“…The INFN-MAMBO Collaboration studies hadron photoproduction with and without polarization at different accelerators: ELSA (ELectron Stretcher Accelerator), delivering (un)polarized electrons in the 0.5-3.5 GeV energy range, in Bonn and MAMI (the Mainz Microtron). The BGOOD experiment, working at ELSA, is designed to investigate the hadron structure, studying exclusive channels of meson photoproduction on the nucleon [37][38][39]. It consists of two main parts: (1) a central detector with a Bismuth Germanium Oxide (BGO) crystal calorimeter, a plastic scintillator barrel and two Multi Wire Proportional Chambers (MWPCs); (2) a forward large aperture magnetic spectrometer.…”

Particle identification techniques are fundamental tools in nuclear physics experiments. Discriminating particles or nuclei produced in nuclear interactions allows to better understand the underlying physics mechanisms. The energy interval of these reactions is very broad, from sub-eV up to TeV. For this reason, many different identification approaches have been developed, often combining two or more observables. This paper reviews several of these techniques with emphasis on the expertise gained within the current nuclear physics scientific program of the Italian Istituto Nazionale di Fisica Nucleare (INFN).

“…However, different resonance contributions have been suggested based on the included data set in the PWA due to the existing discrepancies between the CLAS [319] and the SAPHIR [318] data sets [326]. Here, the latest high-precision data from BGOOD [327] was able to resolve this issue for the very forward angles cos θ K CM > 0.9, where they report a good agreement to the CLAS data. In addition, this data helps to constrain the t-channel K and K * exchange at forward angles and low momentum transfer.…”

This review treats the advances in Light Baryon Spectroscopy of the last two decades, which were mainly obtained by measuring meson-production reactions at photon facilities all over the world. We provide a consistent compendium of experimental results, as well as a review of the theoretical methods of amplitude analysis used to analyze the data. The most significant datasets are presented in detail and are listed in combination with a full set of the relevant references. In addition, a brief summary of spin-formalisms, which are ubiquitous in Light Baryon Spectroscopy, as well as a review on complete experiments, are provided. The synthesis of the reviewed knowledge is presented in a full interpretation of the new results on the Light Baryon Spectrum.

“…To avoid inconsistencies, we fit instead the very recent measurement from the BGOOD experiment at ELSA [82]. The BGOOD data on dσ/d and P at forward angles for K + photoproduction [83] are also included. Compared to the JüBo2017 analysis [58], a number of recent data sets were additionally included in the fit, such as new data in ηp photoproduction for the beam asymmetry [84] and T , E, P, H , and G [46] by the CBELSA/TAPS Collaboration.…”

Light baryon resonances from a coupled-channel study including $$\mathbf {K\Sigma }$$ photoproduction

The Jülich-Bonn dynamical coupled-channel approach is extended to include $$K\Sigma $$ K Σ photoproduction off the proton. Differential cross section and (double) polarization data for $$K^+\Sigma ^0$$ K + Σ 0 and $$K^0\Sigma ^+$$ K 0 Σ + are analysed simultaneously with the pion- and photon-induced production of $$\pi N$$ π N , $$\eta N$$ η N , $$K\Lambda $$ K Λ , and $$K\Sigma $$ K Σ final states, totaling almost 72,000 data points for center-of-mass energies $$W<2.4$$ W < 2.4 GeV. Based on the fit results the spectrum of $$N^*$$ N ∗ and $$\Delta $$ Δ resonances is extracted in terms of pole positions and residues. We discuss the impact of the $$\gamma p\rightarrow K\Sigma $$ γ p → K Σ channels in detail and investigate the influence of recent polarization data for $$\eta p$$ η p photoproduction.
