Chiral effective field theory (chi EFT) provides a systematic approach to describe low-energy nuclear forces. Moreover, chi EFT is able to provide well-founded estimates of statistical and systematic uncertainties-although this unique advantage has not yet been fully exploited. We fill this gap by performing an optimization and statistical analysis of all the low-energy constants (LECs) up to next-to-next-to-leading order. Our optimization protocol corresponds to a simultaneous fit to… 

Chiral Interactions up to Next-to-Next-to-Next-to-Leading Order and Nuclear Saturation.

An efficient Monte Carlo framework for perturbative calculations of infinite nuclear matter based on chiral two-, three-, and four-nucleon interactions is presented, demonstrating a very good many-body convergence up to fourth order and exploring new chiral interactions up to N^{3}LO.

Bayesian truncation errors in chiral effective field theory: Nucleon-nucleon observables

Chiral effective field theory (EFT) predictions are necessarily truncated at some order in the EFT expansion, which induces an error that must be quantified for robust statistical comparisons to

Δ isobars and nuclear saturation

We construct a nuclear interaction in chiral effective field theory with explicit inclusion of the Δ-isobar Δ(1232) degree of freedom at all orders up to next-to-next-to-leading order (NNLO). We use

Local Nucleon-Nucleon and Three-Nucleon Interactions Within Chiral Effective Field Theory

To obtain an understanding of the structure and reactions of nuclear systems from first principles has been a long-standing goal of nuclear physics. In this respect, few- and many-body systems

Nuclear physics uncertainties in light hypernuclei

The energy levels of light hypernuclei are experimentally accessible observables that contain valuable information about the interaction between hyperons and nucleons. In this work we study

Quantifying uncertainties and correlations in the nuclear-matter equation of state

We perform statistically rigorous uncertainty quantification (UQ) for chiral effective field theory ($\chi$EFT) applied to infinite nuclear matter up to twice nuclear saturation density. The equation

Fast&rigorous predictions for $A=6$ nuclei with Bayesian posterior sampling

We make ab initio predictions for the A = 6 nuclear level scheme based on twoand three-nucleon interactions up to next-to-next-to-leading order in chiral effective field theory (χEFT). We utilize

Exploring Bayesian parameter estimation for chiral effective field theory using nucleon–nucleon phase shifts

We recently developed a Bayesian framework for parameter estimation in general effective field theories. Here we present selected results from using that framework to estimate parameters with a

The K¯N Interaction in Higher Partial Waves

The ability of the chiral higher partial waves to extend the description of the scattering data to higher energies and to account for structures in the reaction cross-sections that cannot be accommodated by theoretical models limited to the s-waves is indicated.

Global Sensitivity Analysis of Bulk Properties of an Atomic Nucleus.

A global sensitivity analysis of the binding energy and the charge radius of the nucleus ^{16}O and the most important parameters for describing nuclear saturation are identified and help prioritize efforts for uncertainty reduction of theoretical predictions.



Improved chiral nucleon-nucleon potential up to next-to-next-to-next-to-leading order

Abstract.We present improved nucleon-nucleon potentials derived in chiral effective field theory up to next-to-next-to-next-to-leading order. We argue that the nonlocal momentum-space regulator

Precision Nucleon-Nucleon Potential at Fifth Order in the Chiral Expansion.

The fifth-order corrections to nucleon-nucleon observables appear to be of a natural size, which confirms the good convergence of the chiral expansion for nuclear forces.

Power counting of contact-range currents in effective field theory.

The existence of nonperturbative physics at low energies, which is manifest in the existence of the deuteron and the ^{1}S_{0} NN virtual bound state, combined with the appearance of singular potentials in versions of nuclear EFT that incorporate chiral symmetry, modifies the renormalization-group flow of the couplings associated with contact operators that involve nucleon-nucleon pairs and external fields.
