Interesting article, and I believe I have a better translation: "Today, my mom died." It sounds better than just "mom" and seems to express the right level of closeness.
OTOH I think it's often appropriate to keep "mamma" in Italian movies and texts because it carries a huge amount of connotations, which "maman" doesn't.
