Astroparticle Physics and Colliders
In this talk I discuss the interplay between collider physics and four topics of astro– particle physics: neutrino oscillations, electroweak baryogenesis, LSP Dark Matter, and ultra–high energy cosmic rays (UHECR). Some astrophysical scenarios can (only) be tested decisively at colliders. In other cases input from collider experiments is required to sharpen predictions for future astro–particle...
متن کاملHigh Energy Astroparticle Physics
We give a brief (and highly incomplete) overview of the current experimental and theoretical status of high energy cosmic rays and their secondary γ−rays and neutrinos. We focus on the role of large scale magnetic fields and on multi-messenger aspects linking these three channels. We also recall that the flavor composition of neutrino fluxes from astrophysical sources contains information on bo...
متن کاملAstroparticle Physics with Ams02
The Alpha Magnetic Spectrometer (AMS02) experiment will be installed in 2009 on the International Space Station (ISS) for an operational period of at least three years. The purpose of AMS02 experiment is to perform accurate, high statistics, long duration measurements in space of charged cosmic rays in rigidity range from 1 GV to 3 TV and of high energy photons up to few hundred of GeV. In this...
متن کاملNeutrinos in astroparticle physics
I briefly discuss the role of neutrinos as probes in astroparticle physics and review the status of neutrino oscillation parameters as of June 2006, including recent fluxes, and latest SNO, K2K and MINOS results. I comment on the origin of neutrino masses in seesaw-type and low-scale models and mention some of their experimental signals.
متن کاملNeutrino Masses in Astroparticle Physics
The case for small neutrino mass differences from atmospheric and solar neutrino oscillation experiments has become compelling, but leaves the overall neutrino mass scale mν undetermined. The most restrictive limit of mν < 0.8 eV arises from the 2dF galaxy redshift survey in conjunction with the standard theory of cosmological structure formation. A relation between the hot dark matter fraction...
