 New results on collectivity in small systems with CMS / Milosevic, Jovan (VINCA Inst. Nucl. Sci., Belgrade) /CMS Collaboration The elliptic ($\upsilon_{2}$) flow of prompt D$^{0}$ mesons, together with K$^{0}_{S}$, $\Lambda$, $\Xi$, and $\Omega$ in high-multiplicity pPb collisions at 8.16~TeV, is presented. The data are collected with the CMS detector at the LHC from the rapidity interval $-1.46 < y_{cm} < 0.54$ and transverse momentum range 1.5 $< \mathrm{p_{T}} <$ 8~GeV.

 Experimental results using the decay of the Higgs to taus and muons / Meyer, Mareike (DESY) /ATLAS and CMS Collaborations Precise measurements of the Higgs boson Yukawa couplings provide important tests of the Standard Model of particle physics. This review summarizes the current status of the analyses performed by the ATLAS and CMS experiments that search for the Higgs boson decay into a pair of muons.

 SEARCHES FOR DARK MATTER PARTICLES AT THE LHC / Felcini, Marta (University Coll., Dublin) /ATLAS ,CMS and SUSY Collaborations The searches for new particles that could be constituents of the dark matter in the universe are an essential part of the physics program of the experiments at the Large Hadron Collider. An overview of recent dark matter candidate searches is presented with a focus on new results obtained by the ATLAS and CMS experiments from the analysis of the proton-proton collision data at 13 TeV center-of-mass energy collected in the first part of Run 2..
