چکیده

Neutrinos can play an important role in the evolution of the Universe, modifying some of the cosmological observables. We describe how the precision of present cosmological data can be used to learn about neutrino properties, in particular their mass. Cosmology can provide information on the absolute scale of neutrino masses, complementary to the results of tritium beta decay and neutrinoless double beta decay experiments. We show how the analysis of current cosmological observations provides an upper bound on the sum of neutrino masses, with improved sensitivity from future cosmological measurements well into the sub-eV range.

The Homi Bhabha Lecture Neutrino Physics and Astrophysics

Neutrinos are very elusive particles. Having only weak (and gravitational) interactions they are extremely difficult to detect, but their study has been always extremely rewarding, both for physics and (more recently) astrophysics. In the last several years the progress in neutrino physics has been impressive leading to the discovery, for the first time, of physics of elementary particle phenom...

Neutrino Astrophysics at the Cross Roads

The indications for neutrino oscillations from the atmospheric and solar neutrino anomalies and from the LSND experiment are now so overwhelming that the discourse in neutrino physics has changed. One no longer asks if these particles indeed oscillate, one rather debates the most plausible pattern of masses and mixing angles, and if the existence of a sterile neutrino is required. Of course, al...

What Do Solar Models Tell Us about Solar Neutrino Experiments?

If the published event rates of the chlorine and Kamiokande solar neutrino experiments are correct, then the energy spectrum of neutrinos produced by the decay of B in the sun must be different from the energy spectrum determined from laboratory nuclear physics measurements. This change in the energy spectrum requires physics beyond the standard electroweak model. In addition, the GALLEX and SA...

Theoretical Issues in Neutrino Physics

In this talk I would like to discuss a number of the open questions we have entertained about neutrinos since they were first postulated more than 65 years ago, as well as a few of the possible answers that may result from atmospheric, solar, and terrestrial neutrino experiments. Indeed, the list of open questions has proven surprisingly resistant to experiment: • What are the masses of the νe,...
