Contribution
It introduces a novel calculation of the $ar{s}s$ condensate in heavy mesons using unquenched hopping parameter expansion at infinite coupling.
Findings
Quantitative estimate of the $ar{s}s$ condensate in D- and B-mesons.
Discussion of the phenomenological implications of the condensate value.
Abstract
We calculate the condensate in the D - and B - mesons using the unquenched hopping parameter expansion at infinite coupling for the Wilson lattice action. We discuss the phenomenological relevance of our result.
