Information Technologies on High-Energy Astrophysics: Cosmic Ray Anisotropy using HAWC Observatory

“…A primary cosmic ray (usually high energy proton or iron nucleus) produces an EAS with three components: 1The soft, or electromagnetic component, produces gamma rays through neutral pion decay, (2) the hard component (muons and hadrons), where charged and neutral kaons and pions decay into gamma rays, muons, neutrinos, antineutrinos, and nuclear fragments like protons and neutrons (e.g. [4][5][6][7]). For example, approximately 20% of 1 GeV muons produced at 10 km will reach sea level before decay, and (3) a nucleonic component, where highenergy nucleons, disintegration-product nucleons, and nuclear disintegration are present.…”
