I think your MSc would qualify you for a PhD admission. While you do not need to have published papers in order to be awarded a PhD, it's good if you can publish papers before your submission and viva. That way your work has already been peer reviewed and consequently, it makes it harder for examiners to fail you! I have heard it said that a PhD thesis should contain sufficient work to produce 3 full papers, but I have no official reference for that statement. Good luck with your applications :o)
