title: "Table 20" 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 resonant signal sample, with $m_{X}$ = 300 GeV, 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.

title: Alien woman with scarab beetle on forehead II

description: Alien-looking female head and neck, bald head, long pointed ear, scarab beetle on elongated forehead with green, yellow, and brown background. Notes left by OT: When he first came in the shop was diagnosed as schizophrenic, paranoid and his paintings reflected the diagnosis. His work was extremely fragmented with lips, part of a torso, and the ever present, all seeing eye. The eye persisted as part of his artwork until the paranoia dimished. After several months of painting a scarab appeared on the forehead of a face which he was obsessed with. He refused to tell me who she was. Whoever she was, the face was firmly implanted in his memory. Even as he seemed to improve and the syptoms of his paranoia dimished the image persisted. I had seen the scarab appear in other mental patients' painting but never knew "why a scarab?" As he progressed the scarab was replaced by a simple forehead dot. He eventually painted a relaxed, composed, beautiful protrait of the woman in question.
