Open Charm Production in p + p and Pb + Pb collisions at the CERN Large Hadron Collider
Bibliographic record
Abstract
Effects of strong longitudinal colour electric fields (SCF), shadowing, and quenching on the open prompt charm mesons (D 0 , D +, D ∗ +, D s +) production in central Pb + Pb collisions at √ sNN = 2.76 TeV are investigated within the framework of the HIJING/BB v2.0 model. We compute the ¯ nuclear modification factor R D PbPb, and show that the above nuclear effects constitute important dynamical mechanisms in the description of experimental data. The strength of colour fields (as characterized by the string tension κ), partonic energy loss and jet quenching process lead to a suppression factor consistent with recent published data. Predictions for future beauty mesons measurements have been included. Ratios of strange to non-strange prompt charm mesons in central Pb + Pb and minimum bias (MB) p + p collisions at 2.76 TeV are also discussed. Minimum bias p + p collisions which constitute theoretical baseline in our calculations are studied at the centre of mass energies √ s = 2.76 TeV and 7 TeV.

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; a candidate call from one teacher head, not a consensus.
