SUMMARY

The forum discussion centers on the discrepancy between the W+2jets signal reported by the CDF experiment at Tevatron in 2011 and the lack of similar findings by the D0 experiment. The CDF reported an excess in the 2 jets mass range around Mjj ~ 150 GeV, while D0 did not observe this anomaly. A recent update from CDF, utilizing twice the amount of data and improved modeling for multijet events and jet calibration, indicates that their findings are now consistent with the standard model.

PREREQUISITES
  • Understanding of W+2jets signal in particle physics
  • Familiarity with the CDF and D0 experiments at Tevatron
  • Knowledge of multijet event modeling techniques
  • Jet calibration methods in high-energy physics
NEXT STEPS
  • Research the latest findings from the CDF experiment on W+2jets signals
  • Explore the methodologies used in multijet event modeling
  • Study jet calibration techniques in high-energy physics
  • Investigate how the LHC experiments have addressed W+2jets anomalies
USEFUL FOR

Particle physicists, researchers in high-energy physics, and anyone interested in the discrepancies of experimental results at Tevatron and their implications for the standard model.

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 anyone 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
