Charged multiplicity measurement for simulated pp events in the Compact Muon Solenoid (CMS) detector
… multiplicity of proton-proton collisions in the Compact Muon Solenoid (CMS) experiment at LHC energies ... This technique involves counting reconstructed hits in the innermost layer of the pixel tracker. By using the relationship between pseudorapidity and deposited charge of the hits, we can …

Modeling exascale data generation and storage for the large hadron collider computing network
… produced at the LHC and measured with the Compact Muon Solenoid (CMS) detector, the CMS experimental group performs precision measurements and general searches for new physics. Year-round CMS operations produce 100 Petabytes of physics data per year, which is stored within a globally …

Electron identification and ZZ -->4l̳ (e̳, [mu]) cross section measurement with the CMS detector
… using generator-level information in the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC). In particular, we carry out three central investigations: the determination of electron efficiencies, electron fake rates, and ZZ -->4l(e, [mu]) cross sections. Reconstructed Z …

A study of tau identification with the CMS detector at the LHC
… reconstructed data that will be collected by the Compact Muon Solenoid (CMS) detector on the Large Hadron Collider (LHC) at CERN. The two components of particle identification, efficiencies of [tau] identification from generator level information, along with fake rates of the current default …

Studies of Jet Modification in Heavy Ion Collisions with the CMS Experiment
In the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC), lead ions are collided at ultra-relativistic velocities to produce Quark-Gluon Plasma (QGP), a state of matter where quarks and gluons are deconfined and move collectively. Jets are produced in high-momentum transfer …

Diboson physics with CMS detector
… of di-boson production in pp collision with the Compact Muon Solenoid (CMS) detector at Large Hadron Collider (LHC). A study of Z+gamma process is performed on the data collected by the CMS during 2011 and corresponding to integrated luminosity L= 5 fb[superscript]-1. The study consists of two …

Neural-Network Based b-Tagging in the CMS Level 1 Trigger System
The Phase II upgrade of the Compact Muon Solenoid (CMS) detector for the High Luminosity Large Hadron Collider will greatly expand the hardware capabilities of the Level 1 Trigger (L1T) system. With the advent of tracks in the L1T, these upgrades bring the idea of b jet identification within the …

DIRECTED AND ELLIPTIC FLOW MEASUREMENTS: A COMPARISON BETWEEN THE PARTICIPANT AND SPECTATOR PLANES IN Pb+Pb COLLISIONS AT √sNN = 5.02 TeV WITH CMS AT THE LHC
… and spectator neutrons measured with the Compact Muon Solenoid (CMS) detector and the newly installed Spectator Reaction Plane Detector (SRPD), respectively. The SRPD is the latest addition to the existing Zero Degree Calorimeter (ZDC) designed to measure spectator neutrons +/- 140 m from …

Partonic rescatterings during jet fragmentation in the QCD vacuum
… for partonic collectivity inside jets using the Compact Muon Solenoid (CMS) detector at the LHC. We compare results from data to two MC simulations employing different phenomenological models. Deviations between data and both MC simulations are observed, in accordance with our initial postulate. …

First search for electroweak supersymmetry in final states with hadronic decays of WW, WZ, or WH boson pair and missing transverse momentum.
… search is performed using Run 2 data from the CMS experiment at the LHC with a total integrated luminosity of 137 fb−1 . The targeted final states include a pair of bosons (WW, WZ, or WH) with large missing transverse momentum arising from the lightest neutralinos (χe 0 1 ). Deep neural network …
