title: "Supplemental Figure 1 Ratio_p40pbar40, 200 GeV" of "Measurement of the sixth-order cumulant of net-proton multiplicity distributions in Au+Au collisions at $\sqrt{s_{NN}}=$ 27, 54.4, and 200 GeV at RHIC"

description: Distributions of reconstructed protons (black circles) from embedding simulations in 200 GeV Au+Au collisions at 0-2.5% centrality. Red lines are fits with the binomial distribution, and green dotted lines represent the fit with the beta-binomial distributions using α that gives the minimal chi2/ndf. Each panel shows the result from the given combinations of embedded protons and antiprotons. The ratio of fits to the embedding data is shown for each panel.
description: According to the first principle Lattice QCD calculations, the transition from quark-gluon plasma to hadronic matter is a smooth crossover in the region $\mu_{B}$ ≤ $T_{c}$. As a result, higher-order cumulants and their ratios are predicted to be negative, $C_{6}/C_{2}$ &lt; 0, for example. In this paper, we report the first measurement of the midrapidity net-proton $C_{6}/C_{2}$ from 27, 54.4 and 200 GeV Au+Au collisions at RHIC. The dependence on collision centrality and kinematic acceptance in ($p_{T}$ , $y$) are analyzed. While for 54.4 GeV collisions, most of C6/C2 values are larger or equal to zero, it is observed that for 27 and 200 GeV collisions, the values of C6/C2 progressively become negative from peripheral to central collisions. Transport model calculations without critical dynamics predict values around zero. These observations seem in favor of a smooth crossover in the high energy nuclear collisions at RHIC.

title: "Supplemental Figure 2, 200 GeV" of "Measurement of the sixth-order cumulant of net-proton multiplicity distributions in Au+Au collisions at $\sqrt{s_{NN}}=$ 27, 54.4, and 200 GeV at RHIC"

description: Cumulants and their ratios up to the sixth order corrected for non-binomial efficiencies for 200 GeV Au+Au collisions at 0-5% centrality. The CBWC is applied for 2.5% centrality bin width. Results from the conventional efficiency correction are shown as black filled circles, results from the unfolding with the binomial detector response are shown as black open circles, and results from beta-binomial detector response with $\alpha+\sigma$, $\alpha$ and $\alpha-\sigma$ are shown in green triangles, red squares and blue triangles, respectively. C5, C6, C2/C1, C5/C1 and C6/C2 are scaled by constant shown in each column.

title: Despairing man

description: Male (?) head and shoulders outlined in black, dark brown, and green; green, yellow, and orange shirt against a dark blue and orange background. Note left on reverse side by OT: 3. Notes left by OT: Fourteen year old 'F' had crawled under the fence at the Boys School in Paso Robles, California. Always the day before he was to be released to his home in Los Angeles. The staff at the Boys School were confused because the pattern was always the same. He was told that he was going home and within the next few hours he would crawl under the fence and steal a staff car from the parking lot. Staff cars only filled their cars before they left the facility and were habitualy left parked with a small amount of gas so the boy did not get very far. They sent him to the State Hospital because he had escaped and that was against the law. He certainly didn't belong in a hospital with 800 sex psychopaths. I kept him with me. Six hours in the OT clinic was a partial solution for providing a safe environment. He had no art training but he was handy with a brush and colors. ..... Picture #3. a man, same sense of darkness and despair. .... I packed the pictures of the family and sent them to his social worker. He was released to a foster family in Northern California.

title: "Table 19" of "Search for Higgs boson pair production in the two bottom quarks plus two photons final state in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Cutflow for nonresonant di-Higgs ggF signal sample, yields are normalized to 139 $fb^{-1}$.
description: CERN-LHC, ATLAS.
Limits on pair production of Higgs bosons in the final state with two bottom quarks plus two photons.
The search is based on 139 $fb^{-1}$ of pp collisions at $\sqrt{s}$ = 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider.
Data include exactly two b-tagged jets with a 77% working point and two well-identified isolated photons.
The search is sensitive to both resonant and nonresonant production of Higgs boson pairs.
Both the nonresonant and resonant searches employ multivariate analysis techniques to select events. Events are selected if they satisfy a common set of preselection requirements; then they are required to fulfill different requirements for the nonresonant and the resonant search. These further requirements are based on the BDT scores shown in tables 1 to 6. 
$m^{*}_{b\bar{b}\gamma\gamma} = m_{b\bar{b}\gamma\gamma} - m_{b\bar{b}} - m_{\gamma\gamma} + 250$ GeV is used to implement selection criteria for both the nonresonant and resonant analyses. 

Preselection:
- there are at least two photons passing the tight and isolated object selection criteria;
- the di-photon invariant mass, built with the two leading photons, satisfies 105 GeV &lt; $m_{\gamma\gamma}$ &lt; 160 GeV;
- the leading (sub-leading) photon $p_{T}$ is larger than 35% (25%) of the mass of the di-photon system;
- there are exactly two b-tagged jets at 77% working point;
- no electrons or muons are present;
- fewer than six central (|$\eta$|&lt; 2.5) jets are required, to help rejecting $t\bar{t}H$ events where the top quarks decay hadronically.


Non-resonant selection:
Following the preselection, events are divided into two regions using the value of $m^{*}_{b\bar{b}\gamma\gamma}$. High mass region with $m^{*}_{b\bar{b}\gamma\gamma} &gt; 350$ GeV targets the SM signal, while low mass region with $m^{*}_{b\bar{b}\gamma\gamma} &lt; 350$ GeV targets BSM signals. In each mass region, a dedicated BDT is trained using XGBoost, and two categories are defined based on the BDT score. Events with a BDT score below 0.881 in the low mass region or below 0.857 in the high mass region are discarded.

Resonant selection:
Using the TMVA toolkit, two BDTs are trained to better separate the signal from backgrounds of different nature (the ${\gamma\gamma}$ plus the ${t\bar{t}\gamma\gamma}$ backgrounds and the single Higgs boson background, where ZH and ${t\bar{t}H}$ production modes are the dominant resonant backgrounds). The combined BDT score of an event ($BDT_{tot}$) is obtained by combining the two BDT scores in quadrature. Only events passing a minimum requirement on the value of the $BDT_{tot}$ are considered in the analysis. Events with a BDT score below 0.85 for $m_{X}$ = 300 GeV or below 0.75 for $m_{X}$ = 500 GeV are discarded. The BDT thresholds for other $m_{X}$ points are listed in Table 31.
