I am being accused of academic dishonesty on a problem for a class this year. I have already accepted an offer to a Ph.D program and if I am convicted, there will be no mark on the final transcript I send them, and the effects are probably going to be nonexistent on my actual grade. Should I be concerned that this will turn up, and is it likely I will have to disclose this later?
Edit (some more information that may be relevant):
This has no way of connecting to the professors who wrote my recommendation. My concern in case of conviction is mainly the extent to which I may have to graduate schools, and whether or not my existing statement that I have not been convicted (submitted prior to all this) will be checked (in the case of a conviction, it may appear that I lied).
The alleged offense is itself minor (as far as these things go) and based on resemblance with something online. Not that I expect this to have an impact on how it is externally viewed.
