The 3- and 4- particle systems within short-range Effective Field Theory
E. Filandri, M. Viviani, L. Girlanda +2
and nuclei represent essential elements for life on Earth. The study of their formation plays a key role in understanding heavy element nucleosynt…
The X17 boson and the d(p,e+ e-)3He and d(n,e+ e-)3H processes: a theoretical analysis
M. Viviani, E. Filandri, L. Girlanda +3
The present work deals with the e+ e- pair production in the d(p,e+e-)3He and d(n,e+ e-)3H processes, in order to evidentiate possible effects due to the exchange of a hypothetical…
Momentum dependent nucleon-nucleon contact interactions and their effect on p-d scattering observables
E. Filandri, L. Girlanda, A. Kievsky +2
Starting from a complete set of relativistic nucleon-nucleon contact operators up to order of the expansion in the soft (relative or nucleon) momentum , we show that no…
Relativistic constraints on 3N contact interactions
Alessia Nasoni, Elena Filandri, Luca Girlanda
In this paper we analyze the relativistic corrections to the leading order three-nucleon (3N) contact interactions. These boost corrections are derived first from the nonrelativist…
Momentum dependent nucleon-nucleon contact interaction from a relativistic Lagrangian
E. Filandri, L. Girlanda
A complete set of parity- and time-reversal conserving relativistic nucleon-nucleon contact operators is identified up to the order of the expansion in soft momenta . A…
Effect of the N3LO three-nucleon contact interaction on p-d scattering observables
L. Girlanda, E. Filandri, A. Kievsky +2
A unitary transformation allows to remove redundant terms in the two-nucleon (2N) contact interaction at the fourth order (N3LO) in the low-energy expansion of Chiral Effective Fie…
The X17 boson and the HHe and HeHe processes: a theoretical analysis
M. Viviani, E. Filandri, L. Girlanda +4
The present work deals with - pair production in the four-nucleon system. We first analyze the process as a purely electromagnetic one in the context of a state-of-the-ar…
