Z' Bosons and Friends
Manuel Perez-Victoria
The invariance of extensions of the Standard Model under the full SU(3)XSU(2)XU(1) gauge group can be used to classify general vector bosons and to write their interactions in a mo…
Shaping the top asymmetry
J. A. Aguilar-Saavedra, M. Perez-Victoria
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 on…
Simple models for the top asymmetry: constraints and predictions
J. A. Aguilar-Saavedra, M. Perez-Victoria
We perform a comprehensive study of the allowed range for the Tevatron t tbar forward-backward asymmetries in six representative new physics models: a flavour-changing Z' boson, a…
Asymmetries in t tbar production: LHC versus Tevatron
J. A. Aguilar-Saavedra, M. Perez-Victoria
The measurement of a charge asymmetry in t tbar production at LHC constitutes more than an independent confirmation of the forward-backward asymmetry found at Tevatron. Indeed, bot…
Impact of extra particles on indirect Z' limits
F. del Aguila, J. de Blas, P. Langacker +1
We study the possibility of relaxing the indirect limits on extra neutral vector bosons by their interplay with additional new particles. They can be systematically weakened, even…
No like-sign tops at Tevatron: Constraints on extended models and implications for the t tbar asymmetry
J. A. Aguilar-Saavedra, M. Perez-Victoria
We use a recent upper limit from CDF on like-sign top pair production to place constraints on general new vector bosons and scalars mediating u u -> t t. The possible vector bosons…
