Definition of Anti-quark charge reversal
Check what you remember
Read the wording for your board, then hide it and explain Anti-quark charge reversal in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Anti-quarks carry opposite charge to their corresponding quarks, so anti-up has −2/3 e, anti-down has +1/3 e and anti-strange has +1/3 e.
