Podcaster's summary: 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 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.

Cosmic Rays : Part 4 : Paleoclimatology and Muons
When ice forms it traps air molecules with it. Ancient ice, trapped deep in glaciers near the Earth's poles can give us a record of what the atmosphere was like thousands - if not millions - of years ago. But only if we can calibrate the relationship between time and depth. Unlike sunlight, muons from cosmic rays can penetrate deep into this glacial ice, complicating this just a little bit.

The Charged Sigma Baryons
The Sigma Baryons - that’s a capital Sigma - are a trio of slightly heavy cousins to everyday particles like the proton and the neutron. With masses of almost 1200 MeV each, it may surprise you that the physics of Sigma baryons feels much closer to a comparatively puny trio of pions. The similarities are helpful for building an intuition, but the differences are stark. While the charged pions are antiparticle partners, the charged Sigmas are anything but.

Quarks make up baryons like the proton and the neutron. Or more exotic things like the Lambda0 or the Delta++.

The Z Boson
Every once in a while, without warning, an electron is accelerated seemingly out of nowhere. Ripped from whatever atom, molecule or metal it had been associated with, it suddenly becomes it’s own ballistic particle. When this happens, a Z-boson has almost certainly been involved.

The Gluon
The strong nuclear force - the fundamental force behind the subnuclear junk we find inside the nucleons - is communicated via a particle very similar to the photon. But you’ll have to excuse their name, however apt. The particles that communicate between quarks are called gluons. Yes, as in glue.
2021-Oct-04 • 5 minutes
The Delta Baryons
The Delta baryons are combinations of up and down quarks. They’re like the proton and the neutron, only much more heavy and much less stable. They all seem to have about the same mass - around 1232 MeV, but we don’t really have a good handle on it. That is mostly because the Delta baryons lives are so short. They decay extremely quickly, in 5.6 ×10^−24 seconds.

The Neutron
With a mass of 939.565 MeV, the neutron is the second lightest baryon - that is, a particle made up of three quarks. The neutron's quarks include one up and two downs, so it is total electric charge is zero. The neutron may be electrically neutral, but don’t let that fool you, it still interacts with the electromagnetic field.
2021-Sep-30 • 3 minutes
The Proton
With a mass of 938.27 MeV, the proton is the lowest energy configuration of a trio of quarks. It has two up quarks and a down, but remember most of that mass is made up of subnuclear goo. You can find protons literally everywhere: from the nuclei of atoms on Earth to collisions at ultra high speeds from deep in outer space.

The Muon
Muons are a lesser known species of elementary particles that are extremely common, at least on Earth. They’re falling all around us, all the time. Muons are created by the collision of particles from outer space smashing into the molecules of the upper atmosphere.
2021-Sep-25 • 2 minutes
The Electron
The electron is arguably the most famous of the elementary particles. They are the business end of the atom, and their dynamics give rise to virtually all of chemistry. They’re also the basic working particle of electricity, and their presence or absence in the silicon transistors correspond to the digital 0’s or 1’s of modern computers.
2021-Sep-24 • 4 minutes
The Photon
Light is made up of particles: quirky, counterintuitive particles, but particles nonetheless. This fact was a surprise, and is still difficult to internalize, because light is also made up of electromagnetic waves. We call particles of light photons. Photons have no mass, but they do have energy.
2021-Sep-23 • 5 minutes
The Electron Cloud
Atoms are modeled by a nucleus surrounded by an electron cloud. We’ve discussed the nucleus earlier; it’s the hard center of the atom. It’s really, really small, as small as a speck of dust in the middle of a baseball stadium. Despite that fact, the nucleus makes up over 99% of the atom’s mass. Electrons are quite light by comparison.
2021-Sep-22 • 4 minutes
The Atomic Nucleus
We are made of molecules, and molecules are made of atoms, and atoms are really, really small. Atoms are so small that its hard for our minds to comprehend it, but if you need a reference point take your height and divide it by a billion. Or maybe ten billion! Atoms are too small to rationalize.

The Guide to the Field Guide to Particle Physics
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. Before we begin, we’ll visit some of the most important ideas in understanding particle physics, just to make sure we’re all on the same page.
