Higgs Physics with the XFEL Compton $\boldsymbol{\gamma\gamma}$ Collider Concept at $\boldsymbol{\sqrt{s}=125}$ GeV

Ariel Schwartzman, Tim Barklow, Umar Sohail Qureshi

An XFEL-based γγ collider at 125 GeV can measure Higgs properties with high precision by applying set transformer machine learning to particle data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our results demonstrate that an XFEL γγ collider can probe the Higgs sector with extremely high precision and enable new physics opportunities, complementary to proposed e+e- machines.

C2weakest assumption

The set transformer-based deep learning framework that acts on particle-flow object point clouds, when coupled with a genetic algorithm optimizer, yields significantly higher sensitivity than traditional methods for signal-background discrimination in the Higgs final states.

C3one line summary

An XFEL Compton gamma-gamma collider at 125 GeV with a set transformer deep learning classifier on particle-flow point clouds can achieve high-precision Higgs measurements across hadronic, semi-leptonic, and leptonic final states including H to strange quarks.
