title: "Figure 7 Theory 2" of "Neutral pion cross section and spin asymmetries at intermediate pseudorapidity in polarized proton collisions at $\sqrt{s} = 200$ GeV"

description: The ALL results (blue markers) are presented with the DSSV prediction and the GRSV prediction using the best fit to polarized DIS ($\Delta$ g = std) and the maximum and minimum allowed values for gluon polarization.
description: The differential cross section and spin asymmetries for neutral pions produced within the intermediate pseudorapidity range 0.8 &lt; $\eta$ &lt; 2.0 in polarized proton-proton collisions at $sqrt{s}$ = 200 GeV are presented. Neutral pions were detected using the endcap electromagnetic calorimeter in the STAR detector at RHIC. The cross section was measured over a transverse momentum range of 5 &lt; $p_{T}$ &lt; 16 GeV/c and is found to be within the scale uncertainty of a next-to-leading order perturbative QCD calculation. The longitudinal double-spin asymmetry, $A_{LL}$, is measured in the same pseudorapidity range. This quantity is sensitive to the gluonic contribution to the proton spin, $\Delta$g(x), at low Bjorken-x (down to x $\approx$ 0.01), where it is less constrained by measurements at central pseudorapidity. The measured $A_{LL}$ is consistent with model predictions. The parity-violating asymmetry, $A_{L}$, is also measured and found to be consistent with zero. The transverse single-spin asymmetry, $A_{N}$, is measured within a previously unexplored kinematic range in Feynman-x and $p_{T}$. Such measurements may aid our understanding of the on-set and kinematic dependence of the large asymmetries observed at more forward pseudorapidity ($\eta \approx 3$) and their underlying mechanisms. The $A_{N}$ results presented are consistent with a twist-3 model prediction of a small asymmetry within the present kinematic range.

title: "Table 1" of "Search for supersymmetry in events with four or more charged leptons in $139\,\textrm{fb}^{-1}$ of $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector"

description: The $E_{\mathrm{T}}^{\mathrm{miss}}$ distribution in SR0-ZZ$^{\mathrm{loose}}$ and SR0-ZZ$^{\mathrm{tight}}$ for events passing the signal region requirements except the $E_{\mathrm{T}}^{\mathrm{miss}}$ requirement. Distributions for data, the estimated SM backgrounds after the background-only fit, and an example SUSY scenario are shown. "Other" is the sum of the $tWZ$, $t\bar{t}WW$, $t\bar{t} ZZ$, $t\bar{t} WH$, $t\bar{t} HH$, $t\bar{t} tW$, and $t\bar{t}t\bar{t}$ backgrounds. The last bin captures the overflow events. The lower panel shows the ratio of the observed data to the expected SM background yield in each bin. Both the statistical and systematic uncertainties in the SM background are included in the shaded band. The red arrows indicate the $E_{\mathrm{T}}^{\mathrm{miss}}$ selections in the signal regions.
description: A search for supersymmetry in events with four or more charged leptons (electrons, muons and $\tau$-leptons) is presented. The analysis uses a data sample corresponding to $139\,\mbox{fb\(^{-1}\)}$ of proton-proton collisions delivered by the Large Hadron Collider at $\sqrt{s}=13\,\text{Te\kern -0.1em V}$ and recorded by the ATLAS detector. Four-lepton signal regions with up to two hadronically decaying $\tau$-leptons are designed to target several supersymmetric models, while a general five-lepton signal region targets any new physics phenomena leading to a final state with five charged leptons. Data yields are consistent with Standard Model expectations and results are used to set upper limits on contributions from processes beyond the Standard Model. Exclusion limits are set at the 95\% confidence level in simplified models of general gauge-mediated supersymmetry, excluding higgsino masses up to $540\,\text{Ge\kern -0.1em V}$. In $R$-parity-violating simplified models with decays of the lightest supersymmetric particle to charged leptons, lower limits of $1.6\,\text{Te\kern -0.1em V}$, $1.2\,\text{Te\kern -0.1em V}$, and $2.5\,\text{Te\kern -0.1em V}$ are placed on wino, slepton and gluino masses, respectively.
