Study of the reaction p̄p ̃ff from 1.1 to 2.0 GeV/c

چکیده
A study has been performed of the reaction p̄p→4K using in-flight antiprotons from 1.1 to 2.0 GeV/c incident momentum interacting with a hydrogen jet target. The reaction is dominated by the production of a pair of f mesons. The p̄p→ff cross section rises sharply above threshold and then falls continuously as a function of increasing antiproton momentum. The overall magnitude of the cross section exceeds expectations from a simple application of the Okubo-Zweig-Iizuka rule by two orders of magnitude. In a fine scan around the j/ f J(2230) resonance, no structure is observed. A limit is set for the double branching ratio B(j→ p̄p) 3B(j→ff),6310 for a spin 2 resonance of M52.235 GeV and G515 MeV. @S0556-2821~98!02511-9#

متن کاملHELICITY AND PLANAR AMPLITUDES IN PION-PROTON SCATTERING AT 6.0 GeV/c
In addition to optimal conditions, invariant laws of Lorentz, parity and time reversal are imposed to find the relation between observables (spin rotation parameters) and bilinear combination of helicity amplitudes in pion-proton elastic scattering at 6.0 GeV/c. By normalizing the differential cross-section to unity, the magnitudes of helicity amplitudes and the angle between them are dete...

Average values of< 1- T >where T is the thrust are presented for e: e: AMY data and are compared with their values in hadronic interactions. As far as possible, similar analysis techniques have been employed in the two different interactions. Similar variation with E is observed for this average in both data. The values of < PT> and < PL > relative to the thrust axis in e e are simila...
