Abstract
We provide comprehensive investigations for the mass spectrum of exotic open-flavor charmed/bottom $sq\overline{q}\overline{c}$, $qq\overline{q}\overline{c}$, $sq\overline{q}\overline{b}$, $qq\overline{q}\overline{b}$ tetraquark states with various spin-parity assignments ${J}^{P}={0}^{+},{1}^{+},{2}^{+}$ and ${0}^{\ensuremath{-}}$, ${1}^{\ensuremath{-}}$ in the framework of QCD sum rules. In the diquark configuration, we construct the diquark-antidiquark interpolating tetraquark currents using the color-antisymmetric scalar and axial-vector diquark fields. The stable mass sum rules are established in reasonable parameter working ranges, which are used to give reliable mass predictions for these tetraquark states. We obtain the mass spectra for the open-flavor charmed/bottom $sq\overline{q}\overline{c}$, $qq\overline{q}\overline{c}$, $sq\overline{q}\overline{b}$, $qq\overline{q}\overline{b}$ tetraquark states with various spin-parity quantum numbers. In addition, we suggest searching for exotic doubly-charged tetraquarks, such as $[sd][\overline{u}\overline{c}]\ensuremath{\rightarrow}{D}_{s}^{(*)\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{-}}$ in future experiments at facilities such as BESIII, BelleII, PANDA, LHCb, and CMS, etc.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
