TL;DR: In this article, an ab initio calculation of the neutron distribution of the Neutron-rich nucleus Ca-48 is presented, and it is shown that the difference between the radii of the neutrons and proton distributions is significantly smaller than previously thought.
Journal ArticleDOI
Realistic calculations of KNN, KNNN, and KKNN quasibound states
TL;DR: In this article, the binding energies and widths of three-body K ¯ N N N, and of four-body k ¯ N n N N and K ¯ K ¯ n N n nuclear quasibounded states are calculated in the hyperspherical basis, using realistic NN potentials and subthreshold energy dependent chiral K¯ N interactions.
Journal ArticleDOI
Effective Field Theory for Lattice Nuclei
TL;DR: It is argued that pionless EFT is the appropriate theory to describe the light nuclei obtained in LQCD simulations carried out at pion masses heavier than the physical pion mass.
Journal ArticleDOI

TL;DR: The results support the high-resolution description of high-momentum states being predominantly due to nucleons in SRC pairs, and compare to theoretical generalized contact formalism cross-section calculations show good agreement using both phenomenological and chiral nucleon-nucleon potentials.
Journal ArticleDOI
Generalized nuclear contacts and momentum distributions
TL;DR: In this paper, the general nuclear contact matrices are defined, taking into consideration all partial waves and finite-range interactions, extending Tan's work on the zero range model, and the relations between the contacts and the one-nucleon and two-Nucleon momentum distributions are derived.
