Neutrinos from the supernova

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 →

Magnetic horn, narrowing beam of muon neutrinos

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 →

How did the Standard Model of electroweak interactions win the trust?

Bubbles indicate a trace of an electron after emission of a neutral intermediate boson

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 →

Neutrinos appear in the beta decay of neutrons in nuclei

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 →

How do ‘accidental’ discoveries happen in physics?

Neutrinos from the explosion of an old star -- a supernova

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 →
