title: "Figure 25 (b)" of "Measurements of inclusive and differential cross-sections of $t\bar{t}\gamma$ production in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Normalised differential cross-section of the total $t\bar{t}\gamma$ production and decay measured in fiducial phase space in the dilepton channel as a function of the $\Delta R(\gamma,b)_{min}$. The last bin of the distribution includes the overflow events.
description: CERN-LHC-ATLAS. Inclusive and differential cross-sections are measured at particle level for the associated production of a top-quark pair and a photon ($t\bar{t}\gamma$). The analysis is performed using an integrated luminosity of 140 fb$^{−1}$ at a centre-of-mass energy of 13 TeV collected using the ATLAS detector. The measurements are performed in the single-lepton and dilepton top-quark pair decay channels focusing on $t\bar{t}\gamma$ topologies where the photon is radiated from an initial-state parton or one of the top quarks. The photon transverse momentum differential distribution is used to set limits on effective field theory parameters related to the electroweak dipole moments of the top quark. The combined limits using the photon and the $Z$-boson transverse momentum measured in $t\bar{t}$ production in associations with a $Z$ boson are also set.

 The fiducial region in single-lepton (dilepton) channel is defined as:
- Exactly one (two) electron or muon with p$_{\text{T}} &gt; 25$ GeV and $|\eta| &lt; 2.5$ which do not originate from hadron decays. Events are rejected if there are additional leptons with $p_{ ext{T}} &gt; 7$ GeV.
- Exactly one photon with E$_{\text{T}} &gt; 20$ GeV and $|\eta| &lt; 2.37$, and the sum of transverse momenta of all charged particles surrounding the photon within $\Delta R = 0.2$ is less than 5% of its own p$_\text{T}$.
- $\geq$ four (two) jets, which have p$_{\text{T}} &gt; 25$ GeV and $|\eta| &lt; 2.5$. Jets are clustered with the anti-$k_t$ algorithm with a radius parameter of $R = 0.4$. All stable particles are considered in the clustering, except for the selected electrons, muons and photons, and the neutrinos originating from the top quarks.
- $\geq$ 1 b-tagged jet. A jet is identified as a b-jet if a hadron with p$_T &gt; 5$ GeV containing a b-quark is matched to the jet through a ghost-matching method.
- Muons and electrons within $\Delta R &lt; 0.4$ from a jet are excluded. 
- Jets within $\Delta R = 0.4$ of an isolated photon candidate are excluded. 
- Events must satisfy $\Delta R(\gamma,l) &gt; 0.4$, where $l$ is the electron or muon.

title: "Figure 2 (upper left)" of "Search for resonant pair production of Higgs bosons in the $\mathrm{b\bar{b}b\bar{b}}$ final state using large-area jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Slices of 2D distributions of observed events and the post-fit templates in the LL pass region, projected onto the plane of leading jet mass mJ1, including expected radion signal at 1.5 TeV.
description: A search is presented for the resonant production of a pair of the standard model-like Higgs bosons using data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected by the CMS experiment at the CERN LHC in 2016--2018, corresponding to an integrated luminosity of 138 $\mathrm{fb}^{-1}$. The final state consists of two b quark-antiquark pairs. The search is conducted in the region of phase space where at least one of the pairs is highly Lorentz-boosted and is reconstructed as a single large-area jet. The other pair may be either similarly merged or resolved, the latter reconstructed using two b-tagged jets. The data is found to be consistent with the measured standard model processes and are interpreted as 95% confidence level upper limits on the product of the cross sections and the branching fractions of the spin-0 radion and the spin-2 bulk graviton in warped extradimensional models. The limits set are in the range 9.74--0.29 fb and 4.94--0.19 fb for a narrow radion and a graviton, respectively, with a mass between 1 and 3 TeV. For a 10%-width radion and a bulk graviton, the limits are in the range 12.5--0.35 fb and 8.23--0.23 fb, respectively, for the same masses. These limits result in the exclusion of the narrow-width graviton with a mass below 1.2 TeV, and of the narrow and 10%-width radion with masses below 2.6 TeV, and 2.8 TeV, respectively, an improvement of $\approx$1 TeV over the previous CMS measurement.
