Relativistic distorted-wave analysis of the missing-energy spectrum measured with monochromatic -C interactions at JSNS
J. M. Franco-Patino, J. García-Marcos, V. Belocchi +3
Recently, the JSNS collaboration measured for the first time the missing-energy distribution of C using a monochromatic neutrino beam coming from kaon decays at rest. In…
The Be photodisintegration cross section within Cluster Effective Field Theory
Ylenia Capitani, Elena Filandri, Chen Ji +2
A low-energy calculation of Be photodisintegration cross section is presented within an cluster approach. The and contact interactions are derived from cluste…
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…

M. Viviani, L. Girlanda, A. Kievsky +2
We present a theoretical study of the processes d(d,p)3H and d(d,n)3He at energies of interest for energy production and for big-bang nucleosynthesis. We accurately solve the four…
Effect of short- and long-range correlations on neutron skins of various neutron-rich doubly magic nuclei
G. Co', M. Anguiano, A. M. Lallena
We study the effects of correlations beyond the independent particle model in the evaluation of neutron skins of various neutron-rich doubly magic nuclei. We consider short- and lo…
Charge radii of Ca isotopes and correlations
G. Co', M. Anguiano, A. M. Lallena
We study the effects of short- and long-range correlations on the charge radii of Ca isotopes. We start our investigation with an independent particle model consisting in Hartree-F…
Tensor force and deformation in even-even nuclei
G. Co, M. Anguiano, A. M. Lallena
The variational principle is used to build a model which describes open shell nuclei with ground state deformations. Hartree-Fock equations are solved by using single particle wave…
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…
Efimov Physics and Connections to Nuclear Physics
A. Kievsky, L. Girlanda, M. Gattobigio +1
Physical systems characterized by a shallow two-body bound or virtual state are governed at large distances by a continuous-scale invariance, which is broken to a discrete one when…
Two- and three-nucleon contact interactions and ground-state energies of light- and medium-mass nuclei
R. Schiavilla, L. Girlanda, A. Gnech +5
Classes of two-nucleon () contact interactions are developed in configuration space at leading order (LO), next-to-leading order (NLO), and next-to-next-to-next-to-leading orde…
Unitary ambiguity of NN contact interactions and the 3N force
L. Girlanda, A. Kievsky, L. E. Marcucci +1
We identify a redundancy between two- and three-nucleon contact interactions at the fourth and fifth order of the chiral expansion respectively. In particular we show that tensor-t…
Parity- and time-reversal-violating nuclear forces
J. de Vries, E. Epelbaum, L. Girlanda +3
Parity-violating and time-reversal conserving (PVTC) and parity-violating and time-reversal-violating (PVTV) forces in nuclei form only a tiny component of the total interaction be…
Nuclear structure uncertainties in coherent elastic neutrino-nucleus scattering
G. Co', M. Anguiano, A. M. Lallena
The effects of the nuclear structure uncertainties on the description of processes induced by coherent scattering of neutrinos on nuclei are investigated. A reference calculation b…

L. E. Marcucci, J. Dohet-Eraly, L. Girlanda +3
The Hyperspherical Harmonics (HH) method is one of the most accurate techniques to solve the quantum mechanical problem for nuclear systems with . In particular, by applyin…

Correlations imposed by the unitary limit between few-nucleon systems, nuclear matter and neutron stars
A. Kievsky, M. Viviani, D. Logoteta +2
The large values of the singlet and triplet two-nucleon scattering lengths locate the nuclear system close to the unitary limit. This particular position strongly constrains the lo…
