The location of ALICE detector allows the study the muonic component of cosmic-rays, since it is located 52 meters underground with 28 meters of rock above it. The ALICE detector is able to detect atmospheric muons from extensive air showers, making possible the study of cosmic-rays physics. At this depth, only atmospheric muons with energies greater than 16 GeV can reach the detection zone of ALICE. A study of cosmic charge ratio is presented for events of atmospheric showers collected in 2015, 2016, 2017 and 2018 by the ALICE experiment. The whole data sample corresponds to 62.5 days of data taking. The analysis of the multiplicity distribution of atmospheric muons reconstructed by the Time Projection Chamber (TPC) of ALICE is also presented. The rate of high muon multiplicity events (number of muons >100) was estimated and compared with the predictions given by QGSJET-II-04, SIBYLL and EPOS-LHC."pdfengCIENCIAS FÍSICO MATEMÁTICAS Y CIENCIAS DE LA TIERRAAstrofísica nuclearErupciones de rayos gammaGeomagnetismoEspectroscopía astronómicaRayos cósmicosTesis de doctoradoopenAccess
