Abstract:
High precision muon chambers of the L3 detector permit the
measurement of the energy spectrum of muons over a large
momentum range, 50-2000 GeV/c, for single and multiple muons
with a very large solid angle area exposure factor. Interpretation
of these observations in terms of high energy cosmic ray astrophysics
would be greatly facilitated if energies of primary cosmic rays
which have generated the observed muons through their interaction
in the atmosphere could be measured with reasonable accuracy. We
present plans of the L3+Cosmics group to install a mini-air shower
array above the L3 detector to observe associated showers and
estimate the primary energy for about $\sim 20\%$ of the multiple
muon events observed with the L3 detector.
