“…It is clear that this potential has no D-waves. However, D-waves are automatically generated where this Lagrangian is reinterpreted by means of the local hidden gauge approach [78][79][80] and is generated by the exchange of a light vector meson (ρ meson for the KK * interaction). In this case one has the explicit ρ propagator and the potential becomes…”

Lattice QCD simulations provide a promising way to disentangle different interpretations of hadronic resonances, which might be of particular relevance to understand the nature of the so-called XY Z particles. Recent studies have shown that in addition to the well-established naive quark model picture, the axial-vector meson f 1 (1285) can also be understood as a dynamically generated state built upon the KK * interaction. In this work, we calculate the energy levels of the KK * system in the f 1 (1285) channel in finite volume using the chiral unitary approach. We propose to calculate the loop function in the dimensional regularization scheme, which is equivalent to the hybrid approach adopted in previous studies. We also study the inverse problem of extracting the bound state information from synthetic lattice QCD data and comment on the difference between our approach and the Lüscher method. *

“…Our formalism, however, is non-relativistic so that uniform baryon motion cannot be ignored in a generic reference frame. The Breit frame is the correct one to compute form factors [4]. whereμ = 1, 2, 3, 5; similarly for the U(2) L gauge fields.…”

In a simple holographic model for QCD in which the Chern-Simons term is incorporated to take into account the QCD chiral anomaly, we show that baryons arise as stable solitons which are the 5D analogs of 4D skyrmions. Contrary to 4D skyrmions and previously considered holographic scenarios, these solitons have sizes larger than the inverse cut-off of the model, and therefore they are predictable within our effective field theory approach. We perform a numerical determination of several static properties of the nucleons and find a satisfactory agreement with data. We also calculate the amplitudes of "anomalous" processes induced by the Chern-Simons term in the meson sector, such as ω → πγ and ω → 3π. A combined fit to baryonic and mesonic observables leads to an agreement with experiments within 16%.

We use a modified version of the Skyrme model in which the stabilizing fourth-order term is separated in two parts with different parameters that are introduced in the Lagrangian and could vary independently. The predictions for the static properties of baryons are calculated and results are compared with the respective experimental values and those of other authors. We show that it possible to improve in an expressive way the results for the set of the important quantities at the same time.
