title: "vertex_efficiency_R_84_111_mm" of "Search for long-lived, massive particles in events with displaced vertices and multiple jets in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector"

description: Reinterpretation Material: Vertex-level Efficiency for R [84, 111] mm
description: A search for long-lived particles decaying into hadrons ispresented. The analysis uses 139 fb$^{-1}$ of $pp$ collision datacollected at $\sqrt{s} = 13$ TeV by the ATLAS detector at the LHCusing events that contain multiple energetic jets and a displacedvertex. The search employs dedicated reconstruction techniques thatsignificantly increase the sensitivity to long-lived particlesdecaying in the ATLAS inner detector. Background estimates forStandard Model processes and instrumental effects are extracted fromdata. The observed event yields are compatible with those expectedfrom background processes. The results are used to set limits at95% confidence level on model-independent cross sections forprocesses beyond the Standard Model, and on scenarios withpair-production of supersymmetric particles with long-livedelectroweakinos that decay via a small $R$-parity-violatingcoupling. The pair-production of electroweakinos with masses below1.5 TeV are excluded for mean proper lifetimes in the range from0.03~ns to 1~ns. When produced in the decay of m(gluino)=2.4 TeVgluinos, electroweakinos with m(neutralino)=1.5 TeV are excludedwith lifetimes in the range of 0.02~ns to 4~ns.

title: "Table 1" of "Double helicity asymmetry in inclusive mid-rapidity pi0 production for polarized p + p collisions at s**(1/2) = 200-GeV."

description: Double spin asymmetry for the raw signal ($\pi^0 + BG$), for the background ($BG$) and for $\pi^0$ background corrected; single spin asymmetry for $\pi^0$ background corrected; for the four $p_T$ bins.
description: We present a measurement of the double longitudinal spin asymmetry in inclusive $\pi^0$ production in polarized proton-proton collisions at $\sqrt{s}$ = 200 GeV. The data were taken at the Relativistic Heavy Ion Collider with average beam polarizations of 27%. The measurements are the first of a porgram to study the longitudinal spin structure of the proton, using strongly interacting probes, at collider energies. The asymmetry is presented for transverse momenta 1-5 GeV/$c$ at mid-rapidity, where next-to-leading order perturbative quantum chromodynamic (NLO pQCD) calculations well describe the unpolarized cross section. The observed asymmetry is small and is compared with a NLO pQCD calculation with a range of polarized gluon distributions.

description: Distributions of the reconstructed m<sub>HH</sub> in data (shown by the black points), the estimated background (shown by the yellow histograms) in the VBF signal region with |Δη<sub>HH</sub>| &lt; 1.5.
The hatching shows the total uncertainty of the background estimate. 
The distribution of the expected background is obtained using the best-fit values of the nuisance parameters in the fit to the data with the background-only hypothesis.
Distributions for three choices of couplings are shown: the SM, κ<sub>λ</sub>= 6, and κ<sub>2V</sub> = 0 (with all other couplings set to their SM values in the last two models), scaled so as to be visible on the plot. 
The lower panels show the ratio of the observed data yield to the predicted background in each bin.
Events in the overflow bins are counted in the yields of the final bins.
In the HEPData entry, the raw value per histogram bin is provided, while in the published paper the values in the histogram are scaled by the bin width.
