Title: Partial-wave analyses of $γ p \to η p$ and $γ n \to η n$ using a multichannel framework

Abstract

This paper introduces results from partial-wave analyses of the photoproduction reactions γp→ηp and γn→ηn. World data for the observables dσ/dΩ, Σ, T, P, F, and E were analyzed as part of this work. The dominant amplitude in the fitting range from threshold to a c.m. energy of 1900 MeV was found to be S₁₁ in both reactions, consistent with results of other groups. At c.m. energies above 1600 MeV, our solution deviates from published results, with this work finding higher-order partial waves becoming significant. Data off the proton imply that the higher-order terms contributing to the reaction include P₁₁, P₁₃, and F₁₅. The final results also hint that F₁₇ is needed to fit double-polarization observables above 1900 MeV. Data off the neutron show a contribution from P₁₃, as well as strong contributions from D₁₃ and D₁₅.

Partial-wave analysis of $γ p \to K^{+} Λ$ using a multichannel framework

Journal Article Hunt, B. C. ; Manley, D. M. - Physical Review C

Results from a partial-wave analysis of the reaction γp→K+Λ are introduced. The reaction is dominated by the S₁₁(1650) and P₁₃(1720) resonances at low energies and by P₁₃(1900) at higher energies. There are small contributions from all amplitudes up to and including G₁₇, with F₁₇ necessary for obtaining a good fit of several of the spin observables. We present evidence for P₁₁(1880), D₁₃(2120), and D₁₅(2080) resonances, as well as a possible F₁₇ resonance near 2300 MeV, which is expected from quark-model predictions. Some predictions for γn→K⁰Λ are also covered.

Updated determination of $N^{*}$ resonance parameters using a unitary, multichannel formalism

Journal Article Hunt, B. C. ; Manley, D. M. - Physical Review C

Results are presented for an updated multichannel energy-dependent partial-wave analysis of πN scattering. Our earlier research incorporated single-energy amplitudes for πN→πN, γN→πN, πN→ππN, πN→ηN, and πN→KΛ. The present work incorporates new single-energy solutions for γp→ηp up to a center-of-mass (c.m.) energy of 1990 MeV, γp→K+Λ up to a c.m. energy of 2230 MeV, and γn→ηn up to a c.m. energy of 1885 MeV, as well as updated single-energy solutions for πN→ηN, πN→KΛ, and γN→πN. Here, we introduce and discuss the resonance parameters obtained from a combined fit of all these single-energy amplitudes. Our determined energy-dependent amplitudes support an excellent descriptionmore »« less

Experimental study of the $γ p \to π^{0} η p$ reaction with the A2 setup at the Mainz Microtron

Here, the data available from the A2 Collaboration at MAMI were analyzed to select the γp → π⁰ηp reaction on an event-by-event basis, which allows for partial-wave analyses of three-body final states to obtain more reliable results, compared to fits to measured distributions. These data provide the world’s best statistical accuracy in the energy range from threshold to E_γ = 1.45 GeV, allowing a finer energy binning in the measurement of all observables needed for understanding the reaction dynamics. The results obtained for the measured observables are compared to existing models, and the impact from the new data is checkedmore »« less

Determination of ${}^{20}{Ne} (p, γ) {}^{21}{Na}$ cross sections from $E_{p} = 500 - 2000 keV$

Journal Article Lyons, S. ; Görres, J. ; deBoer, R. J. ; ... - Physical Review C

Background: The reaction ²⁰Ne(p,γ) ²¹Na influences the nucleosynthesis of Ne, Na, and Mg isotopes while contributing to hydrogen burning in several stellar sites, such as red giants, asymptotic giant branch (AGB) stars, massive stars, and oxygen-neon (ONe) novae. In the relevant temperature range for these environments (T = 0.05–0.5 GK), the main contributions to this reaction rate are from the direct capture process as well as the high-energy tail of a subthreshold resonance in the ground-state transition at E_x = 2425 keV in the ²¹Na compound nucleus. Purpose: The previous measurement of this reaction reports cross sections with large uncertaintiesmore »« less
