Partial Wave Analysis of K- p --> pi0 Lambda (1520) Between 1710-MeV and 2170-MeV Center-of-Mass Energy Including New Data Between 1775-MeV and 1960-MeV

We present extracted data for the pure I = 1 π 0 Λ (1520) channel from the reaction K − p → K − p π 0 at 11 incident momenta between 0.96 and 1.355 GeV/ c (1775 to 1960 MeV c.m. energy). A partial-wave analysis of this channel has been carried out over a broad c.m. energy range from 1710 to 2170 MeV using data at 27 momenta from this and earlier experiments. The 5 2 − Σ(1775) and built7 2 + Σ(2030) resonances are found to decay strongly to this channel. Amplitudes are also obtained for less dominant and less well-established resonances.

Partial Wave Analysis of $\bar{K} N \to \bar{K}^* N$ Between 1830-{MeV} and 2170-{MeV} Center-of-mass Energy Including New Data Below 1960-{MeV}

Inspire Record 131336 DOI 10.17182/hepdata.34833

We present data for the single-pion production final states K 0 π − p, K − π 0 p and K − π + n from K − p interactions at 11 c.m. energies between 1775 and 1957 MeV. Using the K 0 π − p events the branching ratio (K s 0 → π + π − /K s 0 → all) has been determined to be 0.657 ± 0.011. New values have also been determined for the masses and widths of the K ∗0 (890) and the K ∗− (8990). These give a value of 1.5 ± 1.5 MeV for the electromagnetic mass splitting of the K ∗ . Differential cross sections and the spin-density matrix elements have been extracted for the reactions K − p → K ∗− p and K − p → K ∗0 n . An energy dependent partial-wave analysis of the K ∗ N channel from threshold up to 2170 MeV c.m. energy has been carried out yielding values for 17 resonant amplitudes for the expected Y ∗ 's and a new resonance, the S01(2030).

TWO-BODY HYPERCHARGE EXCHANGE REACTIONS IN K- p AND pi+ p INTERACTIONS AT 10-GeV/c AND 16-GeV/c

The Aachen-Berlin-Bonn-CERN-Cracow-London-Vienna collaboration Girtler, P. ; Otter, G. ; Bottcher, H. ; et al.
Nucl.Phys.B 159 (1979) 397, 1979.
Inspire Record 146303 DOI 10.17182/hepdata.34626

Cross-section values or upper limits are presented for twenty-five two-body hypercharge-exchange reactions in K − p and π + p interactions at 10 and 16 GeV/ c . The 16 GeV/ c results are compared with some predictions of line-reversal plus exchange-degenerate Regge poles, of SU(3) and of the additive quark model. Agreement is found in all cases.

The Reactions $K^- p \to$ Pseudoscalar Meson $\Lambda(1520)$ at 4.2-{GeV}/$c$

The Amsterdam-CERN-Nijmegen-Oxford collaboration Barlag, S.J.M. ; Blokzijl, R. ; Jongejans, B. ; et al.
Nucl.Phys.B 149 (1979) 220-236, 1979.
Inspire Record 130106 DOI 10.17182/hepdata.34820

The total and differential cross sections of the reactions K − p → π 0 Λ (1520), ηΛ(1520) and η′ Λ(1520) have been measured. Prominent forward peaks are onserved in all three reactions. The first reaction shows also a backward peak. The spin density matrix elements of the Λ(1520) in this reaction are determined. For forward production the results show a remarkable alignment of the Λ(1520) corresponding to an M2 transition in the model of Stodolsky-Sakurai for 3 2 − baryon production.
