But this does a poor job of explaining why matter triumphed over antimatter in the moments after the big bang.

Whether the hypothetical CP violation would fully explain matter's dominance over antimatter depends on the new physics that gave rise to it.

SLAC is involved in four neutrino experiments — EXO, DUNE, MicroBooNE and ICARUS — that want to shine light on the elusive particles, whose properties could be linked to cosmic evolution, invisible dark matter and matter's dominance over antimatter in the universe.

Further observations of this behaviour may shed light on how matter came to dominate over antimatter in the universe.

But why would nature favor matter over antimatter?

Physicists think that primordial processes produced a tiny excess of matter over antimatter.

Some hoped this oddity might end up offering clues to areas that the standard model is silent on, such as dark matter and why there is an excess of matter over antimatter in the universe.

To find out more about the elusive particles and their potential links to cosmic evolution, invisible dark matter and matter's dominance over antimatter in the universe, the Department of Energy's SLAC National Accelerator Laboratory is taking on key roles in four neutrino experiments: EXO, DUNE, MicroBooNE and ICARUS.

Other experiments have found evidence of CP symmetry violations in more exotic types of particles, such as kaons or B mesons, but they aren't enough by themselves to explain the dominance of matter over antimatter.

In the early universe, the differences might have created a preponderance of matter over antimatter that would account for the universe's current composition.

Any discrepancies between hydrogen and antihydrogen might help explain why matter won out over antimatter in our observable universe.

Yet our Universe is overwhelmingly made of matter, and so something long ago must have favoured matter over antimatter.

Work on so - called symmetry breaking helped to shape the Standard Model and explain why matter won out over antimatter

The standard model of particle theory successfully describes every fundamental particle and force observed in laboratories, yet fails to explain properties of the universe such as the existence of dark matter, the amount of dark energy, and the preponderance of matter over antimatter.

A non-zero charge would have meant that the antiproton in the nucleus and the positron buzzing around it have slightly different charges, which would violate the rules of the Standard Model of particle physics and possibly provide an explanation for the dominance of matter over antimatter in the universe.

Any discrepancies would provide insight into the physical processes that favor matter over antimatter.

The CP LEAR experiment is already collecting good quality data with antiprotons, hoping to understand the mechanism, known as charge - parity (CP) violation, which has lead to the domination of matter over antimatter in the Universe.
