# Lagrangian

[Category:Model](/Category:Model "wikilink") For a realistic model, in particular a SUSY model, the Lagrangian is generally very lengthy. Therefore, SARAH splits it in different parts in order to speed up some calculations. This splitting might be also helpful for analyzing the structure of interactions involving different kinds of fields. SARAH saves the different parts of the Lagrangian for the different eigenstates in the following variables:

- `LagSV[$EIGENSTATES]`: Parts with scalars and vector bosons (= kinetic terms for scalars)

- `LagFFV[$EIGENSTATES]`: Parts with fermions and vector bosons (= kinetic terms of scalars)
