Tasting the SU(5) nature of supersymmetry at the LHC
(2015-05-01)
Abstract: We elaborate on a recently found SU(5) relation confined to the up-(s)quark flavour space, that remains immune to large quantum corrections up to the TeV scale. We investigate the possibilities opened by this new ...
Supersymmetry breaking effects using the pure spinor formalism of the superstring
(Springer, 2014-06-23)
The SO(32) heterotic superstring on a Calabi-Yau manifold can spontaneously break supersymmetry at one-loop order even when it is unbroken at tree-level. It is known that calculating the supersymmetry-breaking effects in ...
Manifestly covariant actions for D=4 self-dual Yang-Mills and D=10 super-Yang-Mills
(Editrice Compositori Bologna, 1998-02-01)
Using an infinite number of fields, we construct actions for D = 4 self-dual Yang-Mills with manifest Lorentz invariance and for D = 10 super-Yang-Mills with manifest super-Poincare invariance. These actions are generalizations ...
Tinkertoys for the twisted D-series
(Springer, 2015-04-30)
We study 4D N = 2 superconformal field theories that arise from the compactification of 6D N = (2, 0) theories of type D-N on a Riemann surface, in the presence of punctures twisted by a Z(2) outer automorphism. Unlike the ...
Seiberg-Witten for Spin(n) with spinors
(Springer, 2015-08-07)
N = 2 supersymmetric Spin(n) gauge theory admits hypermultiplets in spinor representations of the gauge group, compatible with beta <= 0, for n <= 14. The theories with beta < 0 can be obtained as mass-deformations of the ...
Manifestly covariant actions for D = 4 self-dual Yang-Mills and D = 10 super-Yang-Mills
(1998-12-01)
Using an infinite number of fields, we construct actions for D = 4 self-dual Yang-Mills with manifest Lorentz invariance and for D = 10 super-Yang-Mills with manifest super-Poincaré invariance. These actions are generalizations ...

Linking natural supersymmetry to flavour physics
(2014-01-01)
With the aim of linking natural supersymmetry to flavour physics, a model is proposed based on a family symmetry G × U(1), where G is a discrete nonabelian subgroup of SU(2), with both F-term and (abelian) D-term supersymmetry ...
