November General Meeting

Dr. Helen Quinn

Rob Hawley


When scientists first discovered antimatter it appeared to be identical to regular matter. Same charges, same forces. It was just like looking in a mirror. A high energy photon (which were copiously produced during the big bang) produces equal amounts of matter and antimatter. And yet there is no detectable antimatter in the universe today. Where did it go? Maybe antimatter and matter are not true mirror images of each other.

During the General Meeting on November 8, Dr. Helen Quinn will talk about the search to find out if matter and antimatter are really identical (they are not) and what effect is large enough to explain why all the antimatter disappeared.

Dr. Quinn is a professor of Physics at Stanford Linear Accelerator at Stanford. She is co-author of the book “The Mystery of the Missing Antimatter”.
