Seesaw Majoron Model of Neutrino Mass and Novel Signals in Higgs Boson Production at LEP
Marco A. Diaz, M. A. Garcia-Jareno, Diego A. Restrepo +1
We perform a careful study of the neutral scalar sector of a model which includes a singlet, a doublet, and a triplet scalar field under . This model is motivated by neutrin…
Gluino Cascade Decays With Broken R--Parity
A. Bartl, F. de Campos, M. A. Garcia-Jareno +4
We study the pattern of gluino cascade decays in a class of supersymmetric models where R-parity is spontaneously broken. The multi-lepton and same-sign dilepton rates in these mod…
Neutrino Mass and Missing Momentum Higgs Boson Signals
M. A. Diaz, M. A. Garcia-Jareno, D. A. Restrepo +1
In the simplest scheme for neutrino masses invoking a triplet of Higgs scalars there are two CP-even neutral Higgs bosons (i=1,2) and one massive pseudoscalar . For some c…
R--Parity Violating Signals for Chargino Production at LEP II
F. de Campos, O. J. P. Eboli, M. A. Garcia-Jareno +1
We study chargino pair production at LEP II in supersymmetric models with spontaneously broken R-parity. We perform signal and background analyses, showing that a large region of t…
Charged Higgs Boson and Stau Phenomenology in the Simplest R-Parity Breaking Model
A. Akeroyd, Marco A. Diaz, J. Ferrandis +2
We consider the charged scalar boson phenomenology in the simplest effective low-energy R-parity breaking model characterized by a bilinear violation of R-parity in the superpotent…
Signatures of Spontaneous Breaking of R-Parity in Gluino Cascade Decays at LHC
A. Bartl, W. Porod, F. de Campos +4
We study the pattern of gluino cascade decays in a class of supersymmetric models where R-parity is spontaneously broken. We give a detailed discussion of the R-parity violating de…
New Signatures for a Light Stop at LEP2 in SUSY Models with Spontaneously Broken R-Parity
A. Bartl, W. Porod, M. A. Garcia-Jareno +3
In a class of supersymmetric models with R-parity breaking the lightest stop can have new decay modes into third generation fermions, . We show that…
LEP Sensitivities to Spontaneous R-Parity Violating Signals
J. C. Romao, F. de Campos, M. A. Garcia-Jareno +2
We illustrate the sensitivities of LEP experiments to leptonic signals associated to models where supersymmetry (SUSY) is realized with spontaneous breaking of R-parity. We focus o…
Novel Scalar Boson Decays in SUSY with Broken R-Parity
F. de Campos, M. A. Garcia-Jareno, Anjan S. Joshipura +2
R parity violation can induce mixing of the supersymmetric Higgs bosons with the sneutrinos at the tree level. We study the effect of this mixing on the decays of Higgs scalars as…
Limits on Associated Production of Visibly and Invisibly Decaying Higgs Bosons from Z Decays
F. De Campos, M. A. Garcia-JareÑO, Anjan S. Joshipura +3
Many extensions of the standard electroweak model Higgs sector suggest that the main Higgs decay channel is "invisible", for example, where denotes the majoron, a w…
