Low Energy Precision Test of Supersymmetry
M. J. Ramsey-Musolf, S. Su
Supersymmetry (SUSY) remains one of the leading candidates for physics beyond the Standard Model, and the search for SUSY will be a central focus of future collider experiments. Co…
Minimal Extension of the Standard Model Scalar Sector
Donal O'Connell, Michael J. Ramsey-Musolf, Mark B. Wise
The minimal extension of the scalar sector of the standard model contains an additional real scalar field with no gauge quantum numbers. Such a field does not couple to the quarks…
Model Independent Naturalness Bounds on Magnetic Moments of Majorana Neutrinos
Mikhail Gorchtein, Nicole F. Bell, Michael J. Ramsey-Musolf +2
We analyze the implications of neutrino masses for the magnitude of neutrino magnetic moments. By considering electroweak radiative corrections to the neutrino mass, we derive mode…
Constraints on Muon Decay Parameters from Neutrino Mass
Rebecca J. Erwin, Jennifer Kile, Michael J. Ramsey-Musolf +1
We derive model-independent constraints on chirality-changing terms in the muon decay Lagrangian using limits on neutrino mass. We consider all dimension-six operators invariant un…
Nuclei as Laboratories: Nuclear Tests of Fundamental Symmetries
Michael J. Ramsey-Musolf
The prospect of a rare isosotope accelerator facility opens up possibilities for a new generation of nuclear tests of fundamental symmetries. In this talk, I survey the current lan…
Supersymmetric Contributions to Weak Decay Correlation Coefficients
Stefano Profumo, Michael J. Ramsey-Musolf, Sean Tulin
We study supersymmetric contributions to correlation coefficients that characterize the spectral shape and angular distribution for polarized muon- and beta-decays. In the minimal…
Model Independent Bounds on Magnetic Moments of Majorana Neutrinos
Nicole F. Bell, Mikhail Gorchtein, Michael J. Ramsey-Musolf +2
We analyze the implications of neutrino masses for the magnitude of neutrino magnetic moments. By considering electroweak radiative corrections to the neutrino mass, we derive mode…
Yukawa and Tri-scalar Processes in Electroweak Baryogenesis
Vincenzo Cirigliano, Christopher Lee, Michael J. Ramsey-Musolf +1
We derive the contributions to the quantum transport equations for electroweak baryogenesis due to decays and inverse decays induced by tri-scalar and Yukawa interactions. In the M…
Probing the Fundamental Symmetries of the Early Universe: The Low Energy Frontier
M. J. Ramsey-Musolf
Searching for the fundamental symmetries that characterize the particle physics of the early universe lies at the forefront of particle physics, nuclear physics, and cosmology. In…
Baryogenesis, Electric Dipole Moments and Dark Matter in the MSSM
Vincenzo Cirigliano, Stefano Profumo, Michael J. Ramsey-Musolf
We study the implications for electroweak baryogenesis (EWB) within the minimal supersymmetric Standard Model (MSSM) of present and future searches for the permanent electric dipol…
Neutrino Mass Implications for Muon Decay Parameters
Rebecca J. Erwin, Jennifer Kile, Michael J. Ramsey-Musolf +1
We use the scale of neutrino mass to derive model-independent naturalness constraints on possible contributions to muon decay Michel parameters from new physics above the electrowe…
Schiff Theorem and the Electric Dipole Moments of Hydrogen-Like Atoms
C. -P. Liu, W. C. Haxton, M. J. Ramsey-Musolf +2
The Schiff theorem is revisited in this work and the residual - and -odd electron--nucleus interaction, after the shielding takes effect, is completely specified. An applicat…
Magnetic Moments of Dirac Neutrinos
Nicole F. Bell, V. Cirigliano, M. J. Ramsey-Musolf +2
The existence of a neutrino magnetic moment implies contributions to the neutrino mass via radiative corrections. We derive model-independent "naturalness" upper bounds on the magn…
