Abstract

fetched live from OpenAlex

Data Description These datasets are generated as a series of test sets for anomalous jet tagging at the LHC. They include boosted W jets, Top jets and Higgs jets. Jet transverse momentum is focused around 600 GeV. Each file includes 100k original events from MadGraph, but might have slightly less events in the final h5 files due to fatjet pre-selection. Production processes include: pp -> W' -> W (jj) Z(\(\nu \nu\)); \(m_{W} = 59, 80, 120, 174 ~GeV\) pp -> Z' -> t t~; \(m_t=80, 174 ~GeV\) pp -> HH -> (hh) (hh), (h -> bb); \(m_H=174~GeV\), \(m_h = 20, 80 ~GeV\) Data Generation Jet samples in this dataset are generated with MadGraph, Pythia8 and Delphes (no pile-up effects simulated). Particle flow objects are used to cluster jets. FastJet was used for jet clustering. Jets are clustered using anti-kt algorithm with cone size R=1.0. Leading jet: \(p_T>450 \textrm{GeV}\); sub-leading jet: \(p_T>200 \textrm{GeV}\) Data Structure To get jets: f['objects/jets'] For jets, there are two datasets: ['constituents', 'obs']. (jets information is stored with higher-pt jet first) `obs[:, n_j - 1]`: jet four vectors and n-subjettiness for (n_j -1) th jet (pt, eta, phi, m, tau1, tau2, tau3, tau4, tau5) pt-sorted (highest first) jet constituents information are stored in variable length arrays for (n_j -1) th jet `constituents[:, n_j - 1]`: \(\{ E_i, P_{xi}, P_{yi}, P_{zi}, \textrm{PID}_i\}\) (PID: PDG for tracks; [22] for photon; [0] for neutral hadron) Extra Notes Since the dataset is structured as events, for W jet samples, only leading jet is available; while for Top and Higgs jets, leading and sub-leading jets are both valid. One might need to restrict jet \(p_T\) range at use. e.g. to get leading jet constituents: `f["objects/jets/constituents"][:,0]` The file names are self-explanatory on the corresponding generation process.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
