title: "Table 20" of "Measurement of Multijet Production in ep Collisions at High Q^2 and Determination of the Strong Coupling alpha_s"

description: Double-differential normalised trijet cross sections measured as a function of Q**2 and XI(3) using the anti-kT jet algorithm. The total systematic uncertainty sums all systematic uncertainties in quadrature, including the uncertainty due to the LAr noise of 0.9% and the total normalisation uncertainty of 2.9%. The correction factors on the theoretical cross sections C(HAD) and C(EW) are listed in the rightmost columns.
description: DESY-HERA. Inclusive jet, dijet and trijet differential cross sections are measured in neutral current deep-inelastic scattering for exchanged boson virtualities 150 &lt; Q**2 &lt; 15000 GeV**2 using the H1 detector at HERA. The data were taken in the years 2003 to 2007 and correspond to an integrated luminosity of 351 pb^{-1}. 

Double differential jet cross sections are obtained using a regularised unfolding procedure. They are presented as a function of Q**2 and the transverse momentum of the jet, PT(JET), and as a function of Q**2 and the proton longitudinal momentum fraction, XI, carried by the parton participating in the hard interaction. In addition normalised double differential jet cross sections are measured as the ratio of the jet cross sections to the inclusive neutral current cross sections in the respective Q**2 bins of the jet measurements. 

In dijet and trijet cross section measurements the variables used are labelled MEAN(PT(2JET)) and XI(2), and MEAN(PT(3JET)) and XI(3), respectively. These are defined as: 
 - MEAN(PT(2JET)) = (1/2) * ( PT(JET(1)) + PT(JET(2)) ). 
 - MEAN(PT(3JET)) = (1/3) * ( PT(JET(1)) + PT(JET(2)) + PT(JET(3)) ). 
 - XI(2) = X * ( 1 + (M(12)**2 / Q**2) ) where X is the Bjorken scaling variable and M(12) is the invariant mass of the two leading jets. 
 - XI(3) = X * ( 1 + (M(123)**2 / Q**2) ) where M(123) is the invariant mass of the three leading jets. 

Compared to earlier work, the measurements benefit from an improved reconstruction and calibration of the hadronic final state. The cross sections are compared to perturbative QCD calculations in next-to-leading order and are used to determine the running coupling and the value of the strong coupling constant as ALPHAS(M(Z)) = 0.1165 +- 0.0008 (exp) +- 0.0038 (pdf,theo).

title: "Table 1" of "Exclusive $\mathrm{J/}\psi$ photoproduction off protons in ultra-peripheral p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV"

description: Differential cross sections as a function of rapidity for exclusive J/PSI photoproduction off protons in ultra-peripheral p-Pb collisions. The corresponding J/PSI photoproduction cross sections in bins of the GAMMA-P centre-of-mass, W(GAMMA P), are also presented.
description: CERN-LHC. We present the first measurement at the LHC of exclusive J/PSI photoproduction off protons, in ultra-peripheral proton-lead collisions at sqrt(sNN) = 5.02 TeV. Events are selected with a dimuon pair produced either in the rapidity interval, in the laboratory frame, 2.5 &lt; YRAP &lt; 4 (p-Pb) or -3.6 &lt; y &lt; -2.6 (Pb-p), and no other particles observed in the ALICE acceptance. The data set used in this analysis corresponds to an integrated luminosity of 3.9 nb^{-1} +- 3.2% (syst) for p-Pb collisions and 4.5 nb^{-1} +- 3.0% (syst) for Pb-p collisions. 

The measured cross sections SIGMA(GAMMA P --&gt; J/PSI P) are 33.2 +- 2.2 (stat) +- 3.1 (syst) +- 0.7 (theo) nb in p-Pb and 284 +- 36 (stat) +27,-32 (syst) +- 26 (theo) nb in Pb-p collisions. We measure this process up to about 700 GeV in the GAMMA-P centre-of-mass, which is a factor of two larger than the highest energy studied at HERA. The cross section as a function of the GAMMA-P centre of mass, W(GAMMA P), and the differential cross section as a function of rapidity are also presented along with the product of the photon energy, K, and the photon flux, DN/DK.

title: "Table 1" of "Comprehensive measurements of $t$-channel single top-quark production cross sections at $\sqrt{s} = 7$ TeV with the ATLAS detector"

description: Differential t-channel top-quark production cross sections and normalized differential t-channel top-quark production cross sections as functions of PT(TOP).
description: CERN-LHC. This article presents measurements of the t-channel single top-quark and top-antiquark total production cross sections SIG(TOP) and SIG(TOPBAR), their ratio R = SIG(TOP)/SIG(TOPBAR), and a measurement of the inclusive production cross section SIG(TOP + TOPBAR) in proton-proton collisions at sqrt(s) = 7 TeV at the LHC. Differential cross sections for the top-quark and top-antiquark processes are measured as a function of the transverse momentum and the absolute value of the rapidity of TOP and TOPBAR, respectively. The analyzed data set was recorded with the ATLAS detector and corresponds to an integrated luminosity of 4.59 fb^{-1}. 

Selected events contain one electron or muon, large missing transverse momentum, and two or three jets. The cross sections are measured by performing a binned maximum-likelihood fit to the output distributions of neural networks. The resulting measurements are SIG(TOP) = 46 +- 6 pb, SIG(TOPBAR) = 23 +- 4 pb, R = 2.04 +- 0.18, and SIG(TOP + TOPBAR) = 68 +- 8 pb, consistent with the Standard Model expectation. The uncertainty on the measured cross sections is dominated by systematic uncertainties, while the uncertainty on R is mainly statistical. 

Using the ratio of SIG(TOP + TOPBAR) to its theoretical prediction, and assuming that the top-quark-related CKM matrix elements obey the relation ABS(V(TB)) &gt;&gt; ABS(V(TS)), ABS(V(TD)), we determine ABS(V(TB)) = 1.02 +- 0.07.
