Trigger Level Analysis
QCD distribution is expected to be smooth.
Several NP models could lead to a localized excess.
-The high dijets mass resonance search is well covered.
- The low dijets mass resonance search is limited due to finite trigger
bandwidth, which imposes high prescales for high rate processes.

Dijet Angular Analysis
Complementary for to mass resonance search, to account
for wide resonances or high tail,
Gain higher sensitivity from the angular data.
Opportunity to distinguish between different models.
