Up Quark Structure

Spin eDP: Helical Motion

• Central +qCP: Base charge +1. Forms the quark core.
• Spin eDP: Helical orbit providing 1/2 h-bar spin. Inner +eCP oscillates radially while circling, outer -eCP maintains stable orbit.
• No Extra hDP: Up-type quarks have only the spin eDP, no additional hybrid dipole pair.
• Effective Charge: The -eCP partially shields the +qCP, reducing +1 base to +2/3 effective charge.

Charge Shielding Mechanism

The central +qCP has a base charge of +1. The spin eDP's outer -eCP (base charge -1) provides partial shielding through its orbital motion. The time-averaged effect reduces the observable charge to +2/3 e. This is the lightest quark, with minimal structure beyond the bare core and spin mechanism.
