Two-body scattering states in Minkowski space and the Nakanishi integral representation onto the null plane
Tobias Frederico, Giovanni Salmè, Michele Viviani
The Nakanishi perturbative integral representation of the four-dimensional T-matrix is investigated in order to get a workable treatment for scattering states, solutions of the inh…
Theoretical description of three- and four-nucleon scattering states using bound-state-like wave functions
A. Kievsky, M. Viviani, L. E. Marcucci
Bound-state-like wave functions are used to determine the scattering matrix corresponding to low energy and He collisions. To this end, the coupled channel form of the…
Chiral effective field theory predictions for muon capture on deuteron and 3He
L. E. Marcucci, A. Kievsky, S. Rosati +2
The muon-capture reactions 2H(μ^-,ν_μ)nn and 3He(μ^-,ν_μ)3H are studied with nuclear strong-interaction potentials and charge-changing weak currents, derived in chiral effective fi…
The two-nucleon electromagnetic charge operator in chiral effective field theory (EFT) up to one loop
S. Pastore, L. Girlanda, R. Schiavilla +1
The electromagnetic charge operator in a two-nucleon system is derived in chiral effective field theory (EFT) up to order (or N4LO), where denotes the low-momentum s…
Subleading contributions to the three-nucleon contact interaction
L. Girlanda, A. Kievsky, M. Viviani
We obtain a minimal form of the two-derivative three-nucleon contact Lagrangian, by imposing all constraints deriving from discrete symmetries, Fierz identities and Poincare' covar…
General integral relations for the description of scattering states using the hyperspherical adiabatic basis
C. Romero-Redondo, E. Garrido, P. Barletta +2
In this work we investigate 1+2 reactions within the framework of the hyperspherical adiabatic expansion method. To this aim two integral relations, derived from the Kohn variation…
