We use a chiral constituent quark model to study possible molecular structures in the heavy baryon spectrum. We first analyze D*N states and we find a bound state in the JP = 3/2- sector with an small binding energy. This state can be identified with the Λc(2940)+. The decays of this state are compatible with the existent experimental data. As a by product a state is predicted in the bottom baryon spectrum as a [Formula: see text] state with a mass around 6250 MeV. Moreover we also analyze other DN, D*N, DΔ and D*Δ states and their analogs in the bottom baryon sector finding several bound states.

Abstract In this work, we extended our statistical model with charmed and bottomed hadrons, and fit the quark creational probabilities for the heavy quarks, using low energy inclusive charmonium and bottomonium data. With the finalized fit for all the relevant types of quarks (up, down, strange, charm, bottom) at the energy range from a few GeV up to a few tens of GeV’s, the model is now considered complete. Some examples are also given for proton–proton, pion–proton, and proton–antiproton collisions with charmonium, bottomonium, and open charm hadrons in the final state.

Even though quantum chromodynamics is a broken conformal theory, the AdS/CFT correspondence has led to important insights into the properties of QCD. For example, as shown by Polchinski and Strassler, dimensional counting rules for the power-law falloff of hadron scattering amplitudes follow from dual holographic models with conformal behavior at short distances and confinement at large distances. We find that one also obtains a remarkable representation of the entire light-quark meson and baryon spectrum, including all orbital excitations, based on only one mass parameter. We also show how hadron light-front wavefunctions and hadron form factors in both the space-like and time-like regions can be predicted.
