No: FLUKA distinguishes bettwen partcles that are produced and particles
that are transported.
All particles and resonances listed in Particle Data Group, with the
exception of those containg quarks heavier than charm, are produced.
Those which have a very short lifetime, i.e. the resonances with hadronic
decay, are decayed immediately after their production. The reason is that
even at the highest energies their path would be irrelevantly short.
In particular phi(1020) is indeed produced and has its decay list
according to measured branching ratios (dominated in this case by
Internally to the code, Produced particles and transported particles
have different numbering schemes. Only transported particle numbers
are normally accessible to the user.
