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. [...]

Isospin amplitudes in $\Lambda_b^0\to J/\psi \Lambda(\Sigma^0)$ and $\Xi_b^0\to J/\psi \Xi^0(\Lambda)$ decays
Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions, and allow searches for physics beyond the Standard Model. [...]

Exploring Supersymmetric CP Violation after LHC Run 2 with Electric Dipole Moments and B Observables / Arbey, A. ; Ellis, J. ; Mahmoudi, F.
We consider the prospects for measuring distinctive signatures of the CP-violating phases in the minimal supersymmetric extension of the Standard Model (MSSM) in light of the limits on sparticle masses from searches at the LHC. [...]
