SUMMARY

The discussion centers on the size and classification of fundamental particles, specifically quarks and electrons. Participants clarify that quarks, such as up and down quarks, are considered fundamental components of matter, while electrons are classified as leptons and are also fundamental particles. The Standard Model of particle physics treats both quarks and leptons as pointlike entities, indicating that there are no known particles smaller than quarks. The conversation emphasizes the distinction between these particle types and their roles in the universe.

PREREQUISITES
  • Understanding of the Standard Model of particle physics
  • Familiarity with fundamental particles, specifically quarks and leptons
  • Basic knowledge of particle classification and interactions
  • Awareness of scientific terminology related to particle physics
NEXT STEPS
  • Research the Standard Model of particle physics in detail
  • Learn about the properties and classifications of leptons and quarks
  • Explore the concept of pointlike particles in quantum physics
  • Investigate current theories on particles smaller than quarks, if any
USEFUL FOR

Students of physics, researchers in particle physics, and anyone interested in the fundamental building blocks of the universe will benefit from this discussion.

i was just wondering if there's anything smaller than a quark because as far as i know up, down, anti-, etc. quarks make up the universe.

so electrons are smaller than quarks. i think. maybe i misread it
 
I believe the Standard Model currently treats both quarks and leptons as pointlike.

This should be moved to the Particles section.
 
What exactly is a quark??

What exactly is a quark??
 
An electron is a fundamental particle. There are no quarks associated. At least, that's my understanding.
