Charges which are not pheno-constrained and do not regenerate dangerous couplings with Yukawas #

i. Overview #

WARNING: This file can take a long time to compute.

In this module, given a configuration of the sections in codimension one fiber CodimensionOneConfig, we find the multiset of all -valued charges which have values allowed by the configuration, permit a top Yukawa coupling, are not phenomenologically constrained, and do not regenerate dangerous couplings with one insertion of a Yukawa coupling.

The multiset of charge spectrum is called viableCharges. The main proof that viableCharges contains all such charges is using completeness_of_isPhenoClosedQ5_isPhenoClosedQ10. Note this proof relies on us stating viableCharges and then verifying that it has the required properties.

To make our lives easier, we first construct a multiset of charge spectrum called viableCompletions which contains all completions of charges which minimally allow the top Yukawa, which are not phenomenologically constrained, and do not regenerate dangerous couplings. Again the proof that viableCompletions has these properties is done by first stating viableCompletions and then verifying that it has the required properties, primarily using ContainsPhenoCompletionsOfMinimallyAllows.

We also define viableChargesAdditional which are the multiset of charge spectrum which are in viableCharges but not in viableCompletions. This helps split some of the proofs.

Note that this file is slow to run, any improvements to the speed of this file will be very welcome. In particular working out a way to restrict by anomaly cancellation.

    All charges, for a given CodimensionOneConfig, I, which permit a top Yukawa coupling, are not phenomenologically constrained, and do not regenerate dangerous couplings with one insertion of a Yukawa coupling.

      We now show that adding a Q5 or a Q10 charge to an element of viableCharges I leads to a charge which is either not phenomenologically constrained, or does not regenerate dangerous couplings, or is already in viableCharges I.

      Inserting a q5 charge into an element of viableCharges I either

      1. produces another element of viableCharges I, or
      2. produce a charge which is phenomenologically constrained or regenerates dangerous couplings with the Yukawas.

      Inserting a q10 charge into an element of viableCharges I either
