TL;DR: In this paper, the W boson mass was measured using 200 pb{sup -1} of {radical}s = 1.96 TeV p{bar p} collision data taken with the CDF II detector.
Abstract: We describe a measurement of the W boson mass m{sub W} using 200 pb{sup -1} of {radical}s = 1.96 TeV p{bar p} collision data taken with the CDF II detector. With a sample of 63,964 W {yields} e{nu} candidates and 51,128 W {yields} {mu}{nu} candidates, we measure m{sub W} = [80.413 {+-} 0.034(stat.) {+-} 0.034 (sys.) = 80.413 {+-} 0.048] GeV/c{sup 2}. This is the single most precise m{sub W} measurement to date. When combined with other measured electroweak parameters, this result further constrains the properties of new unobserved particles coupling to W and Z bosons.

TL;DR: In this paper, a measurement of the top quark-antiquark pair production cross section in proton-proton collisions at a centre-of-mass energy of 13
Abstract: A measurement of the top quark–antiquark pair production cross section $\sigma _{\mathrm {t}\overline{\mathrm {t}}} $ in proton–proton collisions at a centre-of-mass energy of 13 $\,\text {Te}\text {V}$ is presented. The data correspond to an integrated luminosity of $35.9{\,\text {fb}^{-1}} $ , recorded by the CMS experiment at the CERN LHC in 2016. Dilepton events ( $\mathrm {e}^{\pm }$ $\mathrm {\mu }^{{\mp }}$ , $\mathrm {\mu ^+}\mathrm {\mu ^-}$ , $\mathrm {e}^+\mathrm {e}^-$ ) are selected and the cross section is measured from a likelihood fit. For a top quark mass parameter in the simulation of $ m_\mathrm {\mathrm {t}} ^{\mathrm {MC}} = 172.5 \,\text {Ge}\text {V} $ the fit yields a measured cross section $\sigma _{\mathrm {t}\overline{\mathrm {t}}} = 803 \pm 2 \,\text {(stat)} \pm 25 \,\text {(syst)} \pm 20 \,\text {(lumi)} \,\text {pb} $ , in agreement with the expectation from the standard model calculation at next-to-next-to-leading order. A simultaneous fit of the cross section and the top quark mass parameter in the powheg simulation is performed. The measured value of $m_\mathrm {\mathrm {t}} ^{\mathrm {MC}} = 172.33 \pm 0.14 \,\text {(stat)} \,^{+0.66-0.72} \,\text {(syst)} \,\text {Ge}\text {V} $ is in good agreement with previous measurements. The resulting cross section is used, together with the theoretical prediction, to determine the top quark mass and to extract a value of the strong coupling constant with different sets of parton distribution functions.

TL;DR: In this paper, the Level-1 trigger was used to select cosmic ray muons and LHC beam events during data-taking runs in 2008, and to estimate the level of detector noise.
Abstract: The CMS Level-1 trigger was used to select cosmic ray muons and LHC beam events during data-taking runs in 2008, and to estimate the level of detector noise. This paper describes the trigger components used, the algorithms that were executed, and the trigger synchronisation. Using data from extended cosmic ray runs, the muon, electron/photon, and jet triggers have been validated, and their performance evaluated. Efficiencies were found to be high, resolutions were found to be good, and rates as expected.

TL;DR: It is argued that the incorporation of social media into daily practice also creates opportunities for journalists to garner peer recognition and that these opportunities vary according to the distinctive national fields in which journalists are embedded.
Abstract: This article examines journalists’ use of social media in France and the United States. Through in-depth interviews, we show that shared practical sensibilities lead journalists in both countries t...
