Abstract
We calculate the multiplicity of heavy quark pairs in gluon jets in lowest order QCD, along with the non-perturbative correction related to the gluon condensate 〈(α/π)F2〉. The value of the non-perturbative correction is A figure is presented where M is the mass of the heavy quark, N is the number of colors, and CF and CA are the values of the Casimir operators in the fundamental and adjoint representation respectively. α(M) is the running coupling constant at the scale of the heavy quark, and 〈F2〉 is the gluon condensate, usually determined to be 〈α/πF2〉 ∼ 0.012 GeV4. The non-perturbative correction is extremely small
