b-Production measurements with ATLAS

The Large Hadron Collider at CERN will produce b-hadrons with unprecedented ly high statistics, and with a higher energy reach than any previous machin e. The ATLAS detector will offer excellent acceptance and performance for b physics studies and will make high statistics measurements of b-quark prod uction to probe QCD. ATLAS can contribute to an understanding of the large discrepancy seen between the QCD prediction and Tevatron cross-section meas urements. Measurements will be made of the absolute and differential produc tion cross-sections. Measurements of bb correlations will be made to test t he NLO contributions to the cross-section and to place limits on non-pertur bative effects, (C) 2001 Published by Elsevier Science B.V.
