The Nobel Prize for Physics in Takaaki Kajita and Arthur B. McDonald – ANSA.it

The Nobel Prize in Physics 2015 was awarded to Japanese Takaaki Kajita and Canadian Arthur B. McDonald for discoveries concerning the most elusive particles of the universe, the neutrinos, and that allowed for the first time to establish that neutrinos have mass. Takaaki Kajita discovered that neutrinos in the atmosphere changed identity in the experiment Super-Kamiokande, University Tokyi. Meanwhile, in Canada, Arthur B. McDonald showed that neutrinos coming from the Sun does not disappear in the path towards the Earth, but took on a different identity with the Sudbury Neutrino Observatory experiment Collaboration

Witnesses the ‘metamorphosis’ neutrinos

Takaaki Kajita and Arthur B. McDonald gave a key contribution to the understanding of ‘metaformofosi’ neutrino. And ‘the process by which each of the three types of neutrinos exist in nature can change its identity, assuming that one of the other’ members’ of the family. For the Nobel Committee findings open the way for a new image of the universe.

Who are Kajita and Campbell
The Japanese Takaaki Kajita, 56, born in 1959 in Higashimatsuyama and has always worked in the University of Tokyo, where he heads the Institute for research on cosmic rays. Arthur B. McDonald, 76, was born in 1943 in Sydney, Canada. He studied in Californa Institute of Technology (Caltech) and is now professor emeritus of the Canadian Queen’s University.

Neutrinos, light on the mysteries of the ‘universe
It’ deserved the Nobel Prize in Physics 2015 awarded to research on neutrinos: the president dell’dell’Istituto National Nuclear Physics (INFN), Fernando Ferroni, ” this mysterious particles are structurally different from all other particles that we know and might be the door on a new physics ”. Neutrinos, with their bizarre behavior closely studied in Italy, may help you understand the most mysterious aspects of the universe.

Kajita and McDonald played a leading role in demonstrating the ability of neutrinos change from one type to another and thus have a bulk . ” With this – noted Ferroni – Kajita and McDonald have unearthed the only flaw of the Standard Model ”, the reference theory of contemporary physics to the effect that neutrinos have no mass.
The two Nobel have therefore established a milestone in the history of research on neutrinos. The transformations of these particles were observed subsequently in many other experiments. Among these ‘ Opera ‘ and ‘ BOREXINO ‘, that have been conducted in Italy, in the National Laboratories of Gran Sasso INFN. ” Italy – said Ferroni – is well represented in the history of the neutrinos ”.

To make it even more compelling and complex history of research on neutrinos there is also the assumption made by most mysterious boys Panisperna, Ettore Majorana . The hypothesis holds that the neutrino and its corresponding nell’antimateria (the antineutrino) would be the same particle. The world is divided into physical connection because according to some neutrino and antineutrino would rather two distinct particles. The final answer may come from Italy, with the experiment ‘ Heart ‘ being in the laboratories at Gran Sasso.
