$t\bar{t}$+heavy flavour measurements with the full run 2 dataset using the ATLAS experiment / Morais Silva Goncalo, Ricardo Jose (Laboratory of Instrumentation and Experimental Particle Physics (PT))
The production of top quark pairs in association with heavy-flavour jets ($b/c$) is a difficult process to calculate and model, and is one of the leading sources of background affecting the measurement of processes such as the associated production of a Higgs boson and a top-quark pair, $t\bar{t}H$ [...]

Recent lepton flavour results from ATLAS / Wilson, Benjamin James (The University of Manchester (GB)) /ATLAS Collaboration
Lepton flavour violation (LFV), and lepton flavour university violation (LFUV), are a striking signature of potential beyond the Standard Model physics. This talk presents recent searches and tests for LFV and LFUV with the ATLAS detector, using proton-proton collisions with a centre of mass energy of 13 TeV. [...]

First determination of the spin-parity of ${\Xi}_{c}(3055)^{+0}$ baryons / LHCb Collaboration
The ${{\Xi}_{b}^{0(-)}\to{\Xi}_{c}(3055)^{+(0)}(\to D^{+(0)}{\Lambda}){\pi}^{-}}$ decay chains are observed, and the spin-parity of ${\Xi}_{c}(3055)^{+(0)}$ baryons is determined for the first time. [...]

Searches for new physics with leptons using the ATLAS detector / Koch, Simon Florian (University of Oxford (GB)) /ATLAS Collaboration
Many different theories beyond the Standard Model (SM) predict that new physics will manifest itself by decaying into final states involving leptons. Leptoquarks are predicted by many new physics theories to describe the similarities between the lepton and quark sectors of the SM. [...]

Searches for lepton-flavour-violating decays of the Higgs boson into 𝑒𝜏 and 𝜇𝜏 in sqrt{𝑠}= 13 TeV 𝑝𝑝 collisions with the ATLAS detector / Chu, Michael Kwok Lam (Weizmann Institute of Science (IL)) /ATLAS Collaboration
This poster presents the results of a direct search for lepton-flavour-violating decays of the Higgs boson into e tau and mu tau final states with the ATLAS detector at the LHC with Run 2 data. Both leptonically and hadronically decaying tau leptons are included and two different background estimation techniques are employed: a MC-template method, based on data-corrected simulation samples, and a data-driven method, based on exploiting the symmetry between electrons and muons in the Standard Model backgrounds. [...]

Search for $B_{(s)}^{*0}\to\mu^+\mu^-$ in $B_c^+\to\pi^+\mu^+\mu^-$ decays /LHCb Collaboration
A search for the very rare $B^{*0}\to\mu^+\mu^-$ and $B_{s}^{*0}\to\mu^+\mu^-$ decays is conducted by analysing the $B_c^+\to\pi^+\mu^+\mu^-$ process. The analysis uses proton-proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9\,fb$^{-1}$ [...]
