Web4 de jul. de 2024 · The “Higgs mechanism,” which consists of the Higgs field and its corresponding Higgs boson, is said to give mass to elementary particles. By “mass” we mean the inertial mass, which resists when we try to accelerate an object, rather than the gravitational mass, which is sensitive to gravity. WebWelcome to the tutorial for the HiggsDNA (Higgs to Diphoton NanoAOD) framework! The HiggsDNA repository provides tools for running a Higgs to diphoton analysis. 1. Introduction HiggsDNA provides tools for developing and executing Higgs to diphoton analyses, starting from the nanoAOD data tier.
