At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-of-mass energy of 13 TeV. During Run 2 (years 2015-2018) the LHC eventually reached a luminosity …

At the CERN LHC, instantaneous luminosities of up to 1.5× 1034 cm− 2 s− 1 [1] are sufficiently large for multiple proton-proton (pp) collisions to occur in the same time window …
A bstract Pileup involves the contamination of the energy distribution arising from the primary collision of interest (leading vertex) by radiation from soft collisions (pileup). We …
The performance of missing transverse momentum (${\vec p} _ {\mathrm {T}}^\mathrm {miss} $) reconstruction algorithms for the CMS experiment is presented, using proton-proton …
The CMS detector at the LHC has recorded events from proton-proton collisions, with muon momenta reaching up to 1.8 TeV in the collected dimuon samples. These high-momentum …
The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC …

A bstract We propose a new method for pileup mitigation by implementing “pileup per particle identification”(PUPPI). For each particle we first define a local shape α which probes …

The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 pb− 1 of data collected in pp collisions at√ s= 7 TeV at the LHC in 2010. A …
