INCLUSIVE PRODUCTION OF NONSTRANGE MESON RESONANCES IN P N INTERACTIONS AT 19-GEV/C

The SCANDINAVIAN BUBBLE CHAMBER collaboration Bakken, V. ; Breivik, F.O. ; Jacobsen, T. ;
Nuovo Cim.A 70 (1982) 105-131, 1982.
Inspire Record 182838 DOI 10.17182/hepdata.37528

Data on inclusive and semi-inclusive production of nonstrange meson resonances from a bubble chamber study of pn interactions at 19 GeV/c are presented. Most of the results concern ρ0 production. The inclusive cross-sectionσ(pn → ρ0+x)=(2.4±0.4) mb agrees well with pp data. The ρ0 cross-sections are equal in the protonlike and neutron-like hemispheres. The differential cross-sections are in general agreement with earlier observation in pp interactions. In the fragmentation region the approximate structure function can be described byEdσ/dx= =a(1−|x|)n withn=3.0±0.8 in agreement with recent predictions from quark counting rules. The production of ω(780) is observed in the reaction pn→pp+ω+X with a cross-section σ=(0.13±0.03) mb. There is indication of f0(1270) and g(1680) production.

Evidence for a New $K^* \bar{K}$ State at a Mass of 1530-{MeV} With Ij (Pc) = 1++ Observed in $K^- p$ Interactions at 4.2-{GeV}/$c$

Gavillet, P. ; Armenteros, R. ; Aguilar-Benitez, M. ; et al.
Z.Phys.C 16 (1982) 119, 1982.
Inspire Record 180923 DOI 10.17182/hepdata.16388

Evidence is presented for a newK*\(\bar K\)+c.c. resonance with a mass of (1,526±6) MeV, a width of (107±15) MeV and quantum numbersIJPC=01++. We call itD′ meson. Initially it is observed as aK*\(\bar K\)+c.c. enhancement in the reactionsK−p→(Ks0K±π∓)Λ at 4.2 GeV/c. The isospin assignmentI=0 comes from its further observation in the reactionsK−p→(Ks0K±π∓)Σ0 andK−p→(Ks0K±π∓)Σ(1,385)0 but not inK−p→(K+K−π−)Σ+ orK−p→(Ks0K±π∓)Σ(1,385)+. A maximum likelihood analysis of the (K\(\bar K\)π) decay Dalitz plots in the reactionsK−p→(Ks0K±π∓) determines theJPC of theD′ meson to be 1++. A satisfactorySU(3) fit is obtained to a 1++ nonet composed of theI-1A1, theI=1/2QA with theD(1,285) and theD′(1,526) as theI=0 members having a mixing angle close to the magic one.

A PARTIAL WAVE ANALYSIS OF THE (K pi pi) SYSTEM IN THE REACTION pi- p ---> (K+ pi- pi0) LAMBDA AT 3.95-GeV/c

The CERN-College de France-Madrid-Stockholm collaboration Fernandez, C. ; Aguilar-Benitez, M. ; Cerrada, M. ; et al.
Z.Phys.C 16 (1982) 95, 1982.
Inspire Record 178875 DOI 10.17182/hepdata.16389

Results from a partial wave analysis of theKππ system produced in the hypercharge exchange reaction π−p→(K+π−π0)Λ at 3.95 GeV/c are presented. SignificantQ1 production is observed but no evidence is found forQ2 production thus confirming the results obtained in a previous decay Dalitz plot analysis of the same reaction. The relative phase behaviour of the 1+(Kϱ) partial waves obtained with the present analysis provides additional confirmation of the resonance interpretation of theQ1 enhancement. Information is also obtained about its production properties and the role played by the Λ polarization in the hypercharge exchange reaction. This is compared with the results obtained in the reactionK−p→(π+π−π0)Λ at 4 GeV/c.
