By Stephen BeechA “forgotten” particle could answer the mystery of why we exist, say physicists. A new theory on the birth of the cosmos has been unveiled, suggesting the early universe was shaped by an ancient particle that has been overlooked for decades. The research, published in the journal Physical Review Letters, tackles one of the greatest conundrums in modern physics — how matter triumphed over antimatter in the aftermath of the “Big Bang”. According to current theories, both should have annihilated each other after a colossal explosion — leaving nothing but an empty universe of pure energy. But physicists at the University of Southampton and the Indian Institute of Technology Kanpur say they found a clue in a neutrino, one of the lightest particles in the universe. The research team discovered that an often-ignored relative of the particles — known as a “decoupled” heavy neutrino — could have helped matter dominate over its counterpart.
