Meson-meson correlations in baryon-baryon and antibaryon-baryon interactions [PDF]
Progress in Particle and Nuclear Physics, 1995 Recent work of the J\"ulich group about the role of meson-meson correlations in baryon-baryon and antibaryon-baryon interactions is reviewed.Comment: Lecture given at the Erice School 1995, TEX, 10 pages, 15 ...

Theoretical Nuclear Physics in Italy, 2002 A review of the theoretical activity in Italy in the research field of Hadronic Physics is given. Specific focus is put on phenomenological models based on the effective degrees of freedom of constituent quarks, on parton distributions in hard processes ...

Baryon-Baryon Potentials on the Lattice [PDF]
Physics Letters B, 1993 The interaction of spatially extended heavy baryons is investigated in the framework of lattice QCD with dynamical quarks. It is shown that the expected dipole forces have a very short range and that the baryon-antibaryon interaction is more attractive ...

The allowed baryon to baryon–meson strong transitions
European Physical Journal C: Particles and FieldsWe investigate the kinematically allowed baryon to baryon–meson strong transitions in all the light and heavy sectors. We consider only the ground state on-shell particles in the baryonic and mesonic channels.

The baryon-baryon interaction in the large- N c limit. [PDF]
Eur Phys J A Hadron NuclAbstract We analyze the large- $$N_c$$ N c structure of the baryon–baryon potential derived in the framework of SU(3) chiral perturbation theory up to next-to-leading order ...

Baryon–anti-Baryon photoproduction [PDF]
AIP Conference Proceedings, 2020 Baryon - anti-baryon photoproduction off a proton target is being studied in detail at Jefferson Lab with the GlueX Experiment. We observe $p\bar{p}$ and, for the first time, $Λ\barΛ$ photoproduction (with $Λ\rightarrow π^- p$, $\barΛ \rightarrow π^+ \bar{p}$) from thresholds up to $E_γ = 11.4$ GeV.

International Journal of Modern Physics: Conference Series, 2014 We study odd-parity baryonic resonances with one heavy and three light flavors, dynamically generated by meson-baryon interactions. Special attention is paid to Heavy Quark Spin Symmetry (HQSS), hence pseudoscalar and vector mesons and baryons with Jπ = 1/2+ and 3/2+ are considered as constituent hadrons.

Meson baryon components in the states of the baryon decuplet [PDF]
EPJ Web of Conferences, 2014 We extend the Weinberg compositeness condition to partial waves of L = 1 and resonant states to determine the weight of meson-baryon component in the [Formula: see text] baryon decuplet. We obtain an appreciable weight of πN in the Δ(1232) wave function, of the order of 60 % and we also show that, as we go to higher energies in the members of the ...

Light particles with baryon and lepton numbers
Physics Letters B, 2021 We consider light new particles χ and ϕ that carry baryon and lepton numbers. If these particles are lighter than nucleons they lead to exotic decays such as p→π+χ and p→e+ϕ, not yet fully constrained by dedicated searches.
