A measurement of the decay KL→π0γγ

Physics Letters B 284:3-4 (1992) 440-447

Abstract:

The full data set of the experiment NA31 at CERN has been used to analyse the decay mode KL→π0γγ. A signal of 63 events has been observed with an estimated background of 6.0±1.7 events, corresponding to a branching ratio of (1.7±0.3)×10-6 consistent with our previous result based on partial statistics. The invariant mass spectrum of the two photons is found to be consistent with chiral perturbation theory, and the decay is dominated by the J = 0 two photon state. © 1992.

Search for magnetic monopoles with the Soudan 2 detector

Abstract:

A search for grand unified theory magnetic monopoles making highly ionizing tracks in argon gas has been conducted using the Soudan 2 nucleon decay detector. This underground detector is a large fine-grained tracking calorimeter comprised of long drift tubes read out by proportional wires. No monopole candidates were observed in data taken over almost three years, yielding an upper flux limit of 8.7 × 10-15 cm-2s-1sr-1 for monopole velocities of >2×10-3. © 1992 The American Physical Society.
