  1. 2. FLARE: FCCee b2Luigi Automated Reconstruction And Event processing
    Cameron Harris
    10/29/25, 2:00 PM

    The FCCee b2Luigi Automated Reconstruction And Event processing (FLARE) package is an open source python based data workflow orchestration tool powered by b2luigi. FLARE automates the workflow of Monte Carlo (MC) generators inside the Key4HEP stack such as Whizard, MadGraph5_aMC@NLO, Pythia8 and Delphes. FLARE also automates the Future Circular Collider (FCC) Physics Analysis software...

  2. 25. PocketCoffea: Configuration Framework for CMS Analyses based on Coffea
    Felix Philipp Zinn (Rheinisch Westfaelische Tech. Hoch. (DE))
    10/29/25, 2:30 PM
    "Standard talk"

    PocketCoffea is an analysis framework based on Coffea for CMS NanoAOD events. It relies on a BaseProcessor class which processes the NanoAOD files in a columnar fashion.
    PocketCoffea defines a Configurator class to handle parameter, analysis workflow configurations such as datasets definition, object and event selection, event weights, systematic uncertainties and output histogram...

  3. 11. Workflows via ParaO - Parametrizing Objects
    Benjamin Fischer (RWTH Aachen University (DE))
    10/29/25, 3:00 PM
    "Standard talk"

    Luigi is a powerful workflow tool for data analyses. Yet, it has some limitations that become quite debilitating in larger and more complex workflows. The PyHEP.dev 2024 Talk waluigi - Beyond luigi outlined some basic principles and ideas that sought to address these shortcomings. Together with the feedback gathered from the...

  4. 10. Scattering Amplitude Reconstruction in Python
    Giuseppe De Laurentis (University of Edinburgh)
    10/29/25, 3:30 PM
    "Standard talk"

    Scattering amplitudes encode the chances of different outcomes when
    particles collide. Calculating them to the precision required by
    current and future colliders is extremely challenging: the
    intermediate steps explode in size and become unwieldy even for modern
    computers. Yet the final answers often turn out to be surprisingly
    simple and efficient to use, if only they can be...
