Overview of models for the tt asymetry Aguilar Saavedra, Juan Antonio Top quark LHC (Large Hadron Collider) Standard model 4th International Workshop on Top Quark Physics, 25-30th September 2011, Sant Feliu de Guixols, Spain. We review the most popular models proposed to explain the anomalous forward-backward asymmetry in t tbar production at the Tevatron. We discuss their viability in view of recent LHC data. We summarise their predictions for charge asymmetries at the LHC. 2014-02-24T12:14:48Z 2014-02-24T12:14:48Z 2012 conference output arXiv:1202.2382v1 http://hdl.handle.net/10481/30529 eng http://creativecommons.org/licenses/by-nc-nd/3.0/ open access Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License
