In the 40 years since the landmark E122 experiment, parity violating electron scattering (PVES) has proven to be a versatile and precise tool in both setting limits on beyond the standard model physics and in determining properties of nuclear matter. Its appeal stems from the use of the cleanly interpretable weak neutral current. Updated experimental techniques will allow a new generation of...

Searching for new particles beyond the standard model is crucial for understanding several fundamental conundrums in physics and astrophysics. Several hypothetical particles can mediate exotic spin-dependent interactions between ordinary fermions, which enable laboratory searches via the detection of the interactions. We present a novel platform for investigating exotic spin-dependent...

The P2 collaboration prepares a precise determination of the weak mixing angle at low energy at the upcoming MESA accelerator in Mainz. The projected relativce accuracy is 0.15% which is comparable to the existing measurements at the Z-pole. This accuracy will allow for a test of the Standard Model up to a mass scale of 50 TeV.
The experimental method, the measurement of the parity...

Searches for finite permanent electric dipole moments (EDM) of fundamental systems with spin are among the most sensitive experimental tests of parity and time reversal symmetry. Invoking the CPT theorem, they also test the CP symmetry between matter and antimatter. Values of EDM from various fundamental particles and systems offer complementary information concerning the potential sources of...

The ability to manipulate or measure a particle's spin played a
key role in the rise of the Standard Model (SM), and it continues to be
crucial to the elucidation of physics that the SM cannot explain.
Hints, e.g., to the origin of dark matter, of the cosmic surfeit of baryons,
or of the weak scale could conceivably come from experiments that exploit
spin degrees of freedom. I...

A permanent electric dipole moment (EDM) of the neutron would violate parity and time reversal symmetry. Assuming CPT to be a good symmetry of nature, this implies a CP symmetry violation as well. Thus, observing or further limiting the existence of the neutron EDM beyond the current best measurement sensitivity of 3x10^-26 ecm would increase our understanding of the Baryon Asymmetry of the...

Based on fundamental symmetries, we would naively expect the permanent electric dipole moment (EDM) of atoms to be identically zero. This is because EDMs are symmetric under time reversal, while the spin of the atom is not, and so any particle having spin and an EDM correlated to that spin would violate time reversal symmetry, as well as parity. Due to the CPT theorem, EDMs also violate...

Precision measurement of the Zeeman splitting in a two-state system is important for magnetometry, as well as the search for physics beyond the Standard Model. The most precise tests of new physics are often realized
in differential experiments that compare the transition frequencies of two co-located clocks, typically radiating on their Zeeman or hyperfine transitions. The advantage of...

In this talk we report on the results of the experimental search for a permanent electric dipole moment of 129Xe (Xe-EDM) performed by the MIXed-collaboration. Our approach is to detect the free spin precession of hyperpolarized 129Xe nuclear spins and search for frequency changes correlated with the direction of an applied electric field. To eliminate frequency changes caused by magnetic...

Measurements of electric dipole moments (EDMs) in atoms, molecules and neutrons serve as sensitive probes of new physics. We give a brief overview of atomic EDM theory [1] and discuss several recent applications of EDM-based measurements to search for new particles.
New bosons can mediate anomalous forces between standard-model particles. Using data from existing atomic and molecular EDM...

Understanding high precision spin dynamics in storage rings is one of major concerns for the JEDI collaboration’s EDM experimentation at COSY. We report here recent results on the impact of synchrotron oscillations on spin rotations at large spin coherence time needed for enhancing feeble EDM signal. A particular emphasis will be on salient features of the Spin Echo phenomenon in storage rings...

The JEDI Collaboration (Jülich Electric Dipole Investigations, http://collaborations.fz-juelich.de/ikp/jedi) aims for a measurement of the electric dipole moments (EDMs) of deuterons and protons at the COoler SYnchrotron (COSY). To make this possible, a novel high precision waveguide RF Wien filter was installed in COSY inside a so-called low-beta section, to modulate the spin of deuterons and...

Since several decades people search for the electric dipole moment (EDM) of the neutron, an unambiguous manifestation of parity (P) and time reversal symmetry (T) violation. Assuming the conservation of CPT, T violation in a fundamental system also means CP violation. This has only been observed in very few systems in the Standard Model of particle physics (SM) as a tiny effect. However, it...

We propose a program of measurements of electric and magnetic dipole moments of charm, beauty and strange baryons at the LHC, based on the phenomenon of spin precession as induced by the intense electromagnetic field between atomic planes of bent crystals. Studies of crystal channeling and spin precession of positively- and negatively-charged particles are presented, along with the expected...

The electric dipole moment (EDM) is a very sensitive probe of CP violation beyond the standard model, and it is measured in many systems such as atoms, neutrons, etc.
The EDM of composite systems may be sensitive to several CP violating processes at the elementary level, but the theoretical evaluations of the CP violation at different physical (atomic, nuclear, hadronic) hierarchies are...

all CP violating operators up to dimension 6 that contribute to the neutron EDM.
These include the Theta-term, quark EDM, quark chromo EDM, Weinberg and 4-quark
