The report i mentioned in my message was:
Nuclear interactions in proton therapy: dose and relative biological effect distributions originating from primary and secondary particles (H Paganetti 2002).
However, I changed my physics list to

AddPhysicsList("LHEP");
   AddPhysicsList("emstandard_opt3");
  SetBuilderList1(true);
    hadronPhys.push_back( new HadronPhysicsQGSP_BERT_HP());

and i got very similar results to the Paganetti report's.
my result is:

Beam particle proton
Beam Energy(MeV) 160
Number of events 1000000
Average energy deposit (MeV) 145.8 RMS(MeV) 28.42
Average number of steps 651.8
Average number of gamma 0.5715
Average number of e- 1.744
Average number of e+ 0.0113
Average number of neutrons 0.8475
Average number of protons 1.818
Average number of antiprotons 0
Average number of pi+ & pi- 1e-06
Average number of pi0 0
Average number of kaons 0
Average number of muons 1e-06
Average number of deuterons 0.06982
Average number of tritons 0.03413
Average number of he3 0.002867
Average number of alpha 0.1024
Average number of ions 0.8093

As u can see, they all match Paganetti results except number of alpha!!!
I read somewhere that if i want to include optical photon in hadronic package i should work with LBE physics list.
Is this true?
and how i can include the LBE?
