Invisible Higgs Boson Decays in Spontaneously Broken R-Parity


Prof. Jorge Romão

Abstract

The Higgs boson may decay mainly to an invisible mode characterized by missing energy, instead of the Standard Model channels. This is a generic feature of many models where neutrino masses arise from the spontaneous breaking of ungauged lepton number at relatively low scales, such as spontaneously broken R-parity models. Taking these models as framework, we reanalyze this striking suggestion in view
of the recent data on neutrino oscillations that indicate non-zero neutrino masses. We show that, despite the smallness of neutrino masses, the Higgs boson can decay mainly to the invisible Goldstone boson associated to the spontaneous breaking of lepton number.
The search for invisibly decaying Higgs bosons should be taken into account in the planning of future accelerators,
such as the Large Hadron Collider and the Next Linear Collider.

Reconstruction of Supersymmetric High Scale Theories


Dr. Werner Porod

Physik-Institut (Universitaet Zuerich)

Seminari del IFIC

Friday, January 17th, 2003 at 12:00

Abstract

We demonstrate how the fundamental supersymmetric theory at high energy scales can be reconstructed using precision data expected at future high energy collider experiments. We have studied a set of representative examples in this context: minimal supergravity; gauge mediated supersymmetry breaking; and superstring effective field theories.

Neutrinos and Ultra-High Energy Cosmic Rays


Dr. Dmitry V. Semikoz

Max-Planck-Institut für Physik, Munich

Sala Seminarios IFIC (Edf. Institutos Paterna)

Tuesday, October 22nd, 2002 at 12:30

Abstract

In this talk I will discuss both neutrinos directly coming from astrophysical sources and neutrinos produced by ultra-high energy (UHE) protons in interactions with the cosmic microwave background radiation. I will also consider possible neutrino fluxes in several exotic UHE cosmic ray models and fluxes from individual sources. I will show that in a variety of cases the diffuse neutrino flux can be considerably higher than the earlier theoretical estimates. High neutrino fluxes would significantly increase the chances to detect UHE neutrinos with experiments currently under construction or in the proposal stage.
