Anomalously behavior of CR barometric effect deep underground: possible influence of EAS muons
2019 August 03
According to the Baksan underground scintillation telescope’s data the barometric coefficients for six intervals of zenith angles of particle registration were obtained for ten years (2003-2012). The obtained barometric coefficients exceed an order of magnitude the theoretical values – the obtained value for the vertical β = (0.051 ± 0.010) %/mb. Nevertheless, these results are in good agreement with the data obtained for the barometric effect of high-energy muons in a number of papers of other authors. And there is a noticeable increase of the absolute values of the measured barometric coefficients with increasing of the threshold energy of muons.
