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 …
