SUMMARY:Maciej Kierkla: Conformal model for gravitational waves and dark matter. A status update
DESCRIPTION:We present an updated analysis of the first-order phase transition associated with symmetry breaking in the early Universe in a classically scale-invariant model extended with a new SU(2) gauge group.\nIncluding recent developments in understanding supercooled phase transitions\, we compute all of its characteristics and significantly constrain the parameter space. We then predict gravitational-wave spectra generated during this phase transition and by computing the signal-to-noise ratio we conclude that this model is well testable (and falsifiable) with LISA. We also provide predictions for the relic dark matter abundance. It is consistent with observations in a rather narrow part of the parameter space\, as we exclude the so-called supercool dark matter scenario based on an improved description of percolation and reheating after the phase transition as well as inclusion of the running of couplings.\nFinally\, we pay special attention to renormalisation-scale dependence of the results and even though our main results are obtained with the use of renormalisation-group improved effective potential\, we also present the outcome of a fixed-scale analysis. It proves that the dependence on the scale is not only qualitative but also quantitative.\nhttps://indico.ijs.si/event/1555/
