We don't need to 'define repetition', we need to foster a culture that a) accepts repetition and b) does not accept something for a fact just because it's in a journal. Right now, (a) is not even acceptable; nobody will publish a replication study. Ofc, LHC is impossible to replicate, but the vast majority of life science studies are.
I should think this is mostly needed in life sciences. Other, more 'exact' sciences seem to not have this problem.
