I am a M.Sc. graduated and I have applied for a few PhD programs abroad. A few months ago, we submitted our paper (which was about my thesis results) to a journal and also uploaded it to a pre-print server. Then, I mentioned the paper in my CV with the status "submitted to journal X". In my Skype meeting with a potential advisor from a university abroad, I mentioned the fact that we submitted the paper and we have not notified about the result yet. Then, I sent the link of the paper on pre-print server to him according to his request. Today, I got informed by the journal's editor that our paper got rejected from Journal X, so now I don't know if I need to tell this fact to the potential advisor in our next Skype meeting or through other mediums like email? In general, I guess he will not ask about the status of our paper and if he asks about this, definitely I would tell the right but I don't know should I tell him about the rejection even if he does not ask about it? Actually the journal quality is very high and we believe that we can publish our papers in another good journal elsewhere, However the professor is from a different field and he may not know how hard it is to publish in journal X. Thus, I think that this news unfairly ruin my admission chance.
