Inspire Record 111700 DOI 10.17182/hepdata.37594

New data on the K−p elastic and charge exchange reactions are presented in the K− momentum range between 1.934 GeV/c and 2.516 GeV/c. A conventional energy-dependent partial-wave analysis covering the widerPK- range from 1.6 GeV/c to 2.516 GeV/c is presented together with a p.w.a. in which the duality ands-helicity conservation ideas are explicitly imposed in the fits. Finally the new Y*’s observed in this experiment are classified inSU3 multiplets.

rivet Analysis
The Total Hadronic Cross-Section for e+ e- Annihilation Between 3.1-GeV and 4.8-GeV Center-Of-Mass Energy

The PLUTO collaboration Burmester, J. ; Criegee, L. ; Dehne, H.C. ; et al.
Phys.Lett.B 66 (1977) 395-400, 1977.
Inspire Record 110272 DOI 10.17182/hepdata.27583

Using the solenoidal magnetic detector PLUTO, we have measured the total cross section for e + e − annihilation into hadrons. Results are presented for center of mass energies between 3.6 and 4.8 GeV, and in the regions of the J ψ (3.1) and ψ(3.7) resonances. We also present results for the 2 prong cross section in the energy range 3.6 to 4.8 GeV.

New Data on K- p --> omega Lambda from 1.934-GeV/c to 2.516-GeV/c and Partial Wave Analyses from Threshold Up to 2436-MeV CMS Energy

Baccari, B. ; Poulard, G. ; Revel, D. ; et al.
Nuovo Cim.A 41 (1977) 96, 1977.
Inspire Record 110575 DOI 10.17182/hepdata.37595

We present the results of a bubble chamber study of the pure-isospinI = 0 reaction K−p → ωΛ at 7 incident momenta between 1.934 and 2.516 GeV/c. An energy-dependent partial-wave analysis in the c.m. energy range (2070 ÷ 2436) MeV including these new data confirms the coupling of theG7 Λ(2100) to this channel and yields evidence for the existence of a new resonant stateD3or P3 Λ(2325). A semi-energy-independent partial-wave analysis is also carried out, by means of all available data from the threshold of the K−p → ωΛ reaction up to 2436 MeV. This supplies clear and unambiguous evidence for the contribution of the knownP3 Λ(1860) and of the above-proposedD3 Λ(2325) to the ωΛ channel.

Anti-Proton-Proton Annihilation Into pi+ pi- and K+ K- at 6.2-GeV/c

Buran, T. ; Eide, A. ; Helgaker, P. ; et al.
Nucl.Phys.B 116 (1976) 51-64, 1976.
Inspire Record 110027 DOI 10.17182/hepdata.35565

The angular distributions for the two annihilation channels p ̄ p →π + π − and p ̄ p → K + K − have been measured at 6.2 GeV/ c . The two-pion channel shows peripheral peaks for π + and π − going forward, and the two-kaon channel shows a peripheral peak for the K − going forward. The results have been compared with the line-reversed elastic backward scattering reactions and also with a constituent interchange model.

Phys.Rev.Lett. 37 (1976) 83-84, 1976.
Inspire Record 945158 DOI 10.17182/hepdata.21039

Polarization in π−p elastic scattering, with emphasis in the region around the secondary dip and also θc.m.=90°, has been measured at 2.93 and 3.25 GeV/c. We observe an interesting sign change in this angular region.

Resonance Production in the Reaction K+ p --> K0 p pi+ at 5-GeV/c, 8.25-GeV/c and 16-GeV/c

Inspire Record 108770 DOI 10.17182/hepdata.35742

We present a systematic analysis of the production of K ∗+ (892) and Δ ++ (1236) resonances in the K + p → K 0 p π + reaction at 5, 8.25 and 16 GeV/ c . We have measured total cross sections, differential cross sections, density matrix elements and examined resonance production mechanisms in terms of the exchange of states with definite naturality. Some results on the reaction K + p → K ∗+ (1420) p are also given.

Evidence for Structure in the 1+ State of the Q Region

The Aachen-Berlin-CERN-London-Vienna & Ecole Poly-Rutherford-Saclay collaborations Otter, G. ; Rudolph, G. ; Schmid, P. ; et al.
Nucl.Phys.B 106 (1976) 77-94, 1976.
Inspire Record 3373 DOI 10.17182/hepdata.35803

We have performed a partial-wave analysis of the mainly diffractively produced low-mass (K ππ ) system in the reactions K − p → K − π + π − p and K − p → K 0 π − π 0 p at 10, 14 and 16 GeV /c . We find that the dominant 1 + S ( K ∗ π ) state has possibly a two-peak structure (around 1.27 and 1.37 GeV). In contrast the 1 + S(K ϱ ) state shows one narrow peak near thershold (around 1.27 GeV). These states are found to be of different origin. The results favour the interpretation of the 1 + S(K ϱ ) as a 1 + resonance below the (K ϱ ) threshold. The t ′ pp dependence is found to be different for the 1 + and 0 − states.
