We report the measurement of charged D[superscript *] mesons in inclusive jets produced in proton-proton collisions at a center-of-mass energy sqrt [s]=200 GeV with the STAR experiment at the Relativistic Heavy Ion Collider. For D[superscript *] mesons with fractional momenta 0.2<z<0.5 in inclusive jets with 11.5 GeV mean transverse energy, the production rate is found to be N(D[superscript *][superscript +]+D[superscript *][superscript -])/N(jet)=0.015±0.008(stat)±0.007(sys). This rate is consistent with perturbative QCD evaluation of gluon splitting into a pair of charm quarks and subsequent hadronization.
