Spectrum of three-body bound states in a finite volume
Ulf-G. Meißner, Guillermo Ríos, Akaki Rusetsky
The spectrum of a bound state of three identical particles with a mass in a finite cubic box is studied. It is shown that in the unitary limit, the energy shift of a shallow bo…
Bound states on the lattice with partially twisted boundary conditions
D. Agadjanov, F. -K. Guo, G. Ríos +1
We propose a method to study the nature of exotic hadrons by determining the wave function renormalization constant from lattice simulations. It is shown that, instead of study…
Remarks on pole trajectories for resonances
C. Hanhart, J. R. Pelaez, G. Rios
We discuss in general terms pole trajectories of resonances coupling to a continuum channel as some strength parameter is varied. It is demonstrated that, regardless the underlying…
Finite volume treatment of scattering in the channel
M. Albaladejo, G. Rios, J. A. Oller +1
We make a theoretical study of scattering with quantum numbers in a finite box. To calculate physical observables for infinite volume from lattice QCD, the fin…
Nucleon-Nucleon scattering from the dispersive N/D method: next-to-leading order study
Zhi-Hui Guo, J. A. Oller, G. Rios
We consider nucleon-nucleon () interactions from Chiral Effective Field Theory applying the method. The dynamical input is given by the discontinuity of the partial-…
Determination of Chiral Perturbarion Theory low energy constants from a precise description of pi-pi scattering threshold parameters
Guillermo Rios, Jenifer Nebreda, Jose R. Pelaez
We report on our determination of the values of the one and two loop low energy constants appearing in the Chiral Perturbation Theory calculation of the pi-pi scattering amplitude.…
