Search forϕ-Meson Production in 3.7-GeV/cπ−−pCollisions

“…4) show a significant bump at M*(0) = 1700 MeV which is probably due to the 1688-MeV, T = 1/2 resonance previously observed in Ti-p total cross-section measurements. 5 It appears that in about 25% of our w productions, the outgoing Tf'-p form this N* state. The events with M*(7r"/>) inside 1700± 80 MeV show a large anisotropy in a^Y [ Fi S» 3(b)], whereas the "outside" events show no significant anisotropy.…”

“…84, 5 and (cp -~K + K~)/(<p-K*K~ +K 1°K2°) = 0. 57, 6 and make the assumption that all of the cp decay is into the KK channel, 7 then we obtain an upper limit for the ratio of the production cross sections ^C^LM< ( o.…”

Concrete Quarks - The Beginning of the End

“…Although aces resolved the problem of φ decay, explained many regularities, and made predictions that could easily be tested, some predictions contradicted experiment, and even violated basic theoretical principles. Matt Roos's "definitive" compilation of resonances, published in the 1963 Reviews of Modern Physics, lists 26 meson resonances [14]. We now know that 19 of these resonances do not exist, and of those 19,7 are exotic, i.e., cannot be made from deuces.…”

Blind Analysis in Nuclear and Particle Physics

“…We have looked instead at the individual measurements, compiled by the PDG or by other reviews, and compared them to the published values which existed at the time of the measurement. decay [9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,7,8]. The measurements are shown as open dots, with the error bars depicting the uncertainties published along with the measurement.…”
