Abstract

The interaction of high energy cosmic rays with gravitational antennas produces spurious signals in the gravitational wave detectors. We will study the flows of the cosmic rays in Sao Paulo and its energy and angular distributions. We will utilize the term-acoustic model for evaluate the intensity of those signs in the gravitational antenna Mario Schenberg. This study it will be used in the veto of cosmic rays of the gravitational antenna Schenberg.
