w-boson-mass — task data

Evaluation data for the Terminal-Bench-Science task physical-sciences/physics/w-boson-mass (W boson mass from W → μν and Z → μμ candidates). Licensed for evaluation of the Terminal-Bench-Science benchmark only; any other use, including training machine-learning models, is not permitted (see LICENSE). The canary string above marks it for exclusion from training corpora.

Layout (the Terminal-Bench-Science convention):

• w-boson-mass/input/mc/ — the simulation the agent analyses with, in the clear (pulled into the agent and verifier images): mc_w, mc_z, mc_dy_wsel and mc_tnp (Z tag-and-probe) as parquet files, the decay angular coefficients and their README.md.
• w-boson-mass/input/dev/ — the two development datasets the agent sees, in the clear (pulled into the agent image only): w.parquet, z.parquet and tnp.parquet each, and the true W mass of dev_01.
• w-boson-mass/verification/enc/ — the withheld evaluation datasets (the same three files each) and the verifier's truth file, encrypted (AES-256-CTR; each file named by a random identifier). They are pulled into the verifier image only and decrypted there at build time with the key, which ships only in the task's tests/ directory (never in this repository) and which the verifier build deletes once every file is decrypted and checked. No plaintext of the withheld datasets or of their answers is stored here.

Files are fetched at image build time, pinned to a commit of this repository and checked against per-file sha256 sums in the task (the ciphertext before decryption, the plaintext after). This copy serves the review of the task; it is removed once the data are mirrored into harborframework/terminal-bench-science-lfs. Earlier commits hold superseded versions of the task data; the task pins the commit it uses.

The QCD records enter only the multijet events of the datasets; no multijet simulation is shipped. CMS Open Data is released under CC0 1.0 and remains freely available from the CERN Open Data portal; the evaluation-only licence covers only the author's derived files in this repository.

Neither the experiment(s) (CMS) nor CERN endorse any works, scientific or otherwise, produced using these data.

This is not a CMS result; the injected W masses and detector and modelling variations of the evaluation datasets are synthetic and carry no physics meaning outside the benchmark.
