Energy Spectra of Light Species of Primary Cosmic Rays in the Energy Range from 100 GeV to 100 PeV
AbstractExperimental results obtained a few decades ago associate the knee with the bending of the light component ( p and He), and are compatible...

Modeling the TREK Detector’s Response When Detecting Muon Bundles from Ultra-High Energy Primary Cosmic Rays
AbstractThe TREK large-scale coordinate tracking detector is being created at MEPhI on the basis of drift chambers for detecting the near-horizontal...

Monte-carlo simulation of the effective lunar aperture for detection of ultra-high energy neutrinos with LOFAR
Ultra-high-energy (UHE) cosmic neutrinos interacting with the Moon’s regolith generate particle showers that emit Askaryan radiation. This radiation...

Cosmic Rays? Cosmic Particles
Cosmic rays are not rays. They are high energy particles arriving from outside the atmosphere, produced by the Sun and a number of different types of...

Propagation and fluxes of ultra-high energy cosmic rays in \(\varvec{f(R)}\) gravity theory
In this work, we study the effect of diffusion of ultra-high energy cosmic ray (UHECR) protons in the presence of turbulent magnetic fields (TMFs) in...

Testing Heavy Neutral Leptons in Cosmic Ray Beam Dump experiments
In this work, we discuss the possibility to test Heavy Neutral Leptons (HNLs) using “Cosmic Ray Beam Dump” experiments. In analogy with terrestrial...

Research on the knee region of cosmic ray by using a novel type of electron–neutron detector array
By accurately measuring composition and energy spectrum of cosmic ray, the origin problem of so called “knee” region (energy >one PeV) can be solved....

Study of Cosmic Ray Primary Mass Composition Using Monte Carlo Simulation and Statistical Methods
Tracing of cosmic ray origin and building a detailed and comprehensive idea about the sources are very much dependent on measurement of cosmic ray...

Nonlinear diffusive shock acceleration of cosmic rays: quasi-thermal and non-thermal particle distributions
Diffusive shock acceleration (DSA) of particles at collisionless shocks is the major accepted paradigm about the origin of cosmic rays (CRs). As a...

Interpretations of the cosmic ray secondary-to-primary ratios measured by DAMPE
Precise measurements of the boron-to-carbon and boron-to-oxygen ratios by DAMPE show clear hardenings around 100 GeV/n, which provide important...

Indirect Detection of Cosmic Rays
Cosmic rays entering the Earth’s atmosphere interact with the nuclei of air and produce cascades of secondary particles. At high energy (E ≳ 1014...
