Modelindependent radiative symmetry breaking and gravitational waves
Abstract
Models where symmetries are predominantly broken (and masses are then generated) through radiative corrections typically produce strong firstorder phase transitions with a period of supercooling, when the temperature dropped by several orders of magnitude. Here it is shown that a modelindependent description of these phenomena and the consequent production of potentially observable gravitational waves is possible in terms of few parameters (which are computable once the model is specified) if enough supercooling occurred. It is explicitly found how large the supercooling should be in terms of those parameters, in order for the modelindependent description to be valid. It is also explained how to systematically improve the accuracy of such description by computing higherorder corrections in an expansion in powers of a small quantity, which is a function of the abovementioned parameters. Furthermore, the corresponding gravitational wave spectrum is compared with the existing experimental results from the latest observing run of LIGO and VIRGO and the expected sensitivities of future gravitational wave experiments to find regions of the parameter space that are either ruled out or can lead to a future detection.
