Description
Summary:The Large Volume Detector (LVD), in the INFN Gran Sasso National Laboratory (Italy), has been taking data since June 1992. The experiment, 1 kton of liquid scintillator at the equivalent depth of 3600 m w.e., has been mainly designed to observe low energy neutrinos from the core collapse of a supernova but allows also the measure of the atmospheric muon flux underground as well as the induced neutron production. In this work we summarize the results of the analysis of the global LVD data set, 5.6 107 muons in a livetime of 8402 days collected during 24 years of continuos operations since 1994 up to 2017. The present measurement represents an unprecedented collection obtained by a unique experiment in a fixed location. The modulation in time of the flux and its correlation with the the effective temperature in the upper atmosphere are here discussed.
