Experiments into solar neutrinos finds a surprising deficit in the number produced.
For every particle except the neutrinos there is an antiparticle of the opposite handedness.
In the process of fusing hydrogen to form helium, the nuclear reactions also produce elementary particles called neutrinos.
Indeed, dedicated neutrino detectors struggle just to record a handful of incoming neutrino detectors struggle just to record a handful of incoming neutrinos from potent nearby sources like the sun.
Leptons A family of particles consisting of the electron,the muon and the tau, along with their neutrinos.
One chapter provides a self-contained introduction to weak interaction phenomenology, including massive neutrinos of both Dirac and Majorana type.
Remember that the tau decays to produce two neutrinos in addition to the muon.
The fusion processes at the heart of Sun emit neutrinos of the electron variety.
