Baryon-baryon interactions from Effective Field Theory
EPJ Web of Conferences, 2010 I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S = −3 to −4 baryon-baryon systems ...

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 ...

The V-QCD baryon: numerical solution and baryon spectrum
Journal of High Energy Physics, 2023 The single baryon solution of V-QCD is numerically computed. The spectrum of spin and isospin modes is also computed by quantizing the light fluctuations around the baryon.

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.

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 than the baryon-baryon interaction. Sea quarks play a minor important role.

Baryon operators and baryon spectroscopy [PDF]
Nuclear Physics B - Proceedings Supplements, 2006 The issues involved in a determination of the baryon resonance spectrum in lattice QCD are discussed. The variational method is introduced and the need to construct a sufficient basis of interpolating operators is emphasised. The construction of baryon operators using group-theory techniques is outlined.

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 J π = 1/2 +
