The Polarised Photon Sum Rule at the Linear Collider and High Luminosity B Factories
G. M. Shore
The sum rule for the first moment of the polarised (virtual) photon structure function is revisited in the light of proposals for future colliders. The…
Refining the Proof of Planar Equivalence
A. Armoni, M. Shifman, G. Veneziano
We outline a full non-perturbative proof of planar (large-N) equivalence between bosonic correlators in a theory with Majorana fermions in the adjoint representation and one with D…
Twistor Space Structure of the Box Coefficients of N=1 One-loop Amplitudes
Steven J. Bidder, N. E. J. Bjerrum-Bohr, David C. Dunbar +1
We examine the coefficients of the box functions in N=1 supersymmetric one-loop amplitudes. We present the box coefficients for all six point N=1 amplitudes and certain all exa…
Lattice Study of Anisotropic QED-3
Simon Hands, Iorwerth Owain Thomas
We present results from a Monte Carlo simulation of non-compact lattice QED in 3 dimensions on a lattice in which an explicit anisotropy between and hopping terms ha…
On the Coulomb Branch of a Marginal Deformation of N=4 SUSY Yang-Mills
Nick Dorey, Timothy J. Hollowood
We determine the exact vacuum structure of a marginal deformation of N=4 SUSY Yang-Mills with gauge group U(N). The Coulomb branch of the theory consists of several sub-branches wh…
The structure of weak coalgebra-Galois extensions
Tomasz Brzezinski, Ryan B. Turner, Adam P. Wrightson
Weak coalgebra-Galois extensions are studied. A notion of an invertible weak entwining structure is introduced. It is proven that, within an invertible weak entwining structure, th…
