Mechanical stability of the CMS strip tracker measured with a laser alignment system
(IOP Publishing, 2017-04-21)
The CMS tracker consists of 206 m2 of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from −25 to +25°C. The mechanical stability of tracker ...
Measurement of the semileptonic t t ¯ + γ production cross section in pp collisions at √s=8 TeV
(Springer International Publishing, 2017-10-02)
A measurement of the cross section for top quark-antiquark ( tt¯tt¯ ) pairs produced in association with a photon in proton-proton collisions at s√=8s=8 TeV is presented. The analysis uses data collected with the CMS ...
Study of jet quenching with Z + jet correlations in Pb-Pb and pp collisions at √sNN=5.02TeV
(American Physical Society, 2017-08-23)
The production of jets in association with Z bosons, reconstructed via the mu(+)mu(-) and e(+)e(-) decay channels, is studied in pp and, for the first time, in Pb-Pb collisions. Both data samples were collected by the CMS ...
Measurement of charged pion, kaon, and proton production in proton-proton collisions at √s=13 TeV
(American Physical Society, 2017-12-05)
Transverse momentum spectra of charged pions, kaons, and protons are measured in proton-proton collisions at root s = 13 TeV with the CMS detector at the LHC. The particles, identified via their energy loss in the silicon ...
Measurements of the pp → Wγγ and pp → Zγγ cross sections and limits on anomalous quartic gauge couplings at √s = 8 TeV
(Springer International Publishing, 2017-10-11)
Measurements are presented of Wγγ and Zγγ production in proton-proton collisions. Fiducial cross sections are reported based on a data sample corresponding to an integrated luminosity of 19.4 fb−1 collected with the CMS ...
Search for black holes and other new phenomena in high-multiplicity final states in proton–proton collisions at √s = 13 TeV
(Elsevier, 2017)
A search for new physics in energetic, high-multiplicity final states has been performed using proton-proton collision data collected with the CMS detector at a center-of-mass energy of 13 TeV and corresponding to an ...
