  1. 50. Beam-induced background simulation studies for C^3
    Dimitris Ntounis (Stanford University & SLAC National Accelerator Laboratory)

    ORAL

    The Cool Copper Collider (C$^3$) is a proposed linear electron-positron linear collider operating at a center-of-mass energy of 250 GeV, with an upgrade to 550 GeV. A key aspect of evaluating the physics potential of any proposed Higgs factory is to quantify the effect of the various beam- and machine-induced backgrounds on the detector occupancy, and, ultimately, on the expected precision...

    While the ionization process by charged particles (dE/dx) is commonly used for particle identification, uncertainties in total energy deposition limit particle separation capabilities. To overcome this limitation, the cluster counting technique (dN/dx) leverages the Poisson nature of primary ionization, providing a statistically robust method for inferring mass information. Simulation studies...

    Detector studies for future experiments rely on advanced software tools to estimate performance and optimize their design and technology choices. The Key4hep project provides a turnkey solution for the full experiment life- cycle based on established community tools. An important ingredient for the performance of future Higgs Factory experiments, is the particle flow reconstruction for optimal...

    ORAL

    The challenges expected for the future $e^+e^-$ colliders era are pushing to re-think the HEP computing models at many levels.
    The evolution toward solutions that allow an effortless interactive analysis experience is one of the key topics foreseen by future colliders collaborations.

    In this context, EDM4HEP offers a high-level model which makes it a flexible and user-friendly tool for...

    ORAL

    The precise reconstruction of electrons is an important ingredient for the proposed physics program at future Higgs factories (HF). It becomes especially important in $m_W$ and TGC measurements in the $e\nu W$ final state. These measurements were identified as two of the high-priority focus topics by the WG1 of the ECFA HF study.
    The track reconstruction for electrons is particularly...

  9. 48. Machine Learning Flavour Tagging for Future Higgs Factories
    Mareike Meyer
    12/10/2023, 15:00
    ORAL

    Efficient heavy flavour tagging is essential for reaching the physics goals at future e+e- -collider-experiments, like for example the precise measurement of Higgs boson properties in the decay channels to bottom or charm quarks.
    In this talk the application of the CMS DeepJet tagger to the ILD detector concept for the ILC is presented. The performance of the tagger is compared to the current...

    ORAL

    Particle flow and flavor tagging are the key algorithms determining physics performance at reconstruction for Higgs factory detectors. Particle flow is the reconstruction of individual particles inside jets, which requires precise track-cluster matching in addition to clustering of calorimeter hits. We are implementing a track-cluster matching algorithm on top of GravNet-based calorimeter...

  12. 59. Machine Learning reconstruction for a Dual Readout calorimeter
    Adelina D'Onofrio (Istituto Nazionale di Fisica Nucleare), Biagio Di Micco (Istituto Nazionale di Fisica Nucleare), Michela Biglietti (Istituto Nazionale di Fisica Nucleare)
    ORAL

    The IDEA detector designed for the FCC-ee experiment has a cilindrical drift chamber as a main tracking device, surrounded by a spaghetti calorimeter exploiting a dual readout technology.
    The fibers are positioned 1.5 mm far from each other giving to the detector an high granularity of about 50 sensitive element per cm2.
    The Dual Readout technology, using scintillating and Cherenkov based...
