Measurement of the Y(1S) production cross-section in pp collisions at root s=7 TeV in ATLAS
Original language description
A measurement of the cross-section for Y(1S) -- mu(+)mu(-) production in proton-proton collisions at centre of mass energy of 7 TeV is presented. The cross-section is measured as a function of the Y(1S) transverse momentum in two bins of rapidity. The measurement requires that both muons have transverse momentum p_T(mu) great then 4 GeV and pseudorapidity less then 2.5 to reduce theoretical uncertainties on the acceptance, which depend on the poorly known polarisation. The results are based on an integrated luminosity of 1.13 pb^(-1), collected with the ATLAS detector at the Large Hadron Collider at CERN. The cross-section measurement is compared to theoretical predictions: it agrees to within a factor of two with a prediction based on the NRQCD modelincluding colour-singlet and colour-octet matrix elements as implemented in PYTHIA while it disagrees by up to a factor of ten with the next-to-leading order prediction based on the colour-singlet model.
