“…The influence of different nucleon resonances has been tested by means of a PWA using the Bo-Ga PWA framework. The best solution was obtained by including the initial p+p configurations 1 S 0 , 3 P 0 , 3 P 1 , 3 P 2 , 1 D 2 and 3 Recently, the HADES setup has been upgraded by an electromagnetic calorimeter (ECAL) and a Forward Detector (FD) based on PANDA experiment straw tubes [46]. The new data that was collected in February 2022 offers the opportunity to perform the same measurement with an upgraded setup at a higher proton beam energy of 4.5 GeV.…”

The production of $$\Sigma ^{0}$$ Σ 0 hyperons in proton proton collisions at a beam kinetic energy of 3.5 GeV impinging on a liquid hydrogen target was investigated using data collected with the HADES setup. The total production cross section is found to be $${\sigma (pK^{+}\Sigma ^{0}) = 17.7 \pm 1.7 (stat) \pm 1.6 (syst)}$$ σ ( p K + Σ 0 ) = 17.7 ± 1.7 ( s t a t ) ± 1.6 ( s y s t ) µb. Differential cross section distributions of the exclusive channel $${pp \rightarrow pK^{+}\Sigma ^{0}}$$ p p → p K + Σ 0 were analyzed in the center-of-mass, Gottfried–Jackson and helicity reference frames for the first time at the excess energy of 556 MeV. The data support the interplay between pion and kaon exchange mechanisms and clearly demonstrate the contribution of interfering nucleon resonances decaying to $$\textrm{K}^{+}\Sigma ^{0}$$ K + Σ 0 . The Bonn–Gatchina partial wave analysis was employed to analyse the data. Due to the limited statistics, it was not possible to obtain an unambiguous determination of the relative contribution of intermediate nucleon resonances to the final state. However nucleon resonances with masses around 1.710 $${\textrm{GeV}/\textrm{c}^{2}}$$ GeV / c 2 ($${\textrm{N}^{*}(1710)}$$ N ∗ ( 1710 ) ) and 1.900 $${\textrm{GeV}/\textrm{c}^{2}}$$ GeV / c 2 ($${\textrm{N}^{*}(1900)}$$ N ∗ ( 1900 ) or $${\Delta ^{*}(1900)}$$ Δ ∗ ( 1900 ) ) are preferred by the fit.

The detector has been recently upgraded by a large area electromagnetic calorimeter and a forward detector (for a recent review see [52]) extending the coverage to very forward region (0.5 • < θ < 7.5 • ). These upgrades allow to measure hadron decays involving photons and significantly improve acceptance for protons and hyperons which at these energies are emitted to large extent in forward directions.…”

We evaluate the cross section for the pp → pp f 1 (1285) and p p → p p f 1 (1285) reactions at near threshold energies relevant for the HADES and PANDA experiments at GSI-FAIR. We assume that at energies close to the threshold the ωω → f 1 (1285) and ρ 0 ρ 0 → f 1 (1285) fusion processes are the dominant production mechanisms. The vertex for the VV → f 1 coupling is derived from an effective coupling Lagrangian. The g ρρ f 1 coupling constant is extracted from the decay rate of f 1 (1285) → ρ 0 γ using the vector-meson-dominance ansatz. We assume g ωω f 1 = g ρρ f 1 , equality of these two coupling constants, based on arguments from the naive quark model and vectormeson dominance. The amplitude for the VV → f 1 fusion, supplemented by phenomenological vertex form factors for the process, is given. The differential cross sections at energies close to the threshold are calculated. In order to determine the parameters of the model the γp → f 1 (1285)p reaction is discussed in addition and results are compared with the CLAS data. The possibility of a measurement by HADES@GSI is presented and discussed. We performed a Monte Carlo feasibility simulations of the pp → pp f 1 reaction for √ s = 3.46 GeV in the π + π − π + π − (not shown explicitly) and π + π − π + π − π 0 final states using the PLUTO generator. The latter one is especially promising as a peak in the π + π − η should be observable by HADES.
