title: "Figure 2e" of "Suppression pattern of neutral pions at high transverse momentum in Au+Au collisions at sqrt(s_NN) = 200 GeV and constraints on medium transport coefficients"

description: Nuclear modification factor ($R_{AA}$) for $\pi^0$s. The bin range is not an uncertainty in the x-axis because the actual uncertainty by having the finite bin width is corrected for by the bin-shift correction. These bins were constructed using the corrected finite values as centers.
description: For Au+Au collisions at 200 GeV, we measure neutral pion production with good statistics for transverse momentum, $p_T$, up to 20 GeV/$c$. A fivefold suppression is found, which is essentially constant for 5 &lt; $p_T$ &lt; 20 GeV/$c$. Experimental uncertainties are small enough to constrain any model-dependent parameterization for the transport coefficient of the medium, e.g. $&lt;\bar{q}&gt;$ in the parton quenching model. The spectral shape is similar for all collision classes, and the suppression does not saturate in Au+Au collisions; instead, it increases proportional to the number of participating nucleons, as $N_{part}^{2/3}$.

title: "Table 1" of "Search for a new heavy scalar particle decaying into a Higgs boson and a new scalar singlet in final states with one or two light leptons and a pair of $\tau$-leptons with the ATLAS detector"

description: Observed and expected 95% CL upper limits are shown for $\sigma(pp\to X\to SH)$ obtained from $WW1\ell2\tau_{\mathrm{had}}$, $WW2\ell2\tau_{\mathrm{had}}$, $ZZ2\ell2\tau_{\mathrm{had}}$, and their combination, as a function of combined $m_{S}$ and $m_{X}$ masses ($m_{S}$+$m_{X}/25$) in GeV.
description: Search for a new heavy scalar particle decaying into a Higgs boson and a new scalar singlet in final states with one or two light leptons and a pair of $\tau$-leptons with the ATLAS detector.

A search for a new heavy scalar particle $X$ decaying into a Standard Model (SM) Higgs boson and a new singlet scalar particle $S$ is presented. The search uses a proton-proton ($pp$) collision dataset with an integrated luminosity of 140 fb$^{-1}$ recorded at a center-of-mass energy of $\sqrt{s} = 13$ TeV with the ATLAS detector at the Large Hadron Collider. The explored $X$ masses range from 500 to 1500 \GeV\,with the corresponding $S$ mass varying from 200 to 500 GeV. The search selects events with two hadronically decaying $\tau$-lepton candidates from $H\to \tau^+\tau^-$ decays and one or two light leptons ($\ell=e,\,\mu$) from $S\to VV$ ($V = W,\,Z$) decays. A multivariate discriminant based on event kinematics is used to separate signal from background. No excess events were observed beyond the expected SM background and 95\% confidence level upper limits between 72 fb and 542 fb are derived on the cross-section for $\sigma(pp\to X\to SH)$ assuming the SM-Higgs boson-like $S\to VV$ decay. Upper limits on the visible cross-section for $\sigma(pp\to X\to SH \to WW\tau\tau)$ and $\sigma(pp\to X\to SH \to ZZ\tau\tau)$ are also set in the ranges 3--26 fb and 6--33 fb, respectively.

title: "Table 4" of "Search for a new heavy scalar particle decaying into a Higgs boson and a new scalar singlet in final states with one or two light leptons and a pair of $\tau$-leptons with the ATLAS detector"

description: Event yields after a background-only fit and data in the three signal regions. All the backgrounds except the fake $\tau_{\mathrm{had}}$ are estimated using the real $\tau_{\mathrm{had}}$ contributions from MC. The fake $\tau_{\mathrm{had}}$ background contribution is data-driven. The top-quark, $V$+jets, and small backgrounds are included in "Others". The total uncertainties include both systematic and statistical. In the $WW1\ell2\tau_{\mathrm{had}}$ channel, the smaller uncertainty in the total background than the fake $\tau_{\mathrm{had}}$ is due to the anticorrelations between the nuisance parameters of the fake $\tau_{\mathrm{had}}$ and diboson backgrounds obtained in the fit.

description: Summary of observed and expected 95\% CL upper limits on the production cross-section of $\sigma(pp\to X\to SH)$ in fb in the combination of $WW$+$ZZ$, and in the $WW$ and $ZZ$ individual channels.

title: "Figure 5" of "Transverse momentum dependence of J/psi polarization at midrapidity in p+p collisions at sqrt(s)=200 GeV"

description: $J/\psi$ yield times dielectron branching ratio ($B$) after detector acceptance and efficiency corrections for the real data with $A$ = 28.7 $\pm$ 1.0 nb/GeV/$c$, $b$ = 3.41 $\pm$ 0.21 GeV/$c$, and $n$ = 4.6 $\pm$ 0.4.
description: We report the measurement of the transverse momentum dependence of inclusive $J/\psi$ polarization in $p$+$p$ collisions at $\sqrt{s}$ = 200 GeV performed by the PHENIX Experiment at RHIC. The polarization is studied in the helicity, Gottfried-Jackson, and Collins-Soper frames for $p_T$ &lt; 5 GeV/$c$ and $|y|$ &lt; 0.35. The J/psi polarization in the helicity and Gottfried-Jackson frames is consistent with zero for all transverse momenta, with a slight (1.8 sigma) trend towards longitudinal polarization for transverse momenta above 2 GeV/$c$. No conclusion is allowed due to the limited acceptance in the Collins-Soper frame and the uncertainties of the current data. The results are compared to observations for other collision systems and center of mass energies and to different quarkonia production models.

title: "Figure 1" of "Measurement of transverse single-spin asymmetries for mid-rapidity production of neutral pions and charged hadrons in polarized p + p collisions at s**(1/2) = 200-GeV."

description: Invariant cross section vs. $p_T$ for the production of charged hadrons at mid-rapidity.
description: The transverse single-spin asymmetries of neutral pions and non-identified charged hadrons have been measured at mid-rapidity in polarized proton-proton collisions at $\sqrt{s}$ = 200 GeV. The data cover a transverse momentum $(p_T)$ range 0.5-5.0 GeV/$c$ for charged hadrons and 1.0-5.0 GeV/$c$ for neutral pions, at a Feynman-$x$ $(x_F)$ value of approximately zero. The asymmetries seen in this previously unexplored kinematic region are consistent with zero within statistical errors of a few percent. In addition, the inclusive charged hadron cross section at mid-rapidity from 0.5 &lt; $p_T$ &lt; 7.0 GeV/$c$ is presented and compared to NLO pQCD calculations. Successful description of the unpolarized cross section above ~2 GeV/$c$ using NLO pQCD suggests that pQCD is applicable in the interpretation of the asymmetry results in the relevant kinematic range.
