They’re just part of life. The <a href="https://pasayten.org/the-field-guide-to-particle-physics/electron">electron</a> has its <a href="https://pasayten.org/the-field-guide-to-particle-physics/positron">positron</a> partner. <a href="https://pasayten.org/the-field-guide-to-particle-physics/muon">Muons and antimuons</a> are both <a href="https://share.transistor.fm/s/f3e355a9">routinely created in the upper atmosphere</a>.  They’re so familiar that we often just call them mu plus or mu minus. The antiparticle nature of mu plus just isn’t that big a deal.</p><p>If you’ve been paying attention to our series, you know we’ve talked about antiparticles quite a bit, at least in passing. <a href="https://pasayten.org/the-field-guide-to-particle-physics/up-and-down-quarks">Up and down quarks</a> sometimes associate with anti-up and anti-down quarks to form <a href="https://pasayten.org/the-field-guide-to-particle-physics/charged-pion">pions</a>. Other mesons like <a href="https://pasayten.org/the-field-guide-to-particle-physics/neutral-kaons">kaons</a> form similar quark-antiquark pairs.</p><p>It’s fun to see composite particles made up from particles and antiparticles.
