Are these codes are reliable to use in scholarly work? #1

Hi, I am new to cosmoTransitions and facing problems. Is your code is reliable to use in scholarly work ? Since until now there was no issues created. Where I have to change the example file to implement a new high energy model.

Hi,

This is just an implementation of the SM potential within CosmoTransitions. It is meant to be an example of how to code up more complicated models; it has been tested to the extent that you see in the accompanying notebook. I did use a very similar set up in https://arxiv.org/abs/1504.05949 though. Note that the module was written for an older version of CT, so I am not sure if everything is still compatible; however it should be straightforward to port it to the new one.

If you want to implement a new model, you'll need to change the functions V0, bosonMassSq and fermionMassSq, which compute the tree-level potential, and the field-dependent masses of bosons and fermions.

The script also demonstrates how one could initialize the potential parameters lambda and mu from physical inputs, the Higgs mass and vev. If you don't want to do that you can just specify the potential parameters directly, and significantly simplify the initialization, since you would not need to solve RG equations anymore.
