Event Details

In this work, we investigate the gravitational wave aspect of the Nnaturalness models. They have been previously well studied in the context of higgs hierarchy problem. We find that Nnaturalness by itself cannot explain the recent observation of stochastic GW background observed recently by NANOGrav. However a large chunk of Nnaturalness parameter space can be probed by future PTA experiments as well as planned (LISA, BBO) and proposed (-Ares) space based gravitaional wave observatories.
