 Search for the doubly charmed baryon $\Xi_{cc}^{+}$ / LHCb Collaboration A search for the doubly charmed baryon $\Xi_{cc}^{+}$ is performed through its decay to the $\Lambda_c^+ K^- \pi^+$ final state, using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13$\mathrm{\,Te\kern -0.1em V}$.

 Observation of several sources of $CP$ violation in $B^+ \to \pi^+ \pi^+ \pi^-$ decays / LHCb Collaboration Observations are reported of different sources of $CP$ violation from an amplitude analysis of $B^+ \to \pi^+ \pi^+ \pi^-$ decays, based on a data sample corresponding to an integrated luminosity of $3 \; {\rm fb}^{-1}$ of $pp$ collisions recorded with the LHCb detector.

 Fully hadronic ttH(bb) search / Ruiz Laborda, Guillermo (UZH) Characterising the associated production of top quark pairs and Higgs bosons (ttH process) at the LHC is the most direct way to study the top quark Yukawa coupling, a crucial parameter of the standard model of Particle Physics. For the forthcoming analysis of the full datasets collected by CMS during the LHC Run 2, it is imperative to optimise the analysis techniques to make sure the best possible sensitivity is attained [...] CERN-OPEN-2019-005.- Geneva : UZH, 2019 - 16 p.
