Measurement of the integrated and differential $\mathrm{t \bar{t}}$ production cross sections for high-$p_{\mathrm{T}}$ top quarks in pp collisions at $ \sqrt{s} = $ 8 TeV
The cross section for pair production of top quarks with high transverse momenta (pt > 400 GeV) is The cross section for pair production of top quarks ($\mathrm{ t \bar{t} }$) with high transverse momenta is measured in $\mathrm{ p } \mathrm{ p }$ collisions, collected with the CMS detector at the LHC with $ \sqrt{s} = $ 8 TeV in data corresponding to an integrated luminosity of 19.7 fb$^{-1}$.

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. [...]
