New findings that reveal why the universe is dominated by matter and why we exist will be presented by the international T2K Collaboration, a team a researchers who will demonstrate why matter and antimatter are different.
Stony Brook University physicist Professor Chang Kee Jung, a leading member of the T2K Collaboration, will present the results of the T2K findings and explain why they are significant to theories of particle physics and Bing Bang Cosmology.
According to Prof. Jung, T2K’s recent finding hints that neutrinos and antineutrinos may oscillate slightly differently, which is a break of fundamental symmetry (Charge-Parity) in physics.
“Physicists believe that this is deeply related to the question of why our current universe is dominated by matter and why we exist,” he says. “At the onset of the Big Bang, the universe must have been symmetric, i.e. there existed the same amount of matter and antimatter. Charge-Parity violation could allow very heavy neutral particles to decay to neutrinos at a slightly higher rate than to antineutrinos which created the initial imbalance in the amount of matter and antimatter. Without this process, we would not exist, and our universe today would instead contain only light and energy resulting from the inevitable matter-antimatter annihilation after the Big Bang.
“T2K’s finding is by no means a definitive discovery. Rather it is perhaps the first significant step toward the elucidation of a matter dominant universe, for which much more data and many more years of effort is needed.”
