When they undergo a charged-current interaction, the short lifetime of the tau gives rise to regenerated neutrinos at relatively high energies. ANITA recently reported two EeV showers which, at first glance, could be interpreted as emerging tau neutrinos. Their emergence angle was shown to be in tension with the expected angular distribution from isotropic astrophysical neutrinos. However, localized emission from a point source in the event's direction can evade diffuse bounds. In this work, we present an updated and precise calculation of the tau-regeneration effect using a newly developed Monte Carlo package, TauRunner. We describe the algorithm and the software’s capabilities, and apply it to the anomalous ANITA detections. We show that any flux from the direction of the ANITA events should be accompanied by secondary tau-neutrinos detectable at IceCube. We derive the maximum allowed secondary flux at IceCube and use it to infer the maximum number of events ANITA would detect. We find that ANITA should see not more than $10^{-6}$ events, requiring a significant over-fluctuation to account for the anomalous event in 2014.","PeriodicalId":166008,"journal":{"name":"Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123278995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas the ground pressure is quite easy to measure (a first order linear correction can be readily perform), the correction of the temperature effect on muon detectors is particularly complicated; as a matter of fact no standard method exists. \u0000 \u0000Trasgo detectors are high resolution tracking devices, providing: (i) high resolution on position and time, (ii) the capability of measuring high-multiplicity events, and (iii) some muon-electron separation. As different event topologies do correspond -usually- to different evolution of showers, then by keeping memory of the different pressure layers of the atmosphere, the analysis of the trends of different multiplicity and composition events may provide information in real time of the changes of the temperature in high levels of the atmosphere. \u0000This feature opens the door to the development of auto-calibrated detectors, able to perform a real time estimation of the temperature profile of the atmosphere, as well as a real time correction of the data by the atmospheric effect. \u0000 \u0000Some preliminary results on the correlations between cosmic rays and temperature profile of the atmosphere (using data taken with the TRAGALDABAS detector at the Univ. of Santiago de Compostela) will be shown and discussed.","PeriodicalId":166008,"journal":{"name":"Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126226770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
