title: "Table 9" of "Search for pair production of vector-like quarks in leptonic final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Numbers of predicted and observed SR events in 2017--2018 data in the same-sign dilepton channel, after a background-only fit to data. Predicted numbers of signal events before the fit to data are included for comparison, using the singlet branching fraction scenario. Uncertainties include statistical and systematic components. Predictions for 2017 and 2018 are combined with their uncertainties added in quadrature.
description: A search is presented for vector-like T and B quark-antiquark pairs produced in proton-proton collisions at a center-of-mass energy of 13 TeV. Data were collected by the CMS experiment in 2016–2018, with an integrated luminosity of 138/fb. Events are separated into single-lepton, same-sign dilepton, and multi-lepton channels. The single-lepton channel uses a multilayer neural network and jet identification techniques to select signal events, while the same-sign dilepton and multilepton channels rely on the high-energy signature of the signal to distinguish it from rare standard model backgrounds. The data are consistent with standard model background predictions, and the production of vector-like quark pairs is excluded at 95% confidence level for T quark masses up to 1.54 TeV and B quark masses up to 1.56 TeV, depending on the branching fractions assumed, with maximal sensitivity to decay modes that include multiple top quarks. These are the strongest limits to date for TT production, excluding masses below 1.47 TeV for all decays to third generation quarks, as well as for BB production with B quark decays to tW.

title: "Figure 4 top" of "Search for flavour-changing neutral-current couplings between the top quark and the photon with the ATLAS detector at $\sqrt{s} = 13$ TeV"

description: Post-fit distribution of a background-only fit to the NN discriminant in the SR for the $tu\gamma$ coupling. The last bin of the distribution contains the overflow and the first bin also contains the underflow. In addition, the expected $tu\gamma$ LH signal is overlaid for an expected number of events corresponding to the observed 95% CL limit scaled by a factor of ten. The uncertainty band includes both the statistical and systematic uncertainties in the background prediction as well as the correlations of the uncertainties as obtained by the fit.
description: Search for flavour-changing neutral-current couplings between the top-quark and the photon with the ATLAS detector at $\sqrt{s} = 13$ TeV

The analysis uses data collected in $pp$ collisions at $\sqrt{s} = 13$~TeV during the LHC Run 2 corresponding to an integrated luminosity of 139~fb$^{-1}$.
Both FCNC top-quark production and decay are considered.
The final state consists of a charged lepton, missing transverse momentum, a $b$-tagged jet, one high momentum photon and possibly additional jets.
A multiclass deep neural network is used to classify events as either one of the two signal categories, FCNC production or decay, or as background.
