The differential cross sections for they+ p-- n + 7T+ process were measured for y-quantum energies 200, 205 and 210 MeV and meson emission angles 16, 24, 36, 44, 56, 64, 76, 84, 96, 104, 116, 124, 136, 144 and 156° relative to the photon beam in the laboratory system. A phenomenological analysis of the results is carried out and some multipole charged-meson photoproduction amplitudes are determined. The results are compared with the predictions of the dispersion-relation theory.

Photoproduction of pi^0 eta on protons and the Delta(1700)D_{33} resonance

The Crystal Ball at MAMI & TAPS & A2 collaborations Kashevarov, V.L. ; Fix, A. ; Aguar-Bartolome, P. ; et al.

Inspire Record 811783 DOI 10.17182/hepdata.52974

Total and differential cross sections for the reaction gamma p -> pi^o eta p have been measured with the Crystal Ball/TAPS detector using the tagged photon facility at the MAMI C accelerator in Mainz. In the energy range E_gamma=0.95-1.4 GeV the reaction is dominated by the excitation and sequential decay of the Delta(1700)D33 resonance. Angular distributions measured with high statistics allow us to determine the ratio of hadronic decay widths \Gamma_{\eta \Delta}/\Gamma_{\pi S11} and the ratio of the helicity amplitudes A_{3/2}/A_{1/2} for this resonance.

Measurement of pi- p ---> pi0 n in the vicinity of the eta threshold

Starostin, A. ; Prakhov, S. ; Nefkens, B.M.K. ; et al.

We report a new measurement of the differential cross section for π−p→π0n from pπ=649 to 752 MeV/c, which is around the opening of the η channel (685 MeV/c). Our data support the main features of the π−p charge-exchange differential cross sections generated by the SAID πN partial-wave analysis. The opening of the η channel has a clear effect on the shape of the excitation function for dσ(π−p→π0n), which is most noticeable in the backward direction.

Measurement of pi- p ---> eta n from threshold to p (pi-) = 747-MeV/c

The differential cross section for η production in reaction π−p→ηn has been measured over the full angular range at seven incident π− beam momenta from threshold to pπ−=747 MeV/c using the Crystal Ball multiphoton spectrometer. The angular distributions are S wave dominated. At 10 MeV/c above threshold, a small D-wave contribution appears that interferes with the main S wave. The total η production cross section σtot is obtained by integration of dσ/dΩ. Starting at threshold, σtot rises rapidly, as expected for S-wave-dominated production. The features of the π−p→ηn cross section are strikingly similar to those of the SU(3) flavor-related process K−p→ηΛ. Comparison of the π−p→ηn reaction is made with η photoproduction.

K- p ---> pi0 pi0 Sigma0 at p(K)- = 514-MeV/c to 750-MeV/c and comparison with other pi0 pi0 production

Reaction K−p→π0π0Σ0 was measured with the Crystal Ball multiphoton spectrometer at eight K− momenta from 514 to 750MeV∕c. Dynamics and the energy dependence of the reaction are shown by Dalitz plots, invariant mass spectra, production angular distributions, and total cross sections. The dipion invariant-mass spectra for K−p→π0π0Σ0 show an enhancement in the low mass region; the opposite is the case for the K−p→π0π0Λ and π−p→π0π0n reactions. There is no direct evidence for a f0(600)-meson contribution to π0π0 production. Everywhere σt(K−p→π0π0Σ0)⪡σt(K−p→π0π0Λ).

Reaction K- p --> pi0 pi0 lambda from p(K-) = 514-MeV/c to 750-MeV/c.

Prakhov, S. ; Nefkens, B.M.K. ; Allgower, C.E. ; et al.

Inspire Record 650074 DOI 10.17182/hepdata.25228

Reaction K−p→π0π0Λ was measured at eight incident K− momenta between 514 and 750MeV∕c using the Crystal Ball multiphoton spectrometer. The reaction dynamics are displayed in total cross sections, Dalitz plots, invariant-mass spectra, production angular distributions, and the Λ polarization. The π0π0Λ production is dominated by the π0Σ0(1385) intermediate state; no trace of other light Σ∗ states is observed, and the role of the f0(600) meson appears to be insignificant. A striking similarity is seen between K−p→π0π0Λ and π−p→π0π0n; this can be understood as a consequence of dynamical flavor symmetry.
