Muon-Pair Separation Measurements and Comparison with Transverse-Momentum Models

Rates of high-energy cosmic-ray muon pairs have been measured for separations up to 70 m. Detailed calculations imply that the mean transverse momentum of mesons with x>0.01 is 0.66plus-or-minus0.10 GeV/c at laboratory energies of approximately-greater-than10 000 GeV. We find that the high-pT muo...

Beschreibung
Zusammenfassung:	Rates of high-energy cosmic-ray muon pairs have been measured for separations up to 70 m. Detailed calculations imply that the mean transverse momentum of mesons with x>0.01 is 0.66plus-or-minus0.10 GeV/c at laboratory energies of approximately-greater-than10 000 GeV. We find that the high-pT muons result mostly from decay of abundantly produced particles with lifetimes approximately-greater-than10-8sec, such as pions and kaons.
