ∼ 3400 meter above the sea level. About 2000 EAS were selected
from the Physics Run 1 that has been detected during the period from January
2017 to April 2017 at Horizon-T detector system. The simulation activities indicate
the existence of the "invariant" property of the standard EAS as defined by the
CORSIKA simulator. In this work, I analyzed single-peaked EAS events in order
to use this property as a new approach to EAS data analysis using the fine time
resolution feature of Horizon-T detector. The definition of this invariant property,
its test using data and the classification of the EAS events from Physics Run 1 are
described in this thesis.
