Search for exotic events from the L3+C data

An effort to search for Kolar-like events within the data set of the L3+C experiment is reported. From a total of 0.89 × 1010 triggered events there are no reliable two-prong Kolar-like events observed. The corresponding event flux upper limit 7.1 × 10−13 cm−2 · s−1 · sr−1 at 90% confidence level is deduced based on some reasonable assumptions.
