Identification of non-ordinary mesons from the dispersive connection between their poles and their Regge trajectories: the f0(500) resonance
J. T. Londergan, J. Nebreda, J. R. Pelaez +1
We show how the Regge trajectory of a resonance can be obtained from its pole in a scattering process and analytic constraints in the complex angular momentum plane. The method is…
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.…
Varying the light quark mass: impact on the nuclear force and Big Bang nucleosynthesis
J. C. Berengut, E. Epelbaum, V. V. Flambaum +4
The quark mass dependences of light element binding energies and nuclear scattering lengths are derived using chiral perturbation theory in combination with non-perturbative method…
