The Field Guide to Particle Physics
The Field Guide to Particle Physics
Sean Downes
This is your informal guide to the subatomic ecosystem we’re all immersed in. In this series, we explore the taxa of particle species and how they interact with one another. Our aim is give us all a better foundation for understanding our place in the universe. The guide starts with a host of different particle species. We’ll talk about their masses, charges and interactions with other particles. We’ll talk about how they are created, how they decay, and what other particles they might be made of.
The Reason for Antiparticles
Antimatter is uncommon, but it’s not exactly rare. Antiparticles - especially those generated by cosmic radiation - are all around us, all the time. But just what is it doing here? As we discuss, the role of antimatter is fundamentally tied to our experience of reality.

Bonus: We should build a muon collider.
Particle Physics is a source of more than just fascinating questions. Today we give four important reasons why we should build another particle collider. Share these four reasons with someone, especially if they aren't bought in!

The Positron Excess
Searching for antimatter in the wild reveals a bit more than we expected. But only a bit. Are pulsars to blame? or is it Dark Matter?

The Antineutrino
Are there antineutrini out there? Yes, surely. But, a better question is what are antineutrini?

The Antineutron
Like the antiproton, the antineutron is a composite particle made up of antiquarks. It looks a lot like the neutron, and that’s pretty interesting because both of those particles have no electric charge!

The Antiproton
Virtual pions and gluons and other quantum effects are all dressed up in the antiproton package around three valance antiquarks. That’s two anti-up quarks and one anti-down quark. The antiproton looks virtually identical to the proton - except that it has a negative electric charge.

The Positron
The positron is the antiparticle partner to the electron. Like the electron, positrons are stable. They do not decay. But of course, we don’t see may of them around.
