Heavy-Light Mesons on the Light Front

Shuo Tang, Yang Li, Pieter Maris +1

We study the heavy-light mesons within basis light-front quantization. The resulting mass spectra of , , , and agree reasonably well with experiments. We also pred…

From bound states to the continuum

Calvin W. Johnson, Kristina D. Launey, Naftali Auerbach +35

This white paper reports on the discussions of the 2018 Facility for Rare Isotope Beams Theory Alliance (FRIB-TA) topical program "From bound states to the continuum: Connecting bo…

Probing ab initio emergence of nuclear rotation

M. A. Caprio, P. J. Fasano, P. Maris +2

Structural phenomena in nuclei, from shell structure and clustering to superfluidity and collective rotations and vibrations, reflect emergent degrees of freedom. Ab initio theory…

Minkowski-space solutions of the Schwinger-Dyson equation for the fermion propagator with the rainbow-ladder truncation

Shaoyang Jia, Pieter Maris, Dyana C. Duarte +3

We solve the Minkowski-space Schwinger-Dyson equation (SDE) for the fermion propagator in quantum electrodynamics (QED) with massive photons. Specifically, we work in the quenched…

Valence structures of light and strange mesons from the basis light-front quantization framework

Shaoyang Jia, James P. Vary

We apply the basis light-front quantization framework to solve for the structures of mesons with light and strange valence quarks. Our approach treats mesons as relativistic bound…

Basis Light-Front Quantization for a Chiral Nucleon-Pion Lagrangian

Weijie Du, Yang Li, Xingbo Zhao +2

We present the first application of the Basis Light-Front Quantization method to a simple chiral model of the nucleon-pion system as a relativistic bound state for the physical pro…

Parton Distribution Functions of Heavy Mesons on the Light Front

Jiangshan Lan, Chandan Mondal, Meijian Li +4

The parton distribution functions (PDFs) of heavy mesons are evaluated from their light-front wave functions, which are obtained from a basis light-front quantization in the leadin…

Sub Coulomb barrier d+Pb scattering in the time-dependent basis function approach

Peng Yin, Weijie Du, Wei Zuo +2

We employ the non-perturbative time-dependent basis function (tBF) approach to study the scattering of the deuteron on Pb below the Coulomb barrier. We obtain the bound and…

Benchmark neutrinoless double-beta decay matrix elements in a light nucleus

R. A. M. Basili, J. M. Yao, J. Engel +4

We compute nuclear matrix elements of neutrinoless double-beta decay mediated by light Majorana-neutrino exchange in the A = 6 system. The goal is to benchmark two many-body approa…

Pion and kaon parton distribution functions from basis light front quantization and QCD evolution

Jiangshan Lan, Chandan Mondal, Shaoyang Jia +2

We investigate the parton distribution functions (PDFs) of the pion and the kaon by combining quantum chromodynamics (QCD) evolution with the basis light front quantization. The in…

Frame dependence of transition form factors in light-front dynamics

Meijian Li, Yang Li, Pieter Maris +1

We calculate the transition form factor between vector and pseudoscalar quarkonia in both the timelike and the spacelike region using light-front dynamics. We investigate the frame…
