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. [...]

A Revised Experimental Upper Limit on the Electric Dipole Moment of the Neutron

Tech. Bund.) ; Geltenbort, P (Laue-Langevin Inst.) ; Green, K (Guelph U. ; Rutherford) et al.
We present for the first time a detailed and comprehensive analysis of the experimental results that set the current world sensitivity limit on the magnitude of the electric dipole moment (EDM) of the neutron. We have extended and enhanced our earlier analysis to include recent developments in the understanding of the effects of gravity in depolarizing ultracold neutrons (UCN); an improved calculation of the spectrum of the neutrons; and conservative estimates of other possible systematic errors, which are also shown to be consistent with more recent measurements undertaken with the apparatus.

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. [...]

(PSI, Villigen) ; Craievich, P. (PSI, Villigen) ; Dehler, M. (PSI, Villigen) ; Frei, F. (PSI, Villigen) et al.
The SwissFEL Injector Test Facility operated at the Paul Scherrer Institute between 2010 and 2014, serving as a pilot plant and test bed for the development and realization of SwissFEL, the x-ray Free Electron Laser facility under construction at the same institute. The test facility consisted of a laser-driven rf electron gun followed by an S-band booster linac, a magnetic bunch compression chicane and a diagnostic section including atransverse deflecting rf cavity.

Psychological bias towards, or away from, a prior measurement or a theory prediction is an intrinsic threat to any data analysis. While various methods can be used to avoid the bias, e.g. [...]

In April 2021, scientists active in muon physics met to discuss and work out the physics case for the new High-Intensity Muon Beams (HIMB) project at PSI that could deliver of order $10^{10}$ s$^{-1}$ surface muons to experiments. [...]

Modified lepton couplings and the Cabibbo-angle anomaly
/ Manzari, Claudio Andrea (Zurich U. ; PSI, Villigen) ; Coutinho, Antonio M. (PSI, Villigen) ; Crivellin, Andreas (Zurich U. ; PSI, Villigen ; CERN)
Significant discrepancies between the different determinations of the Cabibbo angle have been observed. Here, we point out that this "Cabibbo-angle anomaly" can be explained by lepton flavour universality (LFU) violating New Physics (NP) in the neutrino sector. [...]

Searching for Lepton Flavour (Universality) Violation and Collider Signals from a Singly-Charged Scalar Singlet
/ Crivellin, Andreas (CERN ; Zurich U. ; PSI, Villigen) ; Kirk, Fiona (Zurich U. ; PSI, Villigen) ; Manzari, Claudio Andrea (Zurich U. ; PSI, Villigen) ; Panizzi, Luca (Uppsala U.)
In recent years, evidence for lepton flavour universality violation beyond the Standard Model has been accumulated. In this context, a singly charged $SU(2)_L$ singlet scalar ($\phi^\pm$) is very interesting, as it can only have flavour off-diagonal couplings to neutrinos and charged leptons, therefore necessarily violating lepton flavour (universality).
