Two-nucleon scattering in multiple partial waves
Amy Nicholson, Evan Berkowitz, Enrico Rinaldi +5
We determine scattering phase shifts for S,P,D, and F partial wave channels in two-nucleon systems using lattice QCD methods. We use a generalization of Luscher's finite volume met…
Nuclear Parity Violation from Lattice QCD
Thorsten Kurth, Evan Berkowitz, Enrico Rinaldi +4
The electroweak interaction at the level of quarks and gluons are well understood from precision measurements in high energy collider experiments. Relating these fundamental parame…
Lattice QCD and Axion Cosmology
Evan Berkowitz
The Strong CP Problem can be resolved by introducing an additional global symmetry known as Peccei-Quinn symmetry. Once PQ symmetry is broken the associated particle, the QCD axion…
Two-Nucleon Higher Partial-Wave Scattering from Lattice QCD
Evan Berkowitz, Thorsten Kurth, Amy Nicholson +5
We present a determination of nucleon-nucleon scattering phase shifts for l >= 0. The S, P, D and F phase shifts for both the spin-triplet and spin-singlet channels are computed wi…
Lattice QCD input for axion cosmology
Evan Berkowitz, Michael I. Buchoff, Enrico Rinaldi
One intriguing BSM particle is the QCD axion, which could simultaneously provide a solution to the Strong CP problem and account for some, if not all, of the dark matter density in…
Direct Detection of Stealth Dark Matter through Electromagnetic Polarizability
Thomas Appelquist, Evan Berkowitz, Richard C. Brower +15
We calculate the spin-independent scattering cross section for direct detection that results from the electromagnetic polarizability of a composite scalar baryon dark matter candid…
