Shaping the top asymmetry Aguilar Saavedra, Juan Antonio Pérez-Victoria, Manuel Top quark Forward-backward (FB) Asymmetry Tevatron We study different profiles of the distribution of the top forward-backward asymmetry, depending on the invariant mass of the t tbar pair. We show that they can be reproduced by one or more light colour octets, while keeping moderate departures of the t tbar cross section and invariant mass distributions with respect to the Standard Model predictions at Tevatron and LHC. 2014-02-24T13:01:51Z 2014-02-24T13:01:51Z 2011 info:eu-repo/semantics/article Aguilar-Saavedra, J.A.; Pérez-Vitoria, M.
