Hadron resonances, large Nc, and the half-width rule
Enrique Ruiz Arriola, Wojciech Broniowski, Pere Masjuan
We suggest using the half-width rule to make an estimate of the 1/Nc errors in hadronic models containing resonances. We show simple consequences ranging from the analysis of meson…
Renormalized Quarkonium
J. Segovia, D. R. Entem, F. Fernández +1
We extend our previous study of the vector charmonium states within a renormalization approach with boundary conditions to the full spectrum of charmonium and bottomonium. On the l…
Meson dominance of hadron form factors and large-Nc phenomenology
Pere Masjuan, Enrique Ruiz Arriola, Wojciech Broniowski
We discuss the pion and nucleon form factors and generalized form factors within the large-Nc approach in the space-like region. We estimate their theoretical uncertainties through…
The hadron resonance gas model: thermodynamics of QCD and Polyakov loop
E. Megias, E. Ruiz Arriola, L. L. Salcedo
We study the hadron resonance gas model and describe the equation of state of QCD and the vacuum expectation value of the Polyakov loop in the confined phase, in terms of hadronic…
From Chiral quark dynamics with Polyakov loop to the hadron resonance gas model
E. Ruiz Arriola, E. Megias, L. L. Salcedo
Chiral quark models with Polyakov loop at finite temperature have been often used to describe the phase transition. We show how the transition to a hadron resonance gas is realized…
The Polyakov loop and the hadron resonance gas model
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The Polyakov loop has been used repeatedly as an order parameter in the deconfinement phase transition in QCD. We argue that, in the confined phase, its expectation value can be re…
Systematics of radial and angular-momentum Regge trajectories of light non-strange q\bar{q}-states
Pere Masjuan, Enrique Ruiz Arriola, Wojciech Broniowski
We reanalyze the radial (n) and angular-momentum (J) Regge trajectories for all light-quark states with baryon number zero listed in the 2011 edition of the Particle Data Tables. T…
Error estimates on Nuclear Binding Energies from Nucleon-Nucleon uncertainties
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
Despite great theoretical efforts the NN interaction can only be determined with a finite precision, implying an error upper bound for nuclear masses. We analyze for the first time…
