Journal ArticleDOI

A Deep Neural Network for Simultaneous Estimation of b Jet Energy and Resolution.

Albert M. Sirunyan, +2276 more
- 30 Oct 2020 - 
TL;DR: A multivariate regression algorithm based on a deep feed-forward neural network employs jet composition and shape information, and the properties of reconstructed secondary vertices associated with the jet, to improve the sensitivity of analyses that make use of b jets in the final state.
Journal ArticleDOI

Calibration of the CMS drift tube chambers and measurement of the drift velocity with cosmic rays

S. Chatrchyan, +2464 more
- 01 Dec 2010 - 
TL;DR: In this paper, the main goal of the calibration procedure is to determine, for each drift cell, the minimum time delay for signals relative to the trigger, accounting for the drift velocity within the cell.
Journal ArticleDOI

Search for new physics in final states with a lepton and missing transverse energy in pp collisions at the LHC

S. Chatrchyan, +2204 more
- 08 Apr 2013 - 
TL;DR: In this paper, the authors describe the search for an enhanced production rate of events with a charged lepton and a neutrino in high-energy pp collisions at the LHC, and interpret the results in terms of limits on a heavy charged gauge boson (W′) in the sequential standard model, a split universal extra dimension model and contact interactions in the helicity-nonconserving model.
Journal ArticleDOI

Measurement of the top quark mass with lepton+jets final states using p p collisions at √s=13TeV

Albert M. Sirunyan, +2279 more
- 03 May 2018 - 
TL;DR: The mass of the top quark was measured using a sample of events collected by the CMS detector using proton-proton collisions at the CERN LHC as discussed by the authors, and no indications of a bias in the measurements are observed.
Journal ArticleDOI

Heritability and responses to high fat diet of plasma lipidomics in a twin study

Turid Frahnow, +7 more
- 16 Jun 2017 - 
TL;DR: Basal concentrations of specific lipids within phospholipids are strongly inherited and are likely to be associated with heritable disease risks, and Nutrition strongly alters specific lipid classes, and has to be controlled in clinical association studies.
