T-parity violation by anomalies
Little Higgs theories often rely on an internal parity ('T-parity') to suppress nonstandard electroweak effects or to provide a dark matter candidate. We show that such a symmetry is generally broken…
Standard Model anatomy of WIMP dark matter direct detection II: QCD analysis and hadronic matrix elements
Models of weakly interacting massive particles (WIMPs) specified at the electroweak scale are systematically matched to effective theories at hadronic scales where WIMP-nucleus scattering observables…
Extraction of the proton radius from electron-proton scattering data
- Gabriel Lee, J. Arrington, R. Hill
- Physics
- 6 May 2015
We perform a new analysis of electron-proton scattering data to determine the proton electric and magnetic radii, enforcing model-independent constraints from form factor analyticity. A wideranging…
Deuterium target data for precision neutrino-nucleus cross sections

- 9 March 2016
Amplitudes derived from scattering data on elementary targets are basic inputs to neutrino-nucleus cross section predictions. A prominent example is the isovector axial nucleon form factor, FA(q2),…
Nucleon axial radius and muonic hydrogen—a new analysis and review

- 28 August 2017
Muonic hydrogen can provide a precise and independent value which may be compared with other determinations, such as ongoing lattice gauge theory calculations, and the importance of an improved [Formula: see text] determination for phenomenology is illustrated by considering the impact on critical neutrino-nucleus cross sections at neutrini oscillation experiments.
Model independent determination of the axial mass parameter in quasielastic neutrino-nucleon scattering
- Bhubanjyoti Bhattacharya, R. Hill, G. Paz

- 1 August 2011
Quasielastic neutrino-nucleon scattering is a basic signal process for neutrino oscillation studies. At accelerator energies, the corresponding cross section is subject to significant uncertainty due…
Sudakov resummation for subleading SCET currents and heavy-to-light form factors
- R. Hill, T. Becher, Seung J. Lee, M. Neubert
- Physics
- 23 April 2004
The hard-scattering contributions to heavy-to-light form factors at large recoil are studied systematically in soft-collinear effective theory (SCET). Large logarithms arising from multiple energy…
Lorentz invariance in heavy particle effective theories
- Johannes Heinonen, R. Hill, M. Solon
- Physics
- 2 August 2012
Employing induced representations of the Lorentz group (Wigner's little group construction), formalism for constructing heavy particle effective Lagrangians is developed, and Lagrangian constraints…
