Dept. ; LBL, Berkeley) ; Frangipane, Evan (UC, Berkeley ; LBL, Berkeley) ; Garcia-Sciveres, Maurice (LBL, Berkeley) ; Jeanty, Laura (LBL, Berkeley) ; Nachman, Benjamin (LBL, Berkeley) ; Pagan Griso, Simone (LBL, Berkeley) ; Wang, Fuyue (LBL, Berkeley ; Tsinghua U., Beijing)
The pixel detectors for the High Luminosity upgrades of the ATLAS and CMS detectors will preserve digitized charge information in spite of extremely high hit rates. Both circuit physical size and output bandwidth will limit the number of bits to which charge can be digitized and stored. [...]

Finding symmetry breaking order parameters with Euclidean neural networks
/ Smidt, Tess E. (LBL, Berkeley ; Tsinghua U., Beijing) ; Geiger, Mario (LBL, Berkeley ; CERN ; Ecole Polytechnique, Lausanne) ; Miller, Benjamin Kurt (LBL, Berkeley ; Tsinghua U., Beijing ; Freie U., Berlin)
Curie's principle states that "when effects show certain asymmetry, this asymmetry must be found in the causes that gave rise to them". We demonstrate that symmetry equivariant neural networks uphold Curie's principle and can be used to articulate many symmetry-relevant scientific questions into simple optimization problems. [...]

Directional Detection of Light Dark Matter with Polar Materials
/ Griffin, Sinead (UC, Berkeley ; LBL, Berkeley) ; Knapen, Simon (UC, Berkeley ; LBL, Berkeley) ; Lin, Tongyan (UC, Berkeley ; LBL, Berkeley ; UC, San Diego) ; Zurek, Kathryn M. (UC, Berkeley ; LBL, Berkeley ; CERN)
We consider the direct detection of dark matter (DM) with polar materials, where single production of optical or acoustic phonons gives excellent reach to scattering of sub-MeV DM for both scalar and vector mediators. Using Density Functional Theory (DFT), we calculate the material-specific matrix elements, focusing on GaAs and sapphire, and show that DM scattering in an anisotropic crystal such as sapphire features a strong directional dependence.

A new paradigm for data-driven, model-agnostic new physics searches at colliders is emerging, and aims to leverage recent breakthroughs in anomaly detection and machine learning. In order to develop and benchmark new anomaly detection methods within this framework, it is essential to have standard datasets. [...]

Search for Majorana neutrinos exploiting millikelvin cryogenics with CUORE
/ CUORE Collaboration
The possibility that neutrinos may be their own antiparticles, unique among the known fundamental particles, arises from the symmetric theory of fermions proposed by Ettore Majorana in 1937. Given the profound consequences of such Majorana neutrinos, among which is a potential explanation for the matter-antimatter asymmetry of the universe via leptogenesis, the Majorana nature of neutrinos commands intense experimental scrutiny globally; one of the primary experimental probes is neutrinoless double beta ($0 \nu \beta \beta$) decay.
