The Muon Anomalous Magnetic Moment and the Pion Polarizability
Kevin T. Engel, Michael J. Ramsey-Musolf
We compute the charged pion loop contribution to the muon anomalous magnetic moment , taking into account the effect of the charged pion polarizability, . We…
Hadronic Light-by-Light and the Pion Polarizability
Kevin T. Engel, Hiren H. Patel, Michael J. Ramsey-Musolf
We compute the charged pion loop contribution to the light-by-light scattering amplitude for off-shell photons in chiral perturbation theory through next-to-leading order (NLO). We…
Solitonic Brane Inflation
Kevin T. Engel
We present a new type of brane inflation motivated by multi-kink solitonic solutions of a scalar field in five dimensions. In the thin brane limit, we analyze a non-static configur…
Trispectrum versus Bispectrum in Single-Field Inflation
Kevin T. Engel, Keith S. M. Lee, Mark B. Wise
In the standard slow-roll inflationary cosmology, quantum fluctuations in a single field, the inflaton, generate approximately Gaussian primordial density perturbations. At present…
