Asymmetries in tt¯ production: LHC versus Tevatron Aguilar Saavedra, Juan Antonio Pérez-Victoria, Manuel Asymmetry LHC (Large Hadron Collider) Tevatron Top quark Hadron colliders 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. 2014-02-25T11:20:54Z 2014-02-25T11:20:54Z 2011 info:eu-repo/semantics/article Aguilar-Saavedra, J.A.; Pérez-Victoria, M.
