Conformal unification in a quiver theory and gravitational waves
The detection of a stochastic background of gravitational waves can reveal details about first-order phase transitions (FOPTs) at a time of 10−13s of the early universe. We specifically discuss quiver-type GUTs which avoid both proton decay and a desert hypothesis. A quiver based on SU(3)12 which br...

Zusammenfassung: | The detection of a stochastic background of gravitational waves can reveal details about first-order phase transitions (FOPTs) at a time of 10−13s of the early universe. We specifically discuss quiver-type GUTs which avoid both proton decay and a desert hypothesis. A quiver based on SU(3)12 which breaks at a E=4000GeV to trinification SU(3)3 has a much larger (g⁎=1,272) number of effective massless degrees of freedom than the Standard Model. Assuming a FOPT for this model, we investigate the strain sensitivity of typical of this model for a wide range of FOPT parameters. |
