Measurement of the Υ (1S) production cross-section in pp collisions at √ s = 7 TeV in ATLAS

Abstract

A measurement of the cross-section for Υ (1S)→μ+μ− 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 Υ (1S) transverse momentum in two bins of rapidity,
