First Leptophobic Dark Matter Search from the Coherent-CAPTAIN-Mills Liquid Argon Detector.

We report the first results of a search for leptophobic dark matter (DM) from the Coherent-CAPTAIN-Mills (CCM) liquid argon (LAr) detector. An engineering run with 120 photomultiplier tubes (PMTs) and 17.9×10^{20} protons on target (POT) was performed in fall 2019 to study the characteristics of the CCM detector.

A search is reported for a narrow vector resonance decaying to quark-antiquark pairs in proton-proton collisions at sqrt[s]=13 TeV, collected with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.7 fb^{-1}.

Article Synopsis
- A study was conducted on proton-proton collisions at 8 TeV to search for narrow resonances decaying into dijet final states, using data from the CMS detector with a total integrated luminosity of 18.8 fb^{-1}.
- The researchers utilized a novel data scouting technique to efficiently collect large amounts of data by streamlining the event information, which enhanced the detection of low-mass resonances at a higher rate.
- The analysis resulted in no evidence for narrow resonances in the dijet mass distribution, and upper limits on resonance cross sections and couplings, specifically for a leptophobic resonance Z_{B}^{'}, were established, surpassing previous experimental results for masses between 500 and 800 GeV.
Semivisible Jets: Dark Matter Undercover at the LHC.

Dark matter may be a composite particle that is accessible via a weakly coupled portal. If these hidden-sector states are produced at the Large Hadron Collider (LHC), they would undergo a QCD-like shower. This would result in a spray of stable invisible dark matter along with unstable states that decay back to the standard model.

Article Synopsis
- * The study used a data sample with an integrated luminosity of 2.05 fb at a proton-proton collision energy of 7 TeV, but found no evidence of resonance.
- * Limits on the production of narrow bosons were established, with 95% credibility level limits showing excluded mass ranges from 500 GeV to 1300 GeV, specifically ruling out a leptophobic topcolor boson below 880 GeV.
