 Triangular flow of negative pions emitted in PbAu collisions at $\sqrt{s_{NN}}$= 17.3~GeV / for the CERES/NA45 collaboration Differential triangular flow, $v_3(p_T)$, of negative pions is measured at $\sqrt{s_{NN}}$= 17.3~GeV around midrapidity by the CERES/NA45 experiment at CERN in central PbAu collisions in the range 0-30\% with a mean centrality of 5.5\%.

 Theory Advances in BSM Physics / McCullough, Matthew (CERN) Rather than attempting to summarise the full spectrum of recent advances in Beyond the Standard Model (BSM) theory, which are many, in this talk I will instead take the opportunity to focus on two frameworks related to the hierarchy problem currently receiving significant attention.

 A Highly Selective First-Level Muon Trigger With MDT Chamber Data for ATLAS at HL-LHC / Kroha, H (Munich, Max Planck Inst.) Highly selective triggers are essential for the physics programme of the ATLAS experiment at HL-LHC where the instantaneous luminosity will be about an order of magnitude larger than the LHC instantaneous luminosity in Run 1.

 Strangeness production as a function of charged particle multiplicity in proton-proton collisions / Bianchi, Livio (Houston U.) Recent measurements performed in high-multiplicity proton-proton (pp) and proton-lead (p-Pb) collisions have shown features that are reminiscent of those observed in lead-lead (Pb-Pb) collisions.

 Digamma, what next? / Franceschini, Roberto (CERN) ; Giudice, Gian F (CERN) ; Kamenik, Jernej F (CERN ; Stefan Inst., Ljubljana ; Ljubljana U.) ; McCullough, Matthew ; Riva, Francesco (CERN) ; Strumia, Alessandro (CERN ; Pisa U. ; INFN, Pisa) ; Torre, Riccardo (LPHE, Lausanne) If the 750 GeV resonance in the diphoton channel is confirmed, what are the measurements necessary to infer the properties of the new particle and understand its nature? We address this question in the framework of a single new scalar particle, called digamma ($\digamma$). [...] arXiv:1604.06446 ; CERN-TH-2016-090. - 2016. - 51 p. Preprint - Full text
