Searches for permanent electric dipole moments
Oral
I will review the impact of searches for electric dipole moments of nucleons, atoms and molecules on our knowledge of fundamental sources of CP (or T) violation in nature. The talk will focus on the use of effective field theory to disentangle the constraints on different fundamental CP-odd sources, and the recent interplay with direct LHC exclusion limits on possible models of new physics.

Searches for permanent electric dipole moments
Oral
A number of exciting technologies are under development that should allow for significant improvements in the sensitivity to neutron electric dipole moments. We will discuss the techniques and experiments that are underway and the status of the various efforts that plan to improve the sensitivity by a factors of 10 - 100.

Searches for permanent electric dipole moments
Oral
Results of the current measurements of neutron EDM in ILL will be presented. Prospects of increase in sensitivity of experiment due to UCN density increasing and the new scheme of UCN traps of EDM spectrometer will be discussed. The second part of the report will be devoted to preparation of UCN source with superfluid helium in PNPI.

Searches for permanent electric dipole moments
Oral
We are studying a new nEDM measurement in the region of < 10-27 e cm, which can be a clue to understand baryogenesis in the universe. For improving counting statistics, we are increasing UCN density by means of a superthermal method [1]. We have placed a He-II bottle at a temperature below 1 K in a spallation neutron source, where UCN production rate is optimized. The UCN transport is improved...

Searches for new forces
Oral
Neutron-antineutron oscillations provide an extremely sensitive probe
for new interactions that change baryon number by 2
units. The discovery of oscillations would have broad impact in
particle physics and cosmology: it would imply all matter
containing neutrons is ultimately unstable and could inform our understanding
of the matter-antimatter asymmetry in the universe. ...
