Abstract

fetched live from OpenAlex

<!--HTML-->Hello! My name is Ash, I am a physics bachelors student from Canada entering my final year of studies. In this talk, I present an analysis of central diffractive events in proton–proton collisions using the CMS Precision Proton Spectrometer (PPS). By tagging protons and reconstructing vertex positions via timing detectors, we explore a class of photon-mediated interactions in a non-perturbative QCD regime. We study kinematic distributions in data and simulation, applying event selection, timing correlations, event mixing, and sideband subtraction to estimate and separate background. This is among the first physics analyses using PPS to study central diffraction at LHC energies, providing new insights into a poorly modeled 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.
