Search for direct stau production in events with two hadronic $\tau$-leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector
A search for the direct production of the supersymmetric partners of $\tau$-leptons (staus) in final states with two hadronically decaying $\tau$-leptons is presented. [...]

Determination of quantum numbers for several excited charmed mesons observed in $B^- \to D^{*+} \pi^- \pi^-$ decays
A four-body amplitude analysis of the $B^- \to D^{*+} \pi^- \pi^-$ decay is performed, where fractions and relative phases of the various resonances contributing to the decay are measured. [...]

Higgs production in the VH mode at ATLAS and CMS / Mastrolorenzo, Luca (Aachen, Tech. Hochsch.) /ATLAS, CMS and Higgs collaborations
In these proceedings, the key role played by the Higgs boson associated production (VH) mode in the characterization of the electroweak spontaneous symmetry breaking mechanism is described through a review of the latest results from the ATLAS and CMS experiments obtained with the data collected during LHC Run 2. A focus is given to the recent discovery of the Higgs boson decay to a bottom quark-antiquark pair by ATLAS and CMS achieved through the analysis of the additional data collected during 2017. [...]

Multiplicity-dependent modification of $\chi_{c1}(3872)$ and $\psi{(2S)}$ production in $pp$ collisions at $\sqrt{s}$= 8 TeV /LHCb Collaboration
In $pp$ collisions at $\sqrt{s}$ = 8 TeV, $\chi_{c1}(3872)$ and $\psi{(2S)}$ states are produced promptly at the primary collision vertex or in decays of $b$~hadrons. We study their relative production rates as a function of particle multiplicity. [...]
