Probing New Physics in Dimension-8 Neutral Gauge Couplings at $e^+e^-$ Colliders / Ellis, John ; He, Hong-Jian ; Xiao, Rui-Qing
Neutral triple gauge couplings (nTGCs) are absent in the standard model effective theory up to dimension-6 operators, but could arise from dimension-8 effective operators. [...]

High spatial resolution monolithic pixel detector in SOI technology / Bugiel, Roma (AGH University of Science and Technology (PL)) ; Bugiel, Szymon (AGH University of Science and Technology (PL)) ; Dannheim, Dominik (CERN) ; Fiergolski, Adrian (CERN) ; Hynds, Daniel (Nikhef National institute for subatomic physics (NL)) ; Idzik, Marek (AGH University of Science and Technology (PL)) ; Kapusta, Piotr (Polish Academy of Sciences (PL)) ; Munker, Magdalena (CERN) ; Nurnberg, Andreas Matthias (KIT - Karlsruhe Institute of Technology (DE)) ; Spannagel, Simon (Deutsches Elektronen-Synchrotron (DE)) et al.
This paper presents test-beam results of monolithic pixel detector prototypes fabricated in 200 nm Silicon-On-Insulator (SOI) CMOS technology studied in the context of high spatial resolution performance. The tested detectors were fabricated on a 500 μm thick high-resistivity Floating Zone type n (FZ-n) wafer and on a 300 μm Double SOI Czochralski type p (DSOI Cz-p) wafer. [...]
