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.
Highlights
The goals of the heavy-flavour physics programme at ATLAS are to test theoretical models for heavy-flavour production within the Standard Model (SM) and to search for new physics through rare decays or new sources of CP violation
The sub-detectors of greatest importance to the analyses presented here are in the Inner Detector (ID) tracker and Muon Spectrometer (MS) systems
In many cases the data collection has relied on specific B-physics trigger selections implemented in the Higher Level Trigger (HLT)
Summary
The goals of the heavy-flavour physics programme at ATLAS are to test theoretical models for heavy-flavour production within the Standard Model (SM) and to search for new physics through rare decays or new sources of CP violation. These proceedings present a non-exhaustive selection of analyses completed during 2011 based on 2010 data, divided into cross-section measurements (Section 2) and lifetime measurements (Section 3). In many cases the data collection has relied on specific B-physics trigger selections implemented in the Higher Level Trigger (HLT)
