The strange quark content of the proton is probed through the measurement of the production cross section for a W boson and a charm (c) quark in p
We do so by including in the production function a flexible function of time whose parameterization depends on the firm. We also generalize the results of Hausman and Taylor (1981) to exploit assumptions about the uncorrelatedness of certain exogenous variables with the temporal pattern of the ...
PURPOSE:To make it possible to form chip shaped cross conductors stably at a low cost, by forming a plurality of insulating layers having specified widths, providing laminated bodies, and thereafter baking the laminated bodies at the same time. CONSTITUTION:Conductor films 12 are formed on one ...

Measurement of the ZZ production cross section in proton-proton collisions at √s=8 TeV using the ZZ→ℓ−ℓ+ℓ′−ℓ′+ and ZZ→ℓ−ℓ+νv̄ decay channels with the ATLAS detector 来自 sro.sussex.ac.uk 喜欢 0 阅读量: 76 作者:...
xs returns the (central cross section, (high error, low error)) for a center-of-mass energy [TeV], Higgs mass [GeV], and production mode. br returns the branching ratio for a Higgs mass [GeV] and decay channel. xsbr returns the cross section times branching ratio for a center-of-ma...
We present a measurement of the tt̅ production cross section in pp̅ collisions at √s = 1.8 TeV using an integrated luminosity of 109 pb-1 collected with the Collider Detector at Fermilab. The measurement uses tt̅ decays into final states which contain one or two high transverse momen...
This paper describes a measurement of the inclusive top quark pair production cross-section (σtt¯) with a data sample of 3.2fb−1 of proton–proton collisions at a centre-of-mass energy of s=13TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events wi...
Studied social interaction among 55 3–5 yr olds to examine the influence of sex on the communication strategies used by young children to initiate social contact and the success of such strategies. Naturally occurring social overtures in a preschool were recorded and coded by sex of initiator and...
