The CMS Outer Tracker for the High Luminosity LHC upgrade / La Rosa, Alessandro
The High Luminosity Large Hadron Collider (HL-LHC) at CERN is expected to collide protons at a centre-of-mass energy of 14\,TeV and to reach the unprecedented peak instantaneous luminosity of 5\,$-$\,7.5\,x\,$10^{34}$\,cm$^{-2}$s$^{-1}$ with an average number of pileup events of 140\,$-$\,200.

Setup and Characteristics of a Timing Reference Signal with sub-ps Accuracy for AWAKE / Batsch, Fabian
We describe a method to overcome the triggering jitter of a streak camera to obtain less noisy images of a self-modulated proton bunch over long time scales ($\sim$ 400 ps to ns) with the time resolution ($\sim$ 1 ps) of the short time scale images (73 ps). [...]

Measurement of the transverse momentum distribution of Drell-Yan lepton pairs in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
This paper describes precision measurements of the transverse momentum $p_\mathrm{T}^{\ell\ell}$ ($\ell=e,\mu$) and of the angular variable $\phi^{*}_{\eta}$ distributions of Drell-Yan lepton pairs in a mass range of 66-116 GeV. [...]

Measurement of the relative $B^{\pm}_{c}/B^{\pm}$ production cross section with the ATLAS detector at $\sqrt{s}=8$ TeV
The total cross section and differential cross sections for the production of $B_{c}^{\pm}$ mesons, times their branching fraction to $J/\psi \pi^{\pm}$, are measured relative to those for the production of $B^{\pm}$ mesons, times their branching fraction to $J/\psi K^{\pm}$. [...]

Level 1 Track Finder at CMS / Hart, Andrew Evan (Rutgers U., Piscataway)
The High-Luminosity LHC is expected to deliver proton-proton collisions every $25\,\mathrm{ns}{}$ with an estimated 140--200 pileup interactions per bunch crossing. Ultrafast track finding is vital for handling Level 1 trigger rates in such conditions. [...]

The CMS Tracker Upgrade for the High-Luminosity LHC / Migliore, Ernesto (INFN, Turin ; Turin U.) /CMS Collaboration
The LHC machine is planning an upgrade program, which will smoothly bring the instantaneous luminosity to about 5-7.5$\times10^{34}~\mathrm{cm}^{-2}\mathrm{s}^{-1}$ in 2028, to possibly reach an integrated luminosity of 3000-4500 fb$^{-1}$ by the end of 2039. This High-Luminosity LHC scenario, HL-LHC, will require a preparation program of the LHC detectors known as Phase-2 upgrade. [...]
