Lifetime differences arise from spectator effects such as $W$-exchange and Pauli interference. The $\\Xi_{cc}^{++}$ baryon is longest-lived in the doubly charmed baryon system owing to the destructive Pauli interference absent in the $\\Xi_{cc}^+$ and $\\Omega_{cc}^+$. In the presence of dimension-7 contributions, its lifetime is reduced from $\\sim5.2\\times 10^{-13}s$ to $\\sim3.0\\times 10^{-13}s$.
