I'm a PhD student in theoretical Physics. There will be an online conference in one subject I'm very interested in and in which I want to start doing research. I have studied a few papers on the subject but I'm still a beginner. In particular I don't know what can be done in the field and I'm in hopes that attending the conference will help with that.
In that case I think it could be a good idea to prepare myself for this conference studying some relevant papers. Is it OK to send an email to the organizer asking for some references which would be a good idea to study before attending?
