A permanent EDM of an elementary particle violates parity (P) and time reversal (T) symmetry, and assuming CPT invariance, T violation implies CP violation. EDM predicted by the Standard Model (SM) are far too small to be detected with current experimental techniques, therefore, any observation of non-zero EDMs would strongly indicate the existence of physics beyond the SM (BSM).
The muon is...
Electric dipole moment (EDM) of the muon is one of the least tested areas of the Standard Model (SM) of Particle Physics and any detected signal is a strong hint of physics beyond the SM. In this presentation, I will review the history of the searches for a muon EDM, current status of efforts at Fermilab and J-PARC, and the new effort at PSI.
In recent years, non-linear beam dynamics has been used to design novel manipulations that exploit multiple stable orbits in a single ring. In this presentation, an overview of the methods that have been developed will be carried out focusing on the possibility of devising new means for injecting or extracting beams from a circular accelerator.
The Standard Model (SM) of Particle Physics is not capable to account for the apparent
matter-antimatter asymmetry of our Universe. Physics beyond the SM is required and is either
probed by employing highest energies (e.g., at LHC), or by striving for ultimate precision and
sensitivity (e.g., in the search for electric dipole moments). Permanent electric dipole moments
(EDMs) of particles...

In 2019 we have measured the beam profiles of two potential muon beamlines at PSI. These measurements will permit the extraction of the transverse phase space for calculations of injection into a compact storage ring.
The muon g-2 experiment at Fermi National Accelerator Laboratory (FNAL E989) is using a super-ferric magnet to generate the nominally vertical precision magnetic field of 1.45 T which confines the muon beam in the horizontal plane (radial direction). A segmented electrostatic quadrupole system is employed to prevent the muon beam from spiraling out of the storage region in the vertical...
An overview of the forthcoming measurement of the muon EDM using the g-2 storage ring at Fermilab. The new tracking detectors, together with improved segmented calorimeters, allow for increased sensitivity to a precession plane tilt.
I will present the status and prospects of the muon EDM experiment by using a reaccelerated thermal muon beam at J-PARC
The Mu3e collaboration is building an ultra thin ~300 million pixel tracking detector in order to search for the the lepton-flavour violating decay of a positive muon to two positrons and and an electron at PSI. To this end, we have designed and tested a series of high-voltage active monolithic pixel sensors (HV-MAPS), the MuPix chips. The talk will present results from the latest fully...
A short summary of technologies for Depleted Monolithic Pixel Sensors (DMAPS) will provided in the talk.
The international JEDI (Jülich Electric Dipole moment Investigation) collaboration is preparing a first-ever direct measurement of the deuteron Electric Dipole Moment (EDM), using the COSY storage ring at Forschungszentrum Jülich (Germany).
A new polarimeter is required to detect the very slow and minuscule polarization change with time: starting
in 2016, we have designed, built and...
A status of polarized proton beams at RHIC, and on-going 3He developments. Review of polarized beam plans and studies for the EIC, including electron beam transfer, acceleration, and polarization lifetime at store. Add some insight into spin dynamics computational tools and methods.
The Muon g-2 experiment E989 at Fermilab will measure the anomalous magnetic moment of the muon, a$_\mu$, with about four times better precision than former experiments. The aim is to resolve the discrepancy of more than 3 standard deviations between the previous measurements dominated by the Brookhaven E821 result and the Standard Model calculation of a$_\mu$.
The experimental concept uses a...
Plastic scintillators (including scintillating fibers) coupled to photosensors provide flexible, fast and high granularity detectors which are able to work in high rate environment. The advent of Silicon PhotoMultipliers (SiPMs) has had a strong impact in the development of what we can call a ``new age" of plastic scintillator based detectors. Improved detector performances (better spatial...
