One has no reasons to require that also thedescription of processes be invariant (ref. (5b)). In particular, two different inertial observers might judge the total electric charge involved in a physical reaction as having two different values (this may be just the case for charged tachyons): the main point is thatevery observer must see the total electric charge to be conserved in that reaction.
Differently from what asserted in ref. (1b), a tachyon cannot decay in a set of particles and/or antiparticles and/or photons, for trivial kinematical reasons. Further (different) mistakes are contained in ref. (9): see ref. (1b, 10).
