Spin and Parity Analysis of K anti-K pi System in the D and E/Iota Regions

Chung, S.U. ; Fernow, Richard C. ; Kirk, H. ; et al.
Phys.Rev.Lett. 55 (1985) 779, 1985.
Inspire Record 151125 DOI 10.17182/hepdata.20272

We have performed a high-statistics experiment on the reaction π−p→K+K¯0π−n at 8.0 GeV/c. A Dalitz-plot analysis of the K+K¯0π− system finds that the D(1285) is a JPG=1++ state coupling predominantly to a δπ decay channel, while the E(1420) peak consists mostly of a JPG=0−+ wave with a substantial δπ decay mode. There is little evidence of a 1++ resonance at the E mass.

Systematic Study of K pi Production in the Reaction K+- p --> K0(s) pi+- p: Technique and Measurements at 10-GeV/c

Baldi, R. ; Bohringer, T. ; Dorsaz, P.A. ; et al.
Nucl.Phys.B 134 (1978) 365-391, 1978.

A two-arm spectrometer for simple event topologies is described. Its main characteristics are: (i) large solid-angle acceptance for the forward emitted particles, owing to the absence of magnetic-momentum analysis; (ii) high-resolution time-of-flight measurement of the recoil proton, in the momentum-transfer range 0.05 < | t | < 1 (GeV/ c ) 2 ; (iii) high data-taking rate and on-line pattern recognition.

Spin-Parity Analysis of the Diffractively Produced Low Mass n pi System in the Reaction pi+- p --> pi+- (n pi)+ at 16-GeV/c

The Aachen-Berlin-Bonn-CERN collaboration Otter, G. ; Rudolph, G. ; Wieczorek, H. ; et al.
Nucl.Phys.B 130 (1977) 349, 1977.
Inspire Record 119192 DOI 10.17182/hepdata.35244

The dominant partial waves of the diffractively produced N π system at low Nπ masses (⩽ 1.4 GeV) are determined in the reactions π ± p → π (N π ) at 16 GeV/ c . A satisfactory description of our data can only be obtained by strong contributions of both a 1 2 − S-wave and a 3 2 + P-wave, violating the Gribov-Morrison rule. Spin and parity of the diffractively produced states are found from the interference between diffraction and Δ (1236) production. The interference term is obtained by an isospin analysis.

Analysis of the Reaction K- p --> K- pi- pi+ p at 40-GeV/c

The CERN-Serpukhov Boson Spectrometer Group collaboration Antipov, Yu.M. ; Ascoli, G. ; Busnello, R. ; et al.
Nucl.Phys.B 86 (1975) 381-402, 1975.
Inspire Record 90643 DOI 10.17182/hepdata.32087

The reaction K − p → K − π − π + p has been measured at 25 and 40 GeV/ c at the Serpukhov Proton Accelerator. The production cross section at 25 and 40 GeV/ c as a function of momentum transfer and K ππ mass is presented, and results of the partial-wave analysis of the K ππ system yielding information about Q(1300), K ∗ (1400) and L(1770) mesons are discussed.
