A Material Frame: Hard Recoils from Slow Force Carriers
Francesco Serra
The paper proposes a modification of the Standard Model where the photon’s longitudinal component becomes a physical, ultra‑slow mode, breaking gauge and Lorentz invariance, and st…
Intrinsic Spatial Position Resolution of P-type Point-Contact Germanium Detector
R. M. J. Li, S. K. Liu, S. T. Lin +8
The paper presents a method to quantify the intrinsic spatial position resolution of p-type point‑contact germanium detectors using optimized cross‑scanning and pulse‑shape analysi…
Node-locked phase of annual modulations from the gravitational chiral anomaly in the solar Kerr field
M. Misiaszek
The paper examines how a parity‑odd curvature invariant of the Sun’s Kerr field could generate a predictable annual phase shift in dark‑matter‑like signals, and compares two simple…
High Negative Ion Gain MMThGEM-Micromegas Detector for Directional Dark Matter Searches
A. G. McLean, S. Higashino, R. R. Marcelo Gregorio +2
The paper reports the first high‑gain operation of a combined MMThGEM‑Micromegas detector in low‑pressure SF₆, achieving record negative‑ion gas gains and demonstrating directional…
The Darkside-20k Data Acquisition System
Fabio Acerbi, Pushparaj Adhikari, Paolo Agnes +289
The paper describes the data acquisition (DAQ) system for the DarkSide‑20k liquid‑argon dark‑matter detector, which uses continuous, trigger‑less digitisation of 2720 SiPM channels…
The Role of Symmetries in Dark Matter Detector Design
Benjamin Lillard, Jack D. Shergold, Juri Smirnov
The paper shows how the symmetries of anisotropic materials can be used to estimate the daily modulation signal in sub‑GeV dark‑matter detectors, enabling fast screening of molecul…
