Search for dijet resonances using events with three jets in proton-proton collisions at s=13TeV

Search for new phenomena using jets at CMS

“…Figure 4: Upper limits at 95% CL on the universal quark coupling g q ', as a function of resonance mass, for a narrow vector resonance that only couples to quarks. The observed limits (solid curve), expected limits (dashed curve) and their variation (shaded bands) are shown [7].…”

“…The main background originates from QCD multijet events (t-channel production). This analysis [7] is using a special data-taking technique called data scouting, which consists of saving only the calorimeter-based jets reconstructed by the software trigger system in CMS, allowing the analysis of much larger rate of data. In order to increase sensitivity to even lower resonance masses with respect to the trigger requirements, this search selects events with at least three jets in the final state.…”

Enhancing scalar productions with leptoquarks at the LHC

“…It may be possible to put a bound on σ ϕ ðM ϕ Þ from the dijet resonance searches. For example, the one performed by the CMS Collaboration at the 13 TeV LHC [80] indicates that σ ϕ × BRðϕ → ggÞ has to be less than about 1 pb for M ϕ ¼ 1 TeV and about 20 pb for M ϕ ¼ 600 GeV. Similarly, in the quark mode, σ ϕ ×BRðϕ → dd þ ss þ bbÞ is less than about 1 pb for M ϕ ¼ 1 TeV and about 5 pb for M ϕ ¼ 600 GeV.…”

Search for dijet resonances in events with an isolated charged lepton using $$ \sqrt{s} $$ = 13 TeV proton-proton collision data collected by the ATLAS detector

“…Studies of this kind were among the first published using early data from the ATLAS [1][2][3][4] and CMS [5][6][7] experiments at the Large Hadron Collider (LHC) at CERN, when operations at high energy first began. Later results used new datasets as the LHC increased the collision energy, from 7 TeV to 8 TeV during Run 1 [8][9][10], and then to 13 TeV for Run 2 [11][12][13][14][15][16][17][18]. Typically, these searches initially focused on resonances with high dijet invariant masses, m jj , e.g.…”
