Applicability of the PAI Model to Kaons

Dear experts,

The Geant4 documentation [1] does not explicitly specify the projectile particles for which the PAI model is applicable. In the paper describing the PAI model implementation [2], it is stated that:

It allows us to calculate the ionisation energy loss distribution produced by relativistic charged particles in very thin layers of any material consisting of elements with Z = 1-100.

Additionally, a presentation at the 2015 collaboration meeting [3] lists e+/-, mu+/-, pi+/-, protons, and gammas as applicable particle types.

How can I confirm if the PAI model, once enabled in a region, also applies to other particle types, such as kaons?

Thank you for your time.

Best,
Alvaro
