Search for light custodians in a clean decay channel at the LHC
H. de Sandes, R. Rosenfeld
Models of warped extra dimensions with custodial symmetry usually predict the existence of a light Kaluza-Klein fermion arising as a partner of the right-handed top quark, sometime…
A new signature for color octet pseudoscalars at the LHC
Alfonso R. Zerwekh, Claudio O. Dib, Rogerio Rosenfeld
Color octet (pseudo)scalars, if they exist, will be copiously produced at the CERN Large Hadron Collider (LHC). However, their detection can become a very challenging task. In part…
The Higgs portal and an unified model for dark energy and dark matter
O. Bertolami, R. Rosenfeld
We examine a scenario where the Higgs boson is coupled to an additional singlet scalar field which we identify with a quintessence field. We show that this results in an unified pi…
Higgs Pair Production at the LHC in Models with Universal Extra Dimensions
Hiroshi de Sandes, Rogerio Rosenfeld
In this letter we study the process of gluon fusion into a pair of Higgs bosons in a model with one universal extra dimension. We find that the contributions from the extra top qua…
Technicolor contribution to lepton + photon + missing energy events at the Tevatron
A. R. Zerwekh, C. O. Dib, R. Rosenfeld
Events with one lepton, one photon and missing energy are the subject of recent searches at the Fermilab Tevatron. We compute possible contributions to these type of events from th…
Constraints on a scalar-pseudoscalar Higgs mixing at future e+e- colliders: an update
A. Chalov, A. Likhoded, R. Rosenfeld
We perform an update of our previous analysis on the constraints on possible deviations of Hbb coupling from its Standard Model value, arising from a scalar-pseudoscalar mixing. In…
