  1. 29. Geometry Calibration in IceCube

    Detectors, computing and software
    Contributed Talk

    The IceCube Neutrino Observatory at the South Pole has instrumented one cubic kilometer of ice by deploying digital optical modules (DOMs) in 86 drill holes, each containing a string of DOMs So far IceCube has used the GPS-determined location of the drill tower for the positions of DOMs in the transverse directions ($x$ and $y$) while the depth ($z$) is calibrated in situ. The large...

  2. 33. Radiation Hard 3D Silicon Pixel Sensors for use in the ATLAS Detector at the HL-LHC

    Contributed Talk

    The High Luminosity LHC (HL-LHC) upgrade requires the planned Inner Tracker (ITk) of the ATLAS detector to tolerate extremely high radiation doses. Specifically, the innermost parts of the pixel system will have to withstand radiation fluences above $1\times10^{16}$ $n_{eq}cm^{-2}$. Novel 3D silicon pixel sensors offer a superior radiation tolerance compared to conventional planar pixel...

    In high-energy physics it is a recurring challenge to efficiently and precisely (enough) calculate the global significance of, e.g., a potential new resonance. We propose a new method that models the significance in the search region as a Gaussian Process (GP). The kernel of the GP is approximated with a covariance matrix and is calculated with a carefully designed set of background-only data...

  4. 16. Overcoming limitations to parameter inference using Neural Ratio Estimation
    Gert Kluge, Dr Giacomo D'Amico (University of Bergen), Prof. Heidi Sandaker (University of Oslo, Department of Physics), Dr Julia Djuvsland (University of Bergen)

    Contributed Talk

    In the hunt for new physics phenomena, such as dark matter, it is
    crucial to compare experimental data to theoretical models. During this
    step, the most likely values of the model’s parameters — such as particle
    masses and cross sections — are inferred. However, a rigorous statistical
    treatment of such an inference is oftentimes not practically feasible with-
    out making significant...

  5. 19. Combined collider constraints on SUSY with a light gravitino
    Anders Kvellestad (University of Oslo)

    BSM physics
    Contributed Talk

    I will present the latest physics results from the GAMBIT Collaboration, focusing on a recent study of how the current combined set of LHC SUSY searches and LHC measurements of SM signatures constrain SUSY scenarios with multiple light neutralinos and charginos, and a near-massless gravitino. Through a large-scale global fit, with full Monte Carlo simulations of LHC searches and measurements...
