Path from Lattice QCD to the Short-Distance Contribution to 0νββ Decay with a Light Majorana Neutrino.
The result of this work fills the gap between first-principles studies of the nn→pp(ee) amplitude from lattice QCD and those from effective field theory, and can be readily employed in the ongoing lattice-QCD studies of this process.
Toward simulating quantum field theories with controlled phonon-ion dynamics: A hybrid analog-digital approach
Quantum field theories are the cornerstones of modern physics, providing relativistic and quantum mechanical descriptions of physical systems at the most fundamental level. Simulating real-time
Ab Initio Structure Factors for Spin-Dependent Dark Matter Direct Detection.
We present converged ab initio calculations of structure factors for elastic spin-dependent WIMP scattering off all nuclei used in dark matter direct-detection searches: ^{19}F, ^{23}Na, ^{27}Al,
Digital Quantum Simulation of the Schwinger Model and Symmetry Protection with Trapped Ions
Tracking the dynamics of physical systems in real time is a prime application of quantum computers. Using a trapped-ion system with up to six qubits, we simulate the real-time dynamics of a lattice
From asymptotic freedom to $\theta$ vacua: Qubit embeddings of the O(3) nonlinear $\sigma$ model
Conventional lattice formulations of θ vacua in the 1 + 1 -dimensional O (3) nonlinear sigma model suffer from a sign problem. Here, we construct the first sign-problem-free regularization for
Neutrinoless Double-Beta Decay: A Roadmap for Matching Theory to Experiment
The observation of neutrino oscillations and hence non-zero neutrino masses provided a milestone in the search for physics beyond the Standard Model. But even though we now know that neutrinos are
Preparation of the SU(3) lattice Yang-Mills vacuum with variational quantum methods
Studying QCD and other gauge theories on quantum hardware requires the preparation of physically interesting states. The Variational Quantum Eigensolver (VQE) provides a way of performing vacuum

Determining the leading-order contact term in neutrinoless double β decay
We present a method to determine the leading-order (LO) contact term contributing to the nn → ppe − e − amplitude through the exchange of light Majorana neutrinos. Our approach is based on the


Lattice QCD determination of neutron-antineutron matrix elements with physical quark masses
Matrix elements of six-quark operators are needed to extract new physics constraints from experimental searches for neutron-antineutron oscillations. This work presents in detail the first lattice
The role of Lattice QCD in searches for violations of fundamental symmetries and signals for new physics
Abstract.This document is one of a series of white papers from the USQCD Collaboration. Here, we discuss opportunities for Lattice Quantum Chromodynamics (LQCD) in the research frontier in
Nuclear Parity Violation from Lattice QCD
The electroweak interaction at the level of quarks and gluons are well understood from precision measurements in high energy collider experiments. Relating these fundamental parameters to Hadronic
Two-neutrino double- β decay in pionless effective field theory from a Euclidean finite-volume correlation function
Two-neutrino double-beta decay of certain nuclear isotopes is one of the rarest Standard Model processes observed in nature. Its neutrinoless counterpart is an exotic lepton-number nonconserving
Heavy Physics Contributions to Neutrinoless Double Beta Decay from QCD.
Using lattice QCD, the necessary matrix elements of short-range operators, which arise due to heavy BSM mediators, that contribute to this decay via the leading order π^{-}→π^{+} exchange diagrams are computed.

We studied the single-particle potential of Λ, Σ, and Ξ hyperons in nucleonic matter starting from the fundamental theory of the strong interaction, QCD. First, we carried out a lattice QCD numerical
Statistical Angles on the Lattice QCD Signal-to-Noise Problem
The theory of quantum chromodynamics (QCD) encodes the strong interactions that bind quarks and gluons into nucleons and that bind nucleons into nuclei. Predictive control of QCD would allow nuclear
Nuclear σ terms and scalar-isoscalar WIMP-nucleus interactions from lattice QCD
It has been argued that the leading scalar-isoscalar WIMP-nucleus interactions receive parametrically enhanced contributions in the context of nuclear effective field theories. These contributions
