Hi all,

In 2011 CDF experiment at Tevatron announced that they had reported W+2jets signal excess for 2 jets
mass range around Mjj ~ 150 GeV but D0 experiment didn't see this signal anomaly using the same criteria.

So have any one an idea or recent reference how this discrepancy had explained ? or did the LHC exp.
gave any other results about this W+2jets excess ..

Bests,
Safinaz

CDF have published a recent update on this with twice more data and different modelling for multijet events and jet calibration. They find the data to be consistent with the standard model
