Some new implications of the anomalous baryon current in the Standard Model
Richard J. Hill
Phenomenological implications of the anomalous baryon current in the Standard Model are discussed, in particular neutrino-photon interactions at finite baryon density. A pedagogica…
Topological physics in the standard model and beyond
Richard J. Hill
Topological interactions are an essential ingredient for building consistent low-energy theories of fermions, gauge fields and Nambu-Goldstone bosons in the absence of explicit UV…
Anomaly mediated neutrino-photon interactions at finite baryon density
Jeffrey A. Harvey, Christopher T. Hill, Richard J. Hill
We propose new physical processes based on the axial vector anomaly and described by the Wess-Zumino-Witten term that couples the photon, Z-boson, and the omega-meson. The interact…
Topological Physics of Little Higgs Bosons
Christopher T. Hill, Richard J. Hill
Topological interactions will generally occur in composite Higgs or Little Higgs theories, extra-dimensional gauge theories in which A_5 plays the role of a Higgs boson, and amongs…
Symmetry relations for heavy-to-light meson form factors at large recoil
Richard J. Hill
The description of large-recoil heavy-to-light meson form factors is reviewed in the framework of soft-collinear effective theory. At leading power in the heavy quark expansion, th…
