Gluon excitations in t tbar production at hadron colliders

Roberto Barcelo, Adrian Carmona, Manuel Masip +1

We argue that a relatively light massive gluon with mass <= 1 TeV, small purely axial couplings to light quarks and sizable vector and axial couplings to the top quark can reproduc…

Constraints on the Wtb vertex from early LHC data

J. A. Aguilar-Saavedra, N. F. Castro, A. Onofre

We use the recent measurements of top quark decay asymmetries in ATLAS and the t-channel single top cross section in CMS to set the first combined LHC limits on the Wtb vertex. Thi…

Scalar and pseudoscalar Higgs production in association with a top-antitop pair

Rikkert Frederix, Stefano Frixione, Valentin Hirschi +3

We present the calculation of scalar and pseudoscalar Higgs production in association with a top-antitop pair to the next-to-leading order (NLO) accuracy in QCD, interfaced with pa…

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…

Probing the Tevatron t tbar asymmetry at LHC

J. A. Aguilar-Saavedra, M. Perez-Victoria

We use an effective operator framework to study the contributions to the Tevatron t tbar asymmetry from arbitrary vector bosons and scalars, and compare with their effect on the t…

Lepton flavor violation in the Simplest Little Higgs model

F. del Aguila, J. I. Illana, M. D. Jenkins

The flavor sector of Little Higgs models based on product groups, notably the Littlest Higgs with T parity (LHT), has been extensively studied and some amount of fine tuning was fo…
