Summary
Within the QCD jet calculus formalism, we deduce an equation describing recombination of quarks and antiquarks into mesons within a quark or gluon jet. This equation relates the recombination function R(x/sub 1/,x/sub 2/,x) used in current literature to the fragmentation function for producing that same meson out of the parton initiating the jet. We submit currently used recombination functions to our consistency test, taking as input mainly the u-quark fragmentation data into ..pi../sup +/ mesons, but also s-quark fragmentation into K/sup -/ mesons. The constraint is well satisfied at large Q/sup 2/ for large moments. Our results depend on one parameter, Q/sub 0//sup 2/, the constraint equation being satisfied for small values of this parameter.
