Claims

C1strongest claim

The perturbative contribution to the correlator of two heavy-light quark currents in HQET expanded in light-quark masses up to quadratic terms is calculated at the leading order in 1/β₀.

C2weakest assumption

That the leading 1/β₀ term faithfully approximates the full perturbative series for the Wilson coefficients of this particular correlator once the light-quark mass expansion is performed.

C3one line summary

Perturbative HQET correlator of heavy-light currents computed to O(m_q²) at leading 1/β₀ order with explicit renormalon-pole locations.
