Nuclear Electromagnetic Currents in Chiral Effective Field Theory
… nuclear electromagnetic currents are derived in chiral effective field theory retaining pions and nucleons as explicit degrees of freedom. The calculation of the potential is carried out up to next-to-next-to leading order (N<sup>2</sup>LO), while the currents include up to N<sup>3</sup>LO …

Chiral effective field theory beyond the power-counting regime.
Chiral effective field theory complements numerical simulations of quantum chromodynamics on a spacetime lattice. It provides a model-independent formalism for connecting lattice simulation results at finite volume, and at a variety of quark masses, to the physical region. Knowledge of the …

Studies of Two-Nucleon Interactions and Few-Body Electromagnetic Structure in Chiral Effective Field Theory
… nucleon-nucleon potential is constructed in chiral effective field theory (χEFT) retaining pions, nucleons and Δ-isobars as explicit degrees of freedom. The calculation of the potential is carried out by including one-and two-pion-exchange contributions up to next-to-next-to-leading order …

Nuclear Chiral Axial Currents and Applications to Few-Nucleon Systems
… parts. The first part discusses basic aspects of chiral effective field theory and the formalism, based on time ordered perturbation theory, used to to derive the nuclear potentials and currents from the chiral Lagrangians. The second part deals with the actual derivation, up to one loop, of the …

Advances in ab initio approaches to nuclear structure, reaction and nucleonic dynamics
<p>We calculate effective Hamiltonians and effective electroweak operators with the Okubo-Lee-Suzuki formalism for two-nucleon systems. Working within a harmonic oscillator basis, first without and then with a confining harmonic oscillator trap, we demonstrate the effects of renormalization on …

The search for dark matter in xenon: Innovative calibration strategies and novel search channels
… large-scale shell-model calculations with chiral effective field theory WIMP-nucleon currents, finding that the inelastic channel is comparable to or can dominate the elastic channel for momentum transfers around 150 MeV. I calculate the inelastic recoil spectra in the standard halo model, …
