کوارک پایین

I don't have sufficient context provided to write an accurate 2-sentence overview. The context given only states "down type of quark" without details about what down quarks are, their properties, or their significance. To provide an accurate overview for a general reader, I would need additional source material describing down quarks' characteristics, role in particle physics, or why they're scientifically important.
