  "abstract": "Chiral crystals provide a natural platform for unconventional topological fermions, while light-element carbon--boron frameworks are promising for phonon-mediated superconductivity owing to strong covalent bonding and high phonon frequencies. Here, we combine Wyckoff-position-based structure generation with high-throughput first-principles calculations to search for C--B crystals in selected hexagonal chiral space groups. Starting from 972 generated $\\mathrm{C}_m\\mathrm{B}_n$ structures ($m,n=1\\text{--}4$), successive filters based on energetic stability, dynamical stability, electronic metallicity, topological band features, and thermal stability identify six stable candidates: $(\\mathrm{C}_3\\mathrm{B}_2)_8$, $(\\mathrm{C}\\mathrm{B}_2)_3$, $(\\mathrm{C}\\mathrm{B}_4)_6$, $(\\mathrm{C}_3\\mathrm{B}_2)_6$, $(\\mathrm{C}_2\\mathrm{B}_3)_6$, and $(\\mathrm{C}\\mathrm{B}_2)_6$. These materials host diverse topological semimetal states near the Fermi level, including charge-one, charge-two, and charge-three Weyl points, nodal rings, and nodal-surface states. Notably, $(\\mathrm{C}_3\\mathrm{B}_2)_8$ exhibits screw-symmetry-protected charge-three Weyl points and strong electron--phonon coupling, yielding a McMillan transition temperature of $31.1\\,\\mathrm{K}$ for the Coulomb pseudopotential parameter $μ^* = 0.10$. In addition, $(\\mathrm{C}\\mathrm{B}_2)_3$ hosts multiple charge-one Weyl points and pronounced anisotropic multiband superconductivity revealed by fully anisotropic Eliashberg calculations. These results extend the materials scope of topological semimetals with phonon-mediated superconductivity to chemically designed chiral light-element structures.",
