 Probing QCD using top quark pair production at $\sqrt{s} = 13~\mathrm{TeV}$ in CMS / Defranchis, Matteo M. Measurements of the top quark-antiquark pair production cross section, $\sigma_\mathrm{t\bar{t}}$, can be used to constrain the strong coupling constant, $\alpha_{S}$, the top quark mass, $m_\mathrm{t}$, and the parton distribution functions (PDFs).

 Vertex and Tracking Detector R&D for CLIC / Munker, Magdalena (CERN) The physics goals at the proposed future Compact Linear Collider (CLIC) pose challenging demands on the performance of the detector system. Precise hit-time tagging with a few nanoseconds resolution is required for the vertex and tracking detectors, as well as a very low mass per layer combined with a single-plane spatial resolution of a few micrometers.
