Investigation of Muon Puzzle with GRAPES-3 Experiment

Abstract

One of the outstanding problems in cosmic ray (CR) physics is the mismatch between simulated and observed muon numbers termed as the muon puzzle.While a theoretical investigation is needed, it is necessary to obtain as much as data possible beyond any ambiguity from various experiments, sensitive in different energy ranges of cosmic ray spectrum.The GRAPES-3 experiment located at Ooty, India is sensitive to the observation of cosmic rays over a wide range of energies from 1013 to 1016 eV.The large area muon detector of GRAPES-3 provides a sensitive measurement of muon content in the cosmic ray showers.An investigation of muon puzzle based on the Monte Carlo simulation of cosmic ray showers with CORSIKA is discussed. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
