I recently submitted my first ever conference abstract, and then discovered after submission deadline that in one of my citations I forgot to add "et al." even though the cited paper has multiple authors. So now only the primary author is cited in the text, even though all authors are, of course, included in the reference list. Stupid mistake, I know, and I'm really kicking myself about it. Especially because the mistake was simply a brain fart - I do know how to cite properly.
My question is - if the abstract is otherwise consistent and of high quality, may the abstract still be accepted despite the citation mistake? All other citations in the abstract are correct. There is just this one slip-up which I'm now afraid may cause my abstract to be rejected even though I am convinced the actual research is of sufficient quality for acceptance.
