Is there a difference between Experience Design(XD) and UX design

Going through various sources, I am getting that UX designing is a perspective limited to designing services and products as per audience and Experience design holds more artistic temperament for implementing imagination without a specific audience.I mean if a person is more inclined to just express his imagination without much of rules and guidelines for any "corporate" or "professional" sense and also is not limited to just painting his imagination and can play around with objects and environment that even serves an experience but not intended to give a specific result. Is there any help from UX design field or am I right when i think that the above stated is a separate field known as XD or am I not clear about the nature of UX and confusing it with XD which are different names of same class.
