Updates on the unknown

CDF (one of the collider experiments at Fermilab) has just presented another update on their April paper on the invariant mass distribution of jet pairs produced in association with a W boson. In the latter one they discussed an excess in the 120-160 GeV/c^2 mass range with a significance of 3.2 sigma. They do not dare to give an exact number but claim to be closer to 5 sigma now!?

Unfortunately, though announced several times, the D0 collaboration has not published any similar analysis yet…

Also the result is not backed by all members of the collaboration …
so it remains exciting and CDF still owes us a good explanation …
