title: "Table 25" of "Search for dark photons in rare $Z$ boson decays with the ATLAS detector"

description: Observed and expected upper limits at 95% CL on $\alpha_{D}\epsilon^{2}$ as a function of $m_{A'}$ at dark Higgs boson mass of 20 GeV
description: A search for events with a dark photon produced in association with a dark Higgs boson via rare decays of the Standard Model $Z$ boson is presented, using $139~fb^{-1}$ of $\sqrt{s} = 13$ TeV proton--proton collision data recorded by the ATLAS detector at the Large Hadron Collider. The dark Higgs boson decays into a pair of dark photons, and at least two of the three dark photons must each decay into a pair of electrons or muons, resulting in at least two same-flavor opposite-charge lepton pairs in the final state. The data are found to be consistent with the background prediction, and upper limits are set on the dark photon's coupling to the dark Higgs boson times the kinetic mixing between the Standard Model photon and the dark photon, $\alpha_{D}\epsilon^2$, in the dark photon mass range of $[5, 40]$ GeV except for the $\Upsilon$ mass window $[8.8, 11.1]$ GeV. This search explores new parameter space not previously excluded by other experiments.

title: "Table 1" of "First measurement of prompt and non-prompt ${\rm D^{*+}}$ vector meson spin alignment in pp collisions at $\sqrt{s} = 13$ TeV"

description: The spin density matrix element ($\rho_{00}$) for prompt and non-prompt $\mathrm{D^{*\pm}}$ mesons as a function of $p_\mathrm{T}$ in pp collisions at $\sqrt{s}=13$ TeV. Measurements are carried out with respect to the helicity axis at $| y | &lt;0.8$
description: This letter reports the first measurement of spin alignment, with respect to the helicity axis, for $\mathrm{D}^{*+}$ vector mesons and their charge conjugates from charm-quark hadronisation (prompt) and from beauty-meson decays (non-prompt) in hadron collisions. The measurements were performed at midrapidity ($|y|&lt;0.8$) as a function of transverse momentum ($p_\mathrm{T}$) in proton–proton (pp) collisions collected by ALICE at the centre-of-mass energy $\sqrt{s}=13$ TeV.The diagonal spin density matrix element $\rho_{00}$ of $\mathrm{D}^{*+}$ mesons was measured from the angular distribution of the $\mathrm{D}^{*+}\rightarrow\mathrm{D^0}\pi^+$ decay products, in the $\mathrm{D}^{*+}$ rest frame, with respect to the $\mathrm{D}^{*+}$ momentum direction in the pp centre of mass frame.The $\rho_{00}$~value for prompt $\mathrm{D}^{*+}$ mesons is consistent with $1/3$, which implies no spin alignment. However, for non-prompt $\mathrm{D}^{*+}$ mesons an evidence of $\rho_{00}$ larger than $1/3$ is found. The measured value of the spin density element is $\rho_{00}=0.455\pm0.022(\text{stat})\pm0.035(\text{syst})$ in the $5
