On ambiguities of sign determination of the S-matrix from energy levels in a finite box
E. Oset
In a recent paper the authors make a study on the determination of the S-matrix elements for scattering of particles in the infinite volume from the energy levels in the finite box…
Finite volume treatment of pi pi scattering and limits to phase shifts extraction from lattice QCD
M. Albaladejo, J. A. Oller, E. Oset +2
We study theoretically the effects of finite volume for pipi scattering in order to extract physical observables for infinite volume from lattice QCD. We compare three different ap…
Scalar mesons moving in a finite volume and the role of partial wave mixing
M. Döring, U. -G. Meißner, E. Oset +1
Phase shifts and resonance parameters can be obtained from finite-volume lattice spectra for interacting pairs of particles, moving with nonzero total momentum. We present a simple…
Strategy to find the two states from lattice QCD simulations
A. Martínez Torres, M. Bayar, D. Jido +1
Theoretical studies within the chiral unitary approach, and recent experiments, have provided evidence of the existence of two isoscalar states in the region of the . In t…
The pion-pion Interaction in the rho Channel in Finite Volume
Hua-Xing Chen, E. Oset
The aim of this paper is to investigate an efficient strategy that allows to obtain pi-pi phase shifts and rho meson properties from QCD lattice data with high precision. For this…
Scattering of unstable particles in a finite volume: the case of pi rho scattering and the a1(1260) resonance
L. Roca, E. Oset
We present a way to evaluate the scattering of unstable particles quantized in a finite volume with the aim of extracting physical observables for infinite volume from lattice data…
