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.

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.

Partial Wave Analysis of the Q Region in the Reactions K- p --> K- pi+ pi- p and K- p --> anti-K0 pi- pi0 p at 14.3-GeV/c

Tovey, S.N. ; Hansen, J.D. ; Paler, K. ; et al.

Nucl.Phys.B 95 (1975) 109-129, 1975.

Inspire Record 2363 DOI 10.17182/hepdata.31975

We have studied the reactions K − p → K − π + π − p and K − p → K 0 π − π 0 p at 14.3 GeV/ c using respectively 15 992 and 3723 events. Partial-wave analysis of the region 1.0 < m (K ππ ) < 1.7 GeV have been made using a modified version of the method developed at the University of Illinois.

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.
