We postulate a supplemental power counting within the heavy quark effective theory, that results in a small, highly-constrained set of second-order power corrections, compared to the standard approach. We determine all B̄ → D(∗) form factors, both within and beyond the standard model to O(αs/mc,b, 1/mc,b), under truncation by this power counting. We show that the second-order power corrections to the zero-recoil normalization of the B̄ → D(∗)lν matrix elements (l = e, μ, τ) are fully determined…

The xishacorene natural products are structurally unique apolar diterpenoids that feature a bicyclo[3.3.1] framework. These secondary metabolites likely arise from the well-studied, structurally
