The LHCb Mighty Tracker / Hennessy, Karol (Liverpool U.)
The LHCb detector is set to undergo a significant upgrade during theupcoming long shutdown 4 of the LHC. This upgrade will result in anearly tenfold increase in instantaneous luminosity, reaching $1.5\times 10^{34}\mathrm{cm^2s^{-1}}$, with an integrated luminosity expected to risefrom 50 $ \mathrm{fb^{-1}}$ to 300 $ \mathrm{fb^{-1}}$. [...]

Tests of Lepton Flavour Universality and searches for Lepton Flavour Violation at LHCb / López Huertas, Albert (ICC, Barcelona U.) /LHCb Collaboration
Rare $b \to s\ell^+\ell^−$ transitions are strongly suppressed in the Standard Model (SM). Leptons from the different families have the same coupling to electroweak bosons in the SM, symmetry that is known as Lepton Flavour Universality. [...]

Beam-beam interaction-induced bias to precision luminosity measurement / Wanczyk, Joanna (CERN ; Ecole Polytechnique, Lausanne) ; Buffat, Xavier (CERN) ; Dabrowski, Anne (CERN) ; Kozanecki, Witold (IRFU, Saclay) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne) ; Stickland, David (Princeton U.) ; Tomas Garcia, Rogelio (CERN) ; Wu, Yi (Ecole Polytechnique, Lausanne)
The mutual electromagnetic interaction between counter-rotating bunches crossing at the interaction points (IPs) of a particle collider has been studied since the dawn of the storage-ring era. It can result in a significant bias to absolute-luminosity calibrations determined by the van der Meer (vdM) method. [...]

Acceleration beyond lowest order event generation. An outlook on further parallelism within MadGraph5_aMC@NLO / Wettersten, Zenny (CERN ; Vienna, OAW) ; Mattelaer, Olivier (Louvain U., CP3) ; Roiser, Stefan (CERN) ; Schöfbeck, Robert (Vienna, OAW) ; Valassi, Andrea (CERN)
An important area of high energy physics studies at the Large Hadron Collider (LHC) currently concerns the need for more extensive and precise comparison data. Important tools in this realm are event reweighing and evaluation of more precise next-to-leading order (NLO) processes via Monte Carlo event generators, especially in the context of the upcoming High Luminosity LHC.

The integration of heterogeneous resources in the CMS Submission Infrastructure for the LHC Run 3 and beyond / Pérez-Calero Yzquierdo, Antonio (Madrid, CIEMAT ; PIC, Bellaterra) ; Mascheroni, Marco (UC, San Diego) ; Kizinevic, Edita (CERN) ; Khan, Farrukh Aftab (Fermilab) ; Kim, Hyunwoo (Fermilab) ; Flechas, Maria Acosta (Fermilab) ; Tsipinakis, Nikos (CERN) ; Haleem, Saqib (NCP, Islamabad) /CMS Collaboration
While the computing landscape supporting LHC experiments is currently dominated by x86 processors at WLCG sites, this configuration will evolve in the coming years. LHC collaborations will be increasingly employing HPC and Cloud facilities to process the vast amounts of data expected during the LHC Run 3 and the future HL-LHC phase. [...]

Repurposing of the Run 2 CMS High Level Trigger Infrastructure as a Cloud Resource for Offline Computing / CMS Collaboration
The former CMS Run 2 High Level Trigger (HLT) farm is one of the largest contributors to CMS compute resources, providing about 25k job slots for offline computing. This CPU farm was initially employed as an opportunistic resource, exploited during inter-fill periods, in the LHC Run 2. [...]

HPC resources for CMS offline computing: An integration and scalability challenge for the Submission Infrastructure / Pérez-Calero Yzquierdo, Antonio (Madrid, CIEMAT ; PIC, Bellaterra) ; Mascheroni, Marco (UC, San Diego) ; Kizinevic, Edita (CERN) ; Khan, Farrukh Aftab (Fermilab) ; Kim, Hyunwoo (Fermilab) ; Flechas, Maria Acosta (Fermilab) ; Tsipinakis, Nikos (CERN) ; Haleem, Saqib (NCP, Islamabad) /CMS Collaboration
The computing resource needs of LHC experiments are expected to continue growing significantly during the Run 3 and into the HL-LHC era. The landscape of available resources will also evolve, as High Performance Computing (HPC) and Cloud resources will provide a comparable, or even dominant, fraction of the total compute capacity.
