Maths HEP Lunchtime Seminars: "On d=4,5,6 Vacua with 8 Supercharges"
10 July 2002 00:00 in CM221
"In this talk we are going to show how all maximally supersymmetric vacua of N=2, d=4,5,6 Supergravity theories (Hpp-waves and Ads x S spacetimes) are related through dimensional reduction, preserving, contrary to what is usually believed, all the unbroken supersymmetries. This yields to a unified picture of all of them. In particular, in d=5, the known maximally supersymmetric AdS_2 xS^3 and AdS_3 x S^2 spacetimes will be shown to belong to the same family of vacua in parameter space due to the underlying four-dimensional electric-magnetic duality. Finally, a possible generalization to eleven-dimenisonal Supergravity will be briefly discussed."
