TL;DR: In this paper, the authors measured the four-momentum transfer range of the proton-antiproton elastic scattering at a center-of-mass energy of 540 GeV in the range 0.05 t s.19 GeV 2.

TL;DR: In this article, the upsilon(2) was measured in the pseudorapidity range |eta| ≤ 2.5 with the event plane method. But the up-silon 2 transformed to the rest frame of one of the colliding nuclei is compared to the lower-energy RHIC data.

TL;DR: In this paper, the authors measured the polarization of τ-leptons as a function of the production polar angle using the following 1-prong τ decay modes: τ − → e − v e v τ, τ− →π − (K − )v τ, τ − − →ϱ − v τ and τ −→a 1 − vτ, and obtained for the ratio vector to axial-vector weak neutral couplings for electrons gVe/gAe=0.0791± 0.0099(stat)±0.

TL;DR: In this article, additional jet activity in dijet events is measured using pp collisions at ATLAS at a centre-of-mass energy of 7 TeV, for jets reconstructed using the anti-kt algorithm with radius parameter R = 0.6.
