Under-coverage in high-statistics counting experiments with finite MC samples Open
We consider the problem of setting confidence intervals on a parameter of interest from the maximum-likelihood fit of a physics model to a binned data set with a large number of bins, large event-counts per bin, and in the presence of syst…

HL-LHC Computing Review: Common Tools and Community Software Open
Common and community software packages, such as ROOT, Geant4 and event generators have been a key part of the LHC's success so far and continued development and optimisation will be critical in the future. The challenges are driven by an a…

Suppression of Excited Y States Relative to the Ground State in Pb-Pb Collisions at √s$_{NN}$ = 5,02 TeV Open
The relative yields of Υ mesons produced in pp and Pb-Pb collisions at √sNN=5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields o…

Efficient Monte Carlo Integration Using Boosted Decision Trees and Generative Deep Neural Networks Open
New machine learning based algorithms have been developed and tested for Monte Carlo integration based on generative Boosted Decision Trees and Deep Neural Networks. Both of these algorithms exhibit substantial improvements compared to exi…

Charged-particle nuclear modification factors in PbPb and pPb collisions at √sNN−−−− = 5.02 TeV Open
The spectra of charged particles produced within the pseudorapidity window |η| < 1 at s NN √sNN =5.02 TeV are measured using 404 μb−1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in 2015. The spectra are presen…

Scalar Boson: CMS Run 1 final results, prospectives for Run 2 (and HL-LHC) Open
Results are presented for the main standard model Higgs boson channels from the CMS experiment at the LHC. Results in the $\\tau\\tau$ and $WW\\rightarrow 2\\ell 2\\nu$ final states constitute standalone evidences, and results in the $H\\r…
