Book excerpt: A counter and high-Z, optical spark chamber experiment was run at Brookhaven National Laboratory to measure the angular distributions of gamma ray final states of anti pp annihilation between 1.1 and 2.0 GeV/c incident anti p momentum. The general method of analysis used to determine the channel cross sections for the three reactions anti pp .-->. .pi./sup 0/.pi./sup 0/, .pi./sup 0/eta, and eta eta as well as the angular distributions for the first two. The results are presented for 1.862 GeV/c (.sqrt.s = 5.67) where the cross sections of all three reactions are approximately equal to 10.mu.b. The angular distributions of .pi./sup 0/.pi./sup 0/ and .pi./sup 0/eta show pronounced structure. The .pi./sup 0/.pi./sup 0/ data is combined with data of anti pp .-->. .pi./sup -/.pi./sup +/ to extract the pure I = 0 and I = 1 angular distributions. The possibility of cross channel effects is explored.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab experiment E835 has observed p¯p annihilation production of the charmonium state chic 0 and its subsequent decay into pi0pi0. Although the resonant amplitude is an order of magnitude smaller than that of the non-resonant continuum production of pi0pi 0, an enhanced interference signal is evident. A partial wave expansion is used to extract physics parameters. The amplitudes J = 0 and 2, of comparable strength, dominate the expansion. Both are accessed by L = 1 in the entrance p¯p channel. The product of the input and output branching fractions is determined to be B(p¯p → chic 0) x B(chic 0 → pi0pi0) = (5.09 +/- 0.81 +/- 0.25) x 10-7. An interference signal is also measured in the etaeta channels and provides B( p¯p → chic0) x B(chic0 → etaeta) = (4.0 +/- 1.2+0.5-0.3 ) x 10-7. The control channel pi 0eta, into which the chic0 decay is suppressed by isospin conservation, is analyzed and a 90% confidence level upper limit, B(chic 0 → p¯p) x B(chi c0 → pi0eta)
