Buchdahl bound, photon ring, ISCO and radial acceleration in Einstein-æther theory

Posted by dbos Cambridge, This Week: Astrophysics

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Yi-Hsiung Hsu, Anthony Lasenby, Will Barker, Amel Durakovic, Michael Hobson | Summary: Spherically symmetric Einstein-{ae}ther (E{AE}) theory with a Maxwell-like kinetic term is revisited. We consider a general choice of the metric and the ae{}ther field, finding that:~(i) there is a gauge freedom allowing one always to […]

LHC EFT WG Note: Basis for Anomalous Quartic Gauge Couplings

Posted by dbos This Week: Astrophysics, Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Gauthier Durieux, Grant N. Remmen, Nicholas L. Rodd, O. J. P. Éboli, M. C. Gonzalez-Garcia | Summary: In this note, we give a definitive basis for the dimension-eight operators leading to quartic — but no cubic — interactions among electroweak gauge bosons. These are often called anomalous […]
