Lectures on W - Gravity , W - Geometry and W - Strings ⋆
Classical W-gravities and the corresponding quantum theories are reviewed. W-gravities are higher-spin gauge theories in two dimensions whose gauge algebras are W-algebras. The geometrical structure of classical W-gravity is investigated, leading to surprising connections with self-dual and special geometry. The anomalies that arise in quantum W-gravity are discussed, with particular attention ...
متن کاملEffects of TeV Scale Gravity on e+e− → W+W−
We study the process e+e− → W+W− to probe low-scale gravity at high energy linear colliders. A characteristic signature of extra-dimensions models is the forward-backward asymmetry due to the interference of spin2 graviton and spin-1 SM gauge boson exchange terms, even when rightpolarised electron beam is used. Our analysis shows that larger than 5% asymmetry is possible at a linear collider wi...
متن کاملAnomaly-free W-gravity Theories
We give a review of some recent developments in the quantisation of W-gravity theories. In particular, we discuss the construction of anomaly-free W ∞ and W 3 gravities.
متن کاملChiral Rings in Topological (W-)Gravity
We review the superconformal properties of 2d matter coupled to gravity, and extensions thereof. Focusing on topological strings, we recall how the superconformal structure helps to provide a direct link between Liouville theory coupled to matter, and matrix models. We also construct an infinite class of new theories based on W -gravity.
