title: "Figure 23 (f)" 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 $t\bar{t}\gamma$ production differential cross-sections measured in fiducial phase space in the dilepton channel as a function of the $p_T(j_1)$. 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.
