José W. F. Valle
Encyclopedia
José W. F. Valle is a Brazilian-Spanish physicist whose research includes many aspects of astroparticle physics
and high energy physics, especially neutrino
physics.
He is a senior scientist at the Spanish Council for Scientific Research CSIC
, the largest public research body in Spain, leading both the Astroparticle and High Energy Group (AHEP group) and the Theory Division of IFIC (Instituto de Física Corpuscular
) at the University of Valencia.
He has contributed to the modern theory of neutrino mass and neutrino oscillation
whose recent experimental discovery was a triumph of neutrino astronomy
, an emerging field which has given the physics Nobel Prize
in 2002 to Raymond Davis Jr.
and Masatoshi Koshiba
. This discovery provides the only firm indication of the incompleteness of the Standard Model
of particle physics with important consequences also for astrophysics
and cosmology
.

Neutrino
A neutrino is an electrically neutral, weakly interacting elementary subatomic particle with a half-integer spin, chirality and a disputed but small non-zero mass. It is able to pass through ordinary matter almost unaffected...

Neutrino oscillation
Neutrino oscillation is a quantum mechanical phenomenon predicted by Bruno Pontecorvowhereby a neutrino created with a specific lepton flavor can later be measured to have a different flavor. The probability of measuring a particular flavor for a neutrino varies periodically as it propagates...

Neutrino astronomy
Neutrino astronomy is the branch of astronomy that observes astronomical objects with neutrino detectors in special observatories. Nuclear reactions in stars and supernova explosions produce very large numbers of neutrinos, a very few of which may be detected by a neutrino telescope...
