Robustness and Violations of a Scalar Equivalence Principle
Speaker(s): Lam Hui
Abstract: Modified gravity theories under consideration typically reduce to a scalar-tensor form in the appropriate limits. I will discuss in what sense a universal scalar coupling is stable against quantum corrections, when the scalar equivalence principle is violated, how to look for such violations, and the connection with cosmic acceleration.
