Prior the recombination into atoms, the now visible matter of the universe consisted of electron-nucleus plasma. The nuclei in there were basically hydrogen (three fourth) and helium (one fourth). Their abundances were defined by the available number of protons … Continue reading
Conversion of the protons of star into neutrons with the emission of neutrinos So-called supernova explosion occurs as a result of gravitational collapse of a star, completing its life cycle, if its weight exceeds a few solar masses (the Chandrasekhar … Continue reading
About the countless muon neutrinos flying in a beam… The discovery of partons in nucleons and intermediate bosons involved in weak interactions has been made owing to the fact that at experimenters’ disposal in the 60s, there were high-energy beams … Continue reading
On one of the peaks of human thought in particle physics According to the model of weak interactions existed in the 60’s, that was based on the Fermi’s theory of beta decay, muon neutrinos interacting with matter are to turn … Continue reading
Departing together with electrons and carrying the invisible energy The discovery of neutrons, it seemed, has clarified the structure of matter. All elementary particles needed to build atoms were known. It only remained unclear where are the electrons observed in … Continue reading
Expecting antineutrinos from the sun, but getting them from a supernova After a huge amount of work carried out by scientists to find a coherent theoretical scheme or to create experimental unit, new knowledge comes as it were perfectly normal. … Continue reading
