Machine Learning in High Energy Physics Community White Paper / Albertsson, Kim (Lulea U.) ; Altoe, Piero (NVIDIA, Santa Clara) ; Anderson, Dustin (Caltech) ; Anderson, John ; Andrews, Michael (Carnegie Mellon U.) ; Araque Espinosa, Juan Pedro (LIP, Lisbon) ; Aurisano, Adam (Cincinnati U.) ; Basara, Laurent (INFN, Padua ; Padua U.) ; Bevan, Adrian (University Coll. London) ; Bhimji, Wahid (LBL, Berkeley) et al.
Machine learning has been applied to several problems in particle physics research, beginning with applications to high-level physics analysis in the 1990s and 2000s, followed by an explosion of applications in particle and event identification and reconstruction in the 2010s. In this document we discuss promising future research and development areas for machine learning in particle physics. [...]

HTTP as a Data Access Protocol: Trials with XrootD in CMS’s AAA Project / Balcas, J (Caltech) ; Bockelman, B P (Nebraska U.) ; Kcira, D (Caltech) ; Newman, H (Caltech) ; Vlimant, J (Caltech) ; Hendricks, T W (Caltech) /CMS
The main goal of the project to demonstrate the ability of using HTTP data federations in a manner analogous to the existing AAA infrastructure of the CMS experiment. An initial testbed at Caltech has been built and changes in the CMS software (CMSSW) are being implemented in order to improve HTTP support. [...]

Measurement of the mass difference between top quark and antiquark in pp collisions at $\sqrt{s} = 8$ TeV / CMS Collaboration
The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Delta m[t] = m[t] - m[t-bar]) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron and at least four jets in the final state.

Measurement of jet fragmentation in PbPb and pp collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / CMS Collaboration
The jet fragmentation function of inclusive jets with transverse momentum $p_T$ above 100 GeV/c in PbPb collisions has been measured using reconstructed charged particles with $p_T$ above 1 GeV/c in a cone of radius 0.3 around the jet axis. A data sample of PbPb collisions collected in 2011 at a nucleon-nucleon center-of-mass energy of $\sqrt{s_{NN}}$ = 2.76 TeV corresponding to an integrated luminosity of 150 inverse-microbarns is used.

Measurements of the inclusive jet cross section with the anti-$k_t$ clustering algorithm are presented for two radius parameters, R=0.5 and 0.7. They are based on data from LHC proton-proton collisions at $\sqrt{s}$ = 7 TeV corresponding to an integrated luminosity of 5.0 inverse-femtobarns collected with the CMS detector in 2011. [...]

Description and performance of track and primary-vertex reconstruction with the CMS tracker / CMS Collaboration
A description is provided of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the positions of the LHC luminous region and individual primary-interaction vertices. Despite the very hostile environment at the LHC, the performance obtained with these algorithms is found to be excellent. [...]
