Beschreibung:
<jats:p>We discuss the impact of heavy-flavor production measurements in semi-inclusive deep inelastic scattering at HERA on the CTEQ-TEA PDFs.
In particular, we study the impact of the latest charm and bottom production measurements from the H1 and ZEUS collaborations on the gluon,
and the interplay of these measurements with the data ensemble of the recent CT18 global QCD analysis. </jats:p>
