Study of collective modes of gluon in an anisotropic thermomagnetic medium
Bibliographic record
Abstract
Using the hard thermal loop (HTL) perturbation theory, we investigate the collective modes of gluon in an anisotropic thermal medium in the presence of a constant background magnetic field. The momentum space anisotropy of the medium has been incorporated into the distribution function via the generalized $`$Romatschke- Strickland' form. The magnetic modification arises from the quark loop contribution where the lowest Landau level approximation has been considered. We examine two special cases: i) spheroidal anisotropy with an anisotropy vector orthogonal to the external magnetic field, and ii) ellipsoidal anisotropy with two mutually orthogonal vectors describing aniostropies along and orthogonal to the field direction. We use the general structure of gluon self-energy that consists of six independent basis tensors. It is found that the strong background magnetic field has a significant impact on the growth rate of the unstable modes. This could have important effects on the equlibration of magnetized quark-gluon plasma.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
