If the cosmological constant Λ can not be neglected, we will show in this short report, that graviton should have a rest mass mg = √ 2Λ = √ 2Λh̄c−1 different from zero.

We recently published an analysis of the coincidences of the Explorer and Nau-tilus gravitational wave detectors in the year 2001 [1]. This has drawn attention and criticism by dr. S. Finn [2]. We discuss here why we do not agree with his arguments and conclusions, taking the opportunity to make some further considerations on our data.

The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation laws, and get a scale relation relating the energy-momentum and spin tensors. Such scale relation is an intrinsic property for matter fields in Lyra background.
