Barometric Effect of High-Energy Muons (>230 GeV)

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 papers of other authors. And there is a noticeable increase of the absolute values of the measured barometric coefficients with increase of the threshold energy of muons.
