Experimental limits on monojet production in e+e- annihilation at 29 GeV
A search was made for e+e--->X1X2 where X1 consists of one or more light unobservable particles and X2 decays promptly to a visible jet of particles. One event was found for an integrated luminosity of 176 pb-1, a rate consistent with known backgrounds. This result places a significant constraint on a number of theoretical models.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25641/3/0000191.pd
COMPARISON OF LIGHT QUARK AND CHARM QUARK FRAGMENTATION
Separate samples of charm quark and light quark (u, d, s) jets have been isolated in an experiment studying e+e- annihilations at s = 29 GeV. The results come from data corresponding to an integrated luminosity of 111 pb-1 collected by the High Resolution Spectrometer. Differences were observed in charged multiplicities, momentum distributions, and rapidity of the size expected from the different fragmentation functions and leading particle decay properties of the two samples. © 1985
