Anomaly Mediation and Cosmology
A. Basboll, M. Hindmarsh, D. R. T. Jones
We consider an extension of the MSSM wherein anomaly mediation is the source of supersymmetry breaking, and the tachyonic slepton problem is solved by a gauged U(1) symmetry, which…
SUSY Flat Directions -- to get a VEV or not?
Anders Basboll
We investigate the potential of SUSY flat directions (FDs). Large FD vacuum expectation values (VEVs) can delay thermalisation and solve the gravitino problem - if FDs decay pertur…
MSSM superpotential to 6th order - normalised and with no superfluous couplings
Anders Basboll
We expand the superpotential of MSSM to 6th order. This is the order at which all flat directions can be lifted. All 5179 couplings are independent ie. the superpotential cannot…
A complete and minimal catalogue of MSSM gauge invariant monomials
Anders Basboll
We present a complete and minimal catalogue of MSSM gauge invariant monomials. That is, the catalogue of Gherghetta, Kolda and Martin is elaborated to include generational structur…
Non-Perturbative Flat Direction Decay
Anders Basboll, David Maybury, Francesco Riva +1
We argue that supersymmetric flat direction vacuum expectation values can decay non-perturbatively via preheating. Considering a toy U(1) gauge theory, we explicitly calculate the…
Decay of heavy Majorana neutrinos using the full Boltzmann equation including its implications for leptogenesis
Anders Basboll, Steen Hannestad
We have studied the two-body production and decay of a heavy, right-handed neutrino to two light states using the full Boltzmann equation instead of the usual integrated Boltzmann…
