Trends and Progress in Nuclear and Hadron Physics: a straight or winding road

James P. Vary, Lekha Adhikari, Guangyao Chen +8

Quantitative calculations of the properties of hadrons and nuclei, with assessed uncertainties, have emerged as competitive with experimental measurements in a number of major case…

Quarkonium wave functions on the light front

Yang Li

We study heavy quarkonium within the light-front Hamiltonian formalism. Our effective Hamiltonian is based on the holographic QCD confining potential and the one-gluon exchange int…

Diffractive charmonium spectrum in high energy collisions in the basis light-front quantization approach

Guangyao Chen, Yang Li, Pieter Maris +2

Using the charmonium light-front wavefunctions obtained by diagonalizing an effective Hamiltonian with the one-gluon exchange interaction and a confining potential inspired by ligh…

Shell Model States in the Continuum

A. M. Shirokov, A. I. Mazur, I. A. Mazur +1

We suggest a method for calculating scattering phase shifts and energies and widths of resonances which utilizes only eigenenergies obtained in variational calculations with oscill…

Prediction for a four-neutron resonance

A. M. Shirokov, G. Papadimitriou, A. I. Mazur +3

We utilize various {\em ab initio} approaches to search for a low-lying resonance in the four-neutron () system using the JISP16 realistic interaction. Our most accurate p…

Ab initio no-core solutions for Li

Ik Jae Shin, Youngman Kim, Pieter Maris +4

We solve for properties of Li in the ab initio No-Core Full Configuration approach and we separately solve for its ground state and resonance with the Gamow She…

Natural orbital description of the halo nucleus 6He

Ch. Constantinou, M. A. Caprio, J. P. Vary +1

Ab initio calculations of nuclei face the challenge of simultaneously describing strong short-range internucleon correlations and the long-range properties of weakly-bound halo nuc…

N3LO NN interaction adjusted to light nuclei in ab exitu approach

A. M. Shirokov, I. J. Shin, Y. Kim +3

We use phase-equivalent transformations to adjust off-shell properties of similarity renormalization group evolved chiral effective field theory NN interaction (Idaho N3LO) to fit…

Early Time Dynamics of Gluon Fields in High Energy Nuclear Collisions

Joseph I. Kapusta, Guangyao Chen, Rainer J. Fries +1

Nuclei colliding at very high energy create a strong, quasi-classical gluon field during the initial phase of their interaction. We present an analytic calculation of the initial s…

nuclear many-body perturbation calculations in the Hartree-Fock basis

Baishan Hu, Furong Xu, Zhonghao Sun +2

Starting from realistic nuclear forces, the chiral NLO and JISP16, we have applied many-body perturbation theory (MBPT) to the structure of closed-shell nuclei, He and $^{1…

In-medium covariant propagator of baryons under a strong magnetic field: effect of the intrinsic magnetic moments

R. M. Aguirre, A. L. De Paoli

We obtain the covariant propagator at finite temperature for interacting baryons immersed in a strong magnetic field. The effect of the intrinsic magnetic moments on the Green func…

Form Factors and Generalized Parton Distributions in Basis Light-Front Quantization

Lekha Adhikari, Yang Li, Xingbo Zhao +3

We calculate the elastic form factors and the Generalized Parton Distributions (GPDs) for four low-lying bound states of a demonstration fermion-antifermion system, strong coupling…

Efficacy of the SU(3) scheme for ab initio large-scale calculations beyond the lightest nuclei

T. Dytrych, P. Maris, K. D. Launey +7

We report on the computational characteristics of ab initio nuclear structure calculations in a symmetry-adapted no-core shell model (SA-NCSM) framework. We examine the computation…

Ab initio no-core properties of 7Li and 7Be with JISP16 and NNLO_opt interactions

Taihua Heng, James P. Vary, Pieter Maris

We investigate the properties of 7Li with the JISP16 and chiral NNLO_opt nucleon-nucleon interactions and 7Be with the JISP16 interaction in the ab initio no-core full configuratio…
