Heavy Quark Spin Symmetry and Heavy Baryons: Electroweak Decays
C. Albertus, J. E. Amaro, E. Hernandez +1
Heavy quark spin symmetry is discussed in the context of single and doubly heavy baryons. A special attention is paid to the constraints/simplifications that this symmetry imposes…
Wave functions for dynamically generated resonances; the two and
J. Yamagata-Sekihara, J. Nieves, E. Oset
In this work we develop a formalism to evaluate wave functions in momentum and coordinate space for the resonant states dynamically generated in a unitary coupled channel approach.…
Strange and charm mesons at FAIR
L. Tolos, D. Cabrera, D. Gamermann +5
We study the properties of strange and charm mesons in hot and dense matter within a self-consistent coupled-channel approach for the experimental conditions of density and tempera…
Meson Resonances at large Nc: Complex Poles vs Breit-Wigner Masses
J. Nieves, E. Ruiz Arriola
The rigorous quantum mechanical definition of a resonance requires determining the pole position in the second Riemann sheet of the analytically continued partial wave scattering a…
Properties of the rho and sigma Mesons from Unitary Chiral Dynamics
J. Nieves, E. Ruiz Arriola
The chiral limit of the rho and sigma masses and widths is discussed. We work within the inverse amplitude method to one loop in SU(2) ChPT and analyze the consequences that all ch…
Neutrino Induced Coherent Pion Production off Nuclei and PCAC
E. Hernández, J. Nieves, M. J. Vicente-Vacas
We review the Rein--Sehgal model and criticize its use for low energy neutrino induced coherent pion production. We have studied the validity of the main approximations implicit in…
