Study of rare processes induced by 209-Gev muons
Description
Analysis of dimuon final states from 1.4 x 1011 positive and 2.9 x 1010 negative 209-Gev muons in a magnetized iron calorimeter has set a lower limit of 9 Gev/c2 on the mass of a heavy neutral muon (M0), and a 90%-confidence level upper limit of sigma(μN→b anti bX)B(b anti b→μX)<2.9 x 10-36 cm2 for the production of bottom hadrons by muons. The dimuon mass spectrum from 102,678 trimuon final states places a 90%-confidence level upper limit for the muoproduction of upsilon states: sigma(μN→μ UPSILON X)B(UPSILON→μ+μ-)<22 x 10-39 cm2. In addition, analysis of 71 rare multimuon events, including 4- and 5-muon final states, is presented
