TL;DR: In this article, the polarization parameter measurements for the reaction π−p→π0n at 22 momenta between 617 and 2267 MeV/c were presented, in agreement with those of previous measurements and in qualitative agreement with predictions of phase shift analyses.

TL;DR: In this article, the results of a search for the pair production of photon-jets in the ATLAS detector at the Large Hadron Collider are reported, and the results are interpreted in the context of a model containing a new, high-mass scalar particle with narrow width, X, that decays into pairs of photonjets via new, light particles, a upper limits are placed on the cross section times the product of branching ratios σ×B(X→aa)×B (a→γγ)2 for 200 GeV.

TL;DR: In this article, the properties of high-mass multijet events produced at the Fermilab proton-antiproton collider are compared with leading order QCD matrix element predictions, QCD parton shower Monte Carlo predictions, and the predictions from a model in which events are distributed uniformly over the available multibody phase space.

TL;DR: In this paper, the authors analyzed the energy density distribution in harronic final states as a function of their total transverse energy measured in the segmented central calorimeter of the UA2 detector.

TL;DR: Aaltonen, T., Amerio, S., Amidei, D., Anastassov, A, Annovi, A., Antos, J.,... Zucchelli, S. as discussed by the authors measured the center-of-momentum energy of 1.96 TeV.
