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.
