title: "Figure 26b" of "Measurements of $\mu\mu$ pairs from open heavy flavor and Drell-Yan in $p+p$ collisions at $\sqrt{s}=200$ GeV"

description: The differential yield $dN/dp_{T}$ of like-sign muon pairs from bottom with mass 3.5-10.0 GeV/$c^2$ in the ideal muon arm acceptance, as a function of the pair transverse momentum. Statistical (stat.) and types B and C systematic errors (sys. B & sys. C) are all $10^{-9}\times$[$c$/GeV].
description: PHENIX reports differential cross sections of $\mu\mu$ pairs from semileptonic heavy-flavor decays and the Drell-Yan production mechanism measured in $p+p$ collisions at $\sqrt{s}$ = 200 GeV at forward and backward rapidity (1.2 &lt; |$\eta$| &lt; 2.2). The $\mu\mu$ pairs from $c\bar{c}$, $b\bar{b}$, and Drell-Yan are separated using a template fit to unlike- and like-sign muon pair spectra in mass and $p_{T}$ . The azimuthal opening angle correlation between the muons from $c\bar{c}$ and $b\bar{b}$ decays and the pair-$p_{T}$ distributions are compared to distributions generated using pythia and powheg models, which both include next-to-leading order processes. The measured distributions for pairs from $c\bar{c}$ are consistent with pythia calculations. The $c\bar{c}$ data presents narrower azimuthal correlations and softer $p_{T}$ distributions compared to distributions generated from powheg. The $b\bar{b}$ data are well described by both models. The extrapolated total cross section for bottom production is 3.75$\pm$0.24(stat)$\pm$$^{0.35}_{0.50}$(syst)$\pm$0.45(global)[$\mu$b], which is consistent with previous measurements at the Relativistic Heavy Ion Collider in the same system at the same collision energy, and is approximately a factor of two higher than the central value calculated with theoretical models. The measured Drell-Yan cross section is in good agreement with next-to-leading-order quantum-chromodynamics calculations.

title: "Tight efficiency" of "Search for short- and long-lived axion-like particles in $H\rightarrow a a \rightarrow 4\gamma$ decays with the ATLAS experiment at the LHC"

description: Identification efficiency for isolated photons that pass the tight photon ID requirements in dependence of the opening angle in $\Delta R$ of both decay photons of the axion and the decay radius of the originating axion from the primary vertex for axions with masses between 100 MeV and 300 MeV. All four axion decay photons on MC truth level are required to fulfil $|\eta|&lt;2.5$ and $p_T&gt;5$ GeV. Only a mild dependency on the decay radius can be seen, since the distance between the two photons is small and hence the combined decay signature in the calorimeter still points to the primary vertex.

title: "Central values" of "Tests of light-lepton universality in angular asymmetries of $B^0 \to D^{*-} \ell \nu$ decays"

description: Observed values of all angular asymmetry variables.
description: We present the first comprehensive tests of the universality of the light leptons in the angular distributions of semileptonic $B^0$-meson decays to charged spin-1 charmed mesons. We measure five angular-asymmetry observables as functions of the decay recoil that are sensitive to lepton-universality-violating contributions. We use events where one neutral $B$ is fully reconstructed in $\Upsilon\left(4S\right)\to{}B\overline{B}$ decays in data corresponding to $189~\mathrm{fb}^{-1}$ integrated luminosity from electron-positron collisions collected with the Belle II detector. We find no significant deviation from the standard model expectations.

title: "Table 1" of "Measurement of $ZZ$ production cross-sections in the four-lepton final state in $pp$ collisions at $\sqrt{s}=13.6$ TeV with the ATLAS experiment"

description: The measured differential cross-sections compared to the predictions in the $m_{4\ell}$ bins
description: This paper reports cross-section measurements of $ZZ$ production in $pp$ collisions at $\sqrt{s}= 13.6$ TeV at the Large Hadron Collider. The data were collected by the ATLAS detector in 2022, and correspond to an integrated luminosity of 29 fb$^{-1}$. Events in the $ZZ\rightarrow4\ell$ ($\ell = e$, $\mu$) final states are selected and used to measure the inclusive and differential cross-sections in a fiducial region defined close to the analysis selections. The inclusive cross-section is further extrapolated to the total phase space with a requirement of $66 &lt; m_Z &lt; 116$ GeV for both $Z$ bosons, yielding $16.8 \pm 1.1$ pb. The results are well described by the Standard Model predictions.
