A high-precision variational approach to three- and four-nucleon bound and zero-energy scattering states
A. Kievsky, S. Rosati, M. Viviani +2
The hyperspherical harmonic (HH) method has been widely applied in recent times to the study of the bound states, using the Rayleigh-Ritz variational principle, and of low-energy s…
On a redundancy in the parity-violating 2-nucleon contact Lagrangian
Luca Girlanda
It is shown that the number of independent operators in the nucleon-nucleon parity-violating contact Lagrangian at the leading order in the low-momentum expansion, can be reduced t…
Bakamjian-Thomas mass operator for the few-nucleon system from chiral dynamics
L. Girlanda, W. H. Klink, M. Viviani
We present an exploratory study consisting in the formulation of a relativistic quantum mechanics to describe the few-nucleon system at low energy, starting from the quantum field…
Relationship between the quark condensate and low-energy Pi-Pi observables beyond O(p^4)
Luca Girlanda
The two-flavor Gell-Mann-Oakes-Renner ratio is expressed in terms of low-energy pi-pi observables including the O(p^6) double chiral logarithms, computed in Generalized Chiral Pert…
