 Level 1 Track Finder at CMS / Hart, Andrew The High-Luminosity LHC is expected to deliver proton-proton collisions every 25 ns with an estimated 140-200 pileup interactions per bunch crossing. [...] arXiv:1910.06614. - Fulltext

 Quarkonium measurements at forward rapidity with ALICE at the LHC / Shaikh, Wadut Heavy quarks are produced at the first instant of a nucleus--nucleus collision and therefore are an important tool to study the subsequent high energy-density medium formed in ultra-relativistic heavy-ion collisions. [...] arXiv:1910.06695. - 4 p. Fulltext

 Black Hole State Dependence as a Single Parameter / van Breukelen, Rik (CERN ; Geneva U.) It has previously been proposed that the black hole interior of typical state large black holes in AdS can be described using state-dependent operators. [...] arXiv:1910.00036. - 29 p. Fulltext

 Firmware oriented trigger algorithm for CMS Drift Tubes in HL-LHC / Goy Lopez, Silvia (Madrid, CIEMAT) A full replacement of the muon trigger system in the CMS (Compact Muon Solenoid) detector is envisaged for operating at the maximum instantaneous luminosities expected in HL-LHC (High Luminosity Large Hadron Collider) of about $5-7.5\times10^{34}$~cm$^{-2}$s$^{-1}$. Under this scenario, the new on detector electronics that is being designed for the DT (Drift Tubes) detector will forward all the chamber information at its maximum time resolution.

 Level-1 track finding with an all-FPGA system at CMS for the HL-LHC / James, Thomas Owen (CERN) /CMS Collaboration The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) is designed to study a wide range of high energy physics phenomena. It employs a large all-silicon tracker within a 3.8\,T magnetic solenoid, which allows precise measurements of transverse momentum ($p_\mathrm{T}$) and vertex position.

 Emittance scans for CMS luminosity calibration in Run 2 / Karacheban, Olena (CERN) /CMS Collaboration The absolute luminosity calibration for LHC experiments is derived from dedicated beam separation scans, known as van der Meer (vdM) scans. However, vdM scans are performed with special beam optics, wide beams, and fewer, well-separated bunches to reduce potential systematic effects, and only once per year per collision mode.

 $\bf{\Lambda_{c}^{+}}$ production in pp and PbPb collisions at 5.02~TeV with the CMS detector / Xiao, Rui (Purdue U.) /CMS Collaboration Due to their large masses, the interactions of heavy quarks with the quark-gluon plasma (QGP) may be different from those of light quarks. The lightest charm baryon is the $\Lambda_{c}^{+}$, composed of a charm quark and two light quarks. [...] CMS-CR-2019-152.- Geneva : CERN, 2019 - 5 p.
