title: "Table 12" of "Measurement of the low-mass Drell-Yan differential cross section at sqrt(s)=7 TeV using the ATLAS detector"

description: Values of chi^2 for the nominal and extended DY cross-section measurements for predictions based from Fewz at NLO and NNLO and Powheg using MSTW2008 PDFs accounting for the experimental correlated systematic uncertainties. The _pdf_scale columns show the chi^2 when the PDF and scale uncertainties on the theoretical predictions are taken into account.
description: CERN-LHC. The differential cross section for the process Z/gamma*-&gt;ll (l=e,mu) as a function of dilepton invariant mass is measured in pp collisions at sqrt(s) = 7 TeV at the LHC using the ATLAS detector. The measurement is performed in the e and mu channels for invariant masses between 26 GeV and 66 GeV using an integrated luminosity of 1.6 fb^-1 collected in 2011 and these measurements are combined. The analysis is extended to invariant masses as low as 12 GeV in the muon channel using 35 pb^-1 of data collected in 2010. The cross sections are determined within fiducial acceptance regions and corrections to extrapolate the measurements to the full kinematic range are provided. Next-to-next-to-leading-order QCD predictions provide a significantly better description of the results than next-to-leading-order QCD calculations, unless the latter are matched to a parton shower calculation.

title: "Table 1" of "Spin alignment and violation of the OZI rule in exclusive $\omega$ and $\phi$ production in pp collisions"

description: CERN-SPS. Exclusive production of the isoscalar vector mesons OMEGA and PHI is measured with a 190 GeV proton beam impinging on a liquid hydrogen target. The results presented here are obtained by selecting OMEGA and PHI mesons from the reactions P P --&gt; P P OMEGA, OMEGA --&gt; PI+ PI- PI0 and P P --&gt; P P PHI, PHI --&gt; K+ K-. The data were taken in 2008 and 2009 by the COMPASS experiment and correspond to an integrated luminosity of about 0.9 pb^{-1}. 

Cross section ratios are determined in three intervals of the Feynman variable XF of the fast proton. Its kinematic dependence on XF and on the invariant mass M(PV) of the system formed by the fast proton P(FAST) and vector meson V is presented. The cross section ratio is given by R(PHI/OMEGA) = (DSIG(P P --&gt; P P PHI)/DXF) / (DSIG(P P --&gt; P P OMEGA)/DXF). The OZI rule violation factor is also presented and is given by F(OZI) = R(PHI/OMEGA) / (TAN(DELTA(V)))**2 with (TAN(DELTA(V)))**2 being the OZI prediction. 

The measurement of the spin density matrix element RHO(00) of the vector mesons in different selected reference frames provides another handle to distinguish the contributions of these two major reaction types. Again, dependences of the alignment on XF and on M(PV) are presented.
