In some cases a model might be implemented in different bases, such as (super-)CKM or with diagonal Yukawas which may be managed in the same directory. Similary it is convenient to store models that belong to a certain category (e.g. all SplitSUSY low-energy EFTs) within one directory.
To do so, the following directory structure is supported:
where each directory contains a model .m file as well as a parameter.m and particles.m
The models are started using:
e.g. Start["SM","CKM"] starts the Standard Model with the CKM basis.
The maximum depth of sub-models is one.
Custom Model Directory
A custom model directory can be set in the file SARAH.config
