Abstract

The direct detection of gravitational waves will yield important consequences to Physics and Astrophysics. The SCHENBERG detector, built with FAPESP s financial support, is now in a testing phase. It is expected to be collecting scientific data in the next year. In principle, a detector such as SCHENBERG allows, among other results, the discrimination among different theories proposed to explain gravitation. Investigations are going on for several years on this subject and recently they have included theories with massive gravitons. This research project aims to develop a procedure that will allow the identification of the metric theory of gravitation from SCHENBERG s detected signal. (AU)
