Can we detect a graviton ?
Pierre Van Hove (Institut de Physique Théorique, CEA)
The direct detection of gravitational waves provides an extraordinary confirmation of the general relativity. This opens a new window on our observable Universe. Shortly after having formulated the theory of general relativity, Albert Einstein said that quantum mechanism requires modifying his new theory of gravity. Today, we are still looking for experimental and observational indication of quantum gravity effects.
I will present the point of view of effective field theory approach to gravity. This approach allows computing classical general relativity effects as well as quantum gravity effects. I will explain that at large distance some quantum gravity effects are universal being independent of the high-energy description. This approach may be a route for finding signature of quantum gravity.
