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. [...]

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.
