title: "Figure 18" of "Nonprompt direct-photon production in Au$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV"

description: $T_{eff}$ vs charged particle multiplicity
description: BNL-RHIC. The measurement of the direct photon spectrum from Au$+$Au collisions at $\sqrt{s_{NN}}$ = 200 GeV is presented by the PHENIX collaboration using the external photon conversion technique for 0\%--93\% central collisions in a transverse momentum ($p_T$) range of 0.8--10 GeV/$c$. An excess of direct photons, above prompt photon production from hard scattering processes, is observed for $p_T&lt; 6$ GeV/$c$. nonprompt direct photons are measured by subtracting the prompt component, which is estimated as $N_{coll}$-scaled direct photons from p+p collisions at 200 GeV, from the direct photon spectrum. Results are obtained for $0.8&lt;$p_T$&lt;6.0$ GeV/$c$ and suggest that the spectrum has an increasing inverse slope from about 0.2 GeV/$c$ to around 0.4 GeV/$c$ with increasing $p_T$. This indicates a possible sensitivity of the measurement to photons from earlier stages of the evolution of the collision. In addition, like the direct photon production, the $p_T$-integrated nonprompt direct photon yields also follow a power law scaling behavior as a function of collision system size. The exponent, $\alpha$, for the nonprompt component is found to be consistent with 1.1 with no apparent $p_T$ dependence.

description: Comparison of the number of events observed in 2016 data in the STA-STA dimuon category with the expected number of background events, in representative $m_{\mu \mu}$ intervals. The black points with crosses show the number of observed events; the green and yellow components of the stacked histograms represent the estimated numbers of DY and QCD events, respectively. The last bin includes events in the overflow. The uncertainties in the total expected background (shaded area) are statistical only. Signal contributions expected from simulated $H \rightarrow Z_D Z_D$ with $m_{Z_D}$ of 20 and 50 GeV are shown in red and blue, respectively. Their yields are set to the corresponding combined median expected exclusion limits at 95% CL, scaled up as indicated in the legend to improve visibility. The legends also include the total number of observed events as well as the number of expected background events obtained inclusively, by applying the background evaluation method to the events in all $m_{\mu \mu}$ intervals combined.
