Hyperon signatures in the PANDA experiment at FAIR
/ PANDA Collaboration
We present a detailed simulation study of the signatures from the sequential decays of the triple-strange pbar p -> Ω+Ω- -> K+ΛbarK- Λ -> K+pbarπ+K-pπ- process in the PANDA central tracking system with focus on hit patterns and precise time measurement. [...]

We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with ultracold neutrons (UCN). Our measurement stands in the long history of EDM experiments probing physics violating time reversal invariance. [...]

Optically pumped Cs magnetometers enabling a high-sensitivity search for the neutron electric dipole moment
/ Abel, C. (Sussex U.) ; Afach, S. (PSI, Villigen ; Zurich, ETH) ; Ayres, N.J. (Sussex U. ; Zurich, ETH) ; Ban, G. (Caen U.) ; Bison, G. (PSI, Villigen) ; Bodek, K. (Jagiellonian U.) ; Bondar, V. (PSI, Villigen ; Zurich, ETH ; Leuven U.) ; Chanel, E. (U. Bern, AEC) ; Chiu, P.-J (PSI, Villigen ; Zurich, ETH) ; Crawford, C.B. (Kentucky U.) et al.
An array of sixteen laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 2016. It was deployed to measure the gradients of the experiment's magnetic field and to monitor their temporal evolution. [...]

Search for Darkonium in $e^+e^-$ Collisions
/ BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

Effects of Bias and Temperature on the Dose-Rate Sensitivity of 65-nm CMOS Transistors
/ Borghello, Giulio (CERN) ; Faccio, Federico (CERN) ; Termo, Gennaro (CERN) ; Michelis, Stefano (CERN) ; Costanzo, Sebastiano (CERN) ; Koch, Henri D (CERN) ; Fleetwood, Daniel M (Vanderbilt U.)
MOS transistors in 65-nm CMOS technology exposed to ultrahigh total ionizing dose (TID) levels show clear evidence of a true dose-rate (DR) dependence. In order to assess the impact of this effect and to understand its origin, an extensive measurement campaign has been carried out at different DRs, different temperatures, and different biases. [...]

Extending a 65nm CMOS process design kit for high total ionizing dose effects

Standard CMOS Process Design Kits (PDKs) do not address degradation the technology incurs when exposed to high Total Ionizing Dose (TID). Front-end electronics for the High-Luminosity Large Hadron Collider are expected to be exposed up to ten-fold doses. [...]

Ten-fold radiation levels are expected in the upgrade of the High-Luminosity Large Hadron Collider (HL-LHC) at CERN. Bulk silicon CMOS at 65 nm offers appreciable advantages among cost, performance, and resilience to high Total Ionizing Dose (TID). [...]

Production and decay of $\eta^\prime$(958) and $\eta$(1440) in $\bar{p} p$ annihilation at rest
/ Amsler, Claude (U. Zurich (main)) ; Anisovich, A V (U. Bonn (main)) ; Baker, C A (Rutherford) ; Barnett, B M (U. Bonn (main)) ; Batty, C J (Rutherford) ; Blum, P (Karlsruhe U.) ; Braune, K (LMU Munich (main)) ; Credé, V (U. Bonn (main)) ; Crowe, K M (LBNL, Berkeley) ; Doser, M (CERN) et al.
We report on a study of four reactions in $\bar{\mathrm p}{\mathrm p}$ annihilation at rest, of $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^-\eta$, $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^- 2\pi^0$, $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^-\gamma$ and $\bar{\mathrm p}{\mathrm p}\rightarrow 4\pi^0\eta$. The $\eta^\prime$ and the $\eta$(1440) are seen in their decays into $\pi^ + \pi^-\eta$, $\pi^0\pi^0\eta$ and $\pi^ + \pi^-\gamma$ ; no signal is seen in the $4\pi$ invariant mass distribution. [...]
