What’s the deal with the X(3872)? Why are we still finding new mesons at low mass? There’s still new physics to be found at lower energies!
Apologies to CDF for not mentioning them by name, they saw a very clear signal for the X(3872) as well!
Some excellent talks on the X(3872) can be found in the Charm 2010 conference: http://indico.ihep.ac.cn/conferenceOtherViews.py?view=standard&confId=1452
I’m still playing catch-up! More to come tomorrow.
