Decay angular distributions in diffractive one-pion production at ISR energy
New experimental results are reported on decay angular distributions in diffractive dissociation of protons into (n pi /sup +/) in proton- proton collisions at a centre-of-mass energy of square root s=45 GeV. There is strong evidence for two distinct components of diffraction dissociation which have...

| description | New experimental results are reported on decay angular distributions in diffractive dissociation of protons into (n pi /sup +/) in proton- proton collisions at a centre-of-mass energy of square root s=45 GeV. There is strong evidence for two distinct components of diffraction dissociation which have different decay angular distributions in the Gottfried-Jackson frame; the resonant and the non-resonant component with (n pi /sup +/) invariant mass in the interval 1.6<m<1.7 GeV are separated by their different t dependence. Strong violation of s- channel and t-channel helicity conservation for both the resonant and the non-resonant component is found. (10 refs). |
