title: "Cutflow One HNL Majorana" of "Search for heavy neutral leptons in decays of $W$ bosons using a dilepton displaced vertex in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector"

description: Cutflow for six simulated signal channels showing the weighted number of expected events based on the single-flavour mixing model in the Majorana limit. Each column uses the generated signal sample with the mass hypothesis $m_N = 10$ GeV and proper decay length $c\tau_N = 10$ mm.
description: A search for a long-lived, heavy neutral lepton ($N$) in 139/fb of $\sqrt{s} = 13$ TeV $pp$ collision data collected by the ATLAS detector at the Large Hadron Collider is reported. 
The $N$ is produced via $W \rightarrow N \mu$ or $W \rightarrow N e$ and decays into two charged leptons and a neutrino, forming a displaced vertex.
The $N$ mass is reconstructed and used for background estimation.
No signal is observed, and limits are set on the squared mixing parameters of the $N$ with the left-handed neutrino states for the $N$ mass range $3$ GeV $&lt; m_N &lt; 15$ GeV. 
For the first time, limits are given for both single-flavor and multiflavor mixing scenarios motivated by neutrino flavor oscillation results for both the normal and inverted neutrino-mass hierarchies.

title: "Figure 17 (right)" of "Measurement of the production cross section for Z + b jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Distributions of the cross section ratios as a function of the leading b jet absolute pseudorapidity
description: The measurements of the cross section of the \PZ boson, decaying to dielectrons or dimuons, in association with at least one bottom quark jet are performed with proton-proton collision data at $\sqrt{s}=$ 13\TeV. The data sample corresponds to an integrated luminosity of 137.1\fbinv, collected by the CMS experiment at the LHC. The integrated cross sections of \PZ~$+\geq$~1~\cPqb~jet\xspace and \PZ~$+\geq$~2~\cPqb~jets\xspace are reported for the electron, muon, and combined channels with full Run 2 data. The measured integrated cross sections are 6.52 $\pm$ 0.04 (stat) $\pm$ 0.40 (syst) $\pm$ 0.14 (theo) pb for \PZ~$+\geq$~1~\cPqb~jet\xspace and 0.65 $\pm$ 0.03 (stat) $\pm$ 0.07 (syst) $\pm$ 0.02 (theo) pb for \PZ~$+\geq$~2~\cPqb~jets\xspace. The differential cross section distributions are measured as a function of various kinematic observables that are useful for precision tests of the perturbative quantum chromodynamics predictions. The ratios of integrated and differential cross sections of \PZ~$+\geq$~2~\cPqb~jets\xspace and \PZ~$+\geq$~1~\cPqb~jet\xspace processes are also determined. The value of the integrated cross section ratio measured in the combined channel is 0.100 $\pm$ 0.005 (stat) $\pm$ 0.007 (syst) $\pm$ 0.003 (theo). All of the measurements are compared with predictions from Monte Carlo simulations.
