Collision of particles and energy extraction in hyperscaling violation background
Bibliographic record
Abstract
In this paper, we investigate particle collision near the charged black hole with hyperscaling violating factor under different conditions on mass, charge and θ parameters. In that case, we calculate the center of mass (CM) energy of two colliding particles on the black hole horizon. We find that unlike the other stationary black holes that have been studied so far, the center of mass energy on the horizon can be infinite in certain conditions. By computing the effective potential, we found that particles can collide with very high CM energy on the horizon at two states. The first is an uncharged black hole with small mass and small θ. The second is a massive black hole with the small value of charge and θ. In addition, we investigate the geodesic motion of particles and plot some possible orbits around this black hole. Then, we obtain the ergosphere extent of the hyperscaling violation charged black hole and found that increasing value of θ, the ergoregion limit reduces and we can not extract energy with large value of θ. We also found that energy extraction from the black hole only depends on the absorbed charge by the black hole.

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.
