How to pull back my paper from conference? My first year undergraduate teammate submitted our paper to two conferences yesterday. I am afraid that this can lead to self plagiarism. Help me. How do I withdraw our paper? What should I say to conference organizers? This is a deeply concerning problem. Please help.
It depends on which conference you have submitted. There are several interfaces (the most popular one being easychair), and each of them has an option to withdraw paper before notification of acceptance (or rejection).

Just log into the website and click withdraw paper button.
