Heavy flavour results from ATLAS

TL;DR

This paper presents ATLAS experiment results on heavy-flavour production, including cross-sections, quarkonium states, D-mesons, and B-hadron lifetimes, based on 2010 proton-proton collision data at the LHC.

Contribution

It provides new measurements of heavy-flavour production and lifetimes, comparing experimental data with theoretical models for the first time in this context.

Findings

Measured differential cross-sections for heavy-flavour production

Compared quarkonium and D-meson yields to theoretical predictions

Reported B-hadron lifetime measurements

Abstract

A selection of heavy-flavour physics results from the ATLAS experiment is presented, based on data collected in proton-proton collisions at the LHC during 2010. Differential cross-sections for the production of heavy flavours, charmonium and bottomonium states and D-mesons are presented and compared to various theoretical models. Results of B-hadron lifetime measurements are also reported.
