Abstract:

New trace anomalies appear in the presence of

exactly marginal parameters. They can be

thought of as sigma models in the space of

theories. We show that these anomalies lead to

surprising consequences for certain super

symmetric theories. One can prove that the

space of theories has trivial Kahler class. One

can further prove that the sphere partition

function has a universal normalization given in

terms of the metric in theory space. This allows

to compute the exact metric in theory space in

certain super symmetric theories. We discuss

some explicit examples such as Seiberg-Witten

theory.
