Title: Asymmetries in tt¯ production: LHC versus Tevatron
Authors: Aguilar-Saavedra, Juan Antonio
Pérez-Victoria, Manuel
Issue Date: 2011
Abstract: The measurement of a charge asymmetry in tt¯ production at the LHC constitutes more than an independent confirmation of the forward-backward asymmetry found at the Tevatron. Indeed, both measurements together can be used to identify the source of the asymmetry. This is demonstrated for the case of new Z′, W′ vector bosons and color-sextet and triplet scalars, exchanged in t, u channels, respectively, and a very heavy axigluon in the s channel. In particular, current LHC measurements disfavor Z′, W′ models above the 2σ level.
