Hello Kirill,

Your Physics List is similar to the default which is using parameterized model (GHEISHA, derived from G3). There is a bug - you instantiate 2 AtRest processes - one obsolere G4AntiProtonAnnihilationAtRest and recommanded one G4QCaptureAtRest. I would remove the first one.

To have better anti_proton physics you likely need to use other G4 models. I would let you communicate with original authors of FTF base models, QGS base models, CHIPS models and Bertini. They should clarify if any of above can be used now and at what energy.
