The study, carried out by researchers at the University of Sao Paulo, Brazil, demonstrated the existence of symmetry between particles and antiparticles core, concerning their charge, parity and time.
The experiment was part of a broader study, in order to detect differences in the manner in which protons and neutrons in the nuclei are joined, with their antiparticles.
The antimatter have the same mass but opposite electric charge of the particles.
Marcelo Munoz, professor of Physics at the University of Sao Paulo, said:
“After the Big Bang, for every particle of matter an antiparticle was created. In Particle Physics, the crucial question is whether all the laws of physics exhibit a peculiar kind of symmetry known as CPT (charge, parity, time). These measurements show the existence of a fundamental symmetry between core and antinuclear.”
These measurements were made possible thanks to an experiment of ring Large Hadron Collider (LHC).
