Few months ago, I had submitted a manuscript to the prestigious journal, Physical Review Letters (PRL). The manuscript had undergone two rounds of review at PRL where it was reviewed by a total of five reviewers. Three reviewers had recommended for its publication in the PRL, while the fourth reviewer considered the manuscript to be more suitable for another journal from the American Physical Society family - Physical Review E. Unfortunately, the fifth reviewer had rejected the manuscript without citing any reason. In fact, the editor of the PRL had even agreed that the manuscript warrants publication but following their rule that allows a manuscript to be reviewed for a maximum of only two times, PRL chose not to take the reviewing/publishing of the manuscript any further.
Is it okay to mention the above information in the cover letter of the next journal that I am targeting for my manuscript? Could the editor get a negative vibe from it? Could it backfire?
