Jul 19, 2015 at 13:15 | comment | added | ACuriousMind♦ | "For example, all gauge symmetries must be unbroken due to unitarity of theory." To avoid confusing with the SSB by of $\mathrm{SU}(2)$-gauge symmetry by the Higgs, it should be stressed that this is at the level of the non-perturbative Lagrangian. | |
Jul 19, 2015 at 11:17 | comment | added | romanovzky | I just want to point out that your explanation of why the SM is anomaly free is not correct and based on speculation. The SM gauge group is also a subgroup of SU(5) and E6, for example, which do not entail only anomaly free theories. The SO(10) embedding is incomplete -- SM rank is 4, SO(10) is 5, SM has 12 gauge bosons, SO(10) has 20, SM matter does not fill entire SO(10) irreps, etc). SO(10) GUT cannot be used to justify SM anomaly free as it is still a speculative assumption, although its anomaly free nature is one of the many reasons why it is appealing. | |
