Half-BPS quotients in M-theory: ADE with a twist
Paul de Medeiros, José Figueroa-O'Farrill, Sunil Gadhia +1
We classify Freund-Rubin backgrounds of eleven-dimensional supergravity of the form AdS_4 x X^7 which are at least half BPS; equivalently, smooth quotients of the round 7-sphere by…
On Half-BPS States of the ABJM Theory
M. M. Sheikh-Jabbari, Joan Simon
We analyze SU(2) invariant half-BPS states of the 3d \cN=8 or \cN=6 SCFT within the radial quantization of the ABJM theory, the theory proposed to describe N M2-branes in the R^3x…
Gauge fixing, BRS invariance and Ward identities for randomly stirred flows
Arjun Berera, David Hochberg
The Galilean invariance of the Navier-Stokes equation is shown to be akin to a global gauge symmetry familiar from quantum field theory. This symmetry leads to a multiple counting…
Amplitudes and Spinor-Helicity in Six Dimensions
Clifford Cheung, Donal O'Connell
The spinor-helicity formalism has become an invaluable tool for understanding the S-matrix of massless particles in four dimensions. In this paper we construct a spinor-helicity fo…
The homogeneity conjecture for supergravity backgrounds
José Miguel Figueroa-O'Farrill
These notes record three lectures given at the workshop "Higher symmetries in Physics", held at the Universidad Complutense de Madrid in November 2008. In them we explain how to co…
Mass corrections in string theory and lattice field theory
Luigi Del Debbio, Eoin Kerrane, Rodolfo Russo
Kaluza-Klein compactifications of higher dimensional Yang-Mills theories contain a number of four dimensional scalars corresponding to the internal components of the gauge field. W…
