Thermal shifts, fluctuations, and missing states
Enrique Ruiz Arriola, Wojciech Broniowski, Eugenio Megias +1
Thermal shifts and fluctuations at finite temperature below the deconfinement crossover from hadronic matter to the quark-gluon plasma provide a viable way to search for missing st…
Coarse grained short-range correlations
I. Ruiz Simo, R. Navarro Perez, J. E. Amaro +1
We develop a scheme to take into account the effects of short-range nucleon-nucleon correlations in the nucleon-pair wave function by solving the Bethe-Goldstone equation for a coa…
Phase transition in the SRG flow of nuclear interactions
Varese S. Timoteo, Enrique R. Arriola, S. Szpigel
We use a chiral interaction at N3LO in the 1S0 channel of the nucleon- nucleon interaction in order to investigate the on-shell transition along the similarity renormalization grou…
Heavy Quark Coupled Channel Dynamics from Thermal Shifts
Enrique Ruiz Arriola, Lorenzo Luis Salcedo, Eugenio Megias
QCD at finite temperature below the phase transition should be determined in terms of colour singlet states such as hadrons and strings. We show how quark-hadron duality allows ext…
The falsification of Chiral Nuclear Forces
E. Ruiz Arriola, J. E. Amaro, R. Navarro Perez
Predictive power in theoretical nuclear physics has been a major concern in the study of nuclear structure and reactions. The Effective Field Theory (EFT) based on chiral expansion…
Proton-proton hollowness at the LHC from inverse scattering
Enrique Ruiz Arriola, Wojciech Broniowski
Parameterizations of the pp scattering data at the LHC collision energies indicate a hollow in the inelasticity profile of the pp interaction, with less absorption for head-on coll…
Some Three-body force cancellations in Chiral Lagrangians
E. Ruiz Arriola
The cancellation between off-shell two body forces and three body forces implies a tremendous simplification in the study of three body resonances in two meson-one baryon systems.…
Three pion nucleon coupling constants
E. Ruiz Arriola, J. E. Amaro, R. Navarro Perez
There exist four pion nucleon coupling constants, , , and which coincide when up and down quark masses a…
Precise Determination of Charge Dependent Pion-Nucleon-Nucleon Coupling Constants
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
We undertake a covariance error analysis of the pion-nucleon-nucleon coupling constants from the Granada-2013 np and pp database comprising a total of 6720 scattering data below LA…
Heavy Quark Entropy shift: From the Hadron Resonance Gas to Power Corrections
E. Megias, E. Ruiz Arriola, L. L. Salcedo
A heavy quark placed in the medium modifies its specific heat. Using a renormalization group argument we show a low energy theorem in terms of the defect in the trace of the energy…
Binding in light nuclei: Statistical NN uncertainties vs Computational accuracy
R. Navarro Perez, A. Nogga, J. E. Amaro +1
We analyse the impact of the statistical uncertainties of the the nucleon-nucleon interaction, based on the Granada-2013 np-pp database, on the binding energies of the triton and t…
Proton-Proton On Shell Optical Potential at High Energies and the Hollownes Effect
Enrique Ruiz Arriola, Wojciech Broniowski
We analyze the usefulness of the optical potential as suggested by the double spectral Mandelstam representation at very high energies, such as in the proton-proton scattering at I…
Heavy quark-antiquark free energy and thermodynamics of string-hadron avoided crossings
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The correlation function between two Polyakov loops encodes the free-energy shift due to a pair of separated colour conjugated sources in the hot QCD medium. This is analyzed in te…
Uncertainty quantification of effective nuclear interactions
R. Navarro Perez, J. E. Amaro, E. Ruiz Arriola
We give a brief review on the development of phenomenological NN interactions and the corresponding quantification of statistical uncertainties. We look into the uncertainty of eff…
Fixed points of the SRG evolution and the on-shell limit of the nuclear force
E. Ruiz Arriola, S. Szpigel, V. S. Timoteo
We study the infrared limit of the similarity renormalization group (SRG) using a simple toy model for the nuclear force aiming to investigate the fixed points of the SRG evolution…
