Starting from the most general non-derivative four-baryon Lagrangians, we perform a systematic non-relativistic expansion of baryon bilinears up to next-to-leading order (NLO) in three-momentum, obtaining closed-form contact potentials for BB, BD, and DD channels through O(Q2). At this stage the theory contains 134 low-energy constants (LECs)—28 …
