222. Searches For Exotic Interactions with Slow Neutons

William Snow (Indiana University)

17/10/2016, 16:40

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

The ability of slow neutrons to interact coherently with macroscopic amounts of matter and with negligible decoherence opens an experimental window on certain aspects of beyond Standard Model physics. This talk will present results of some recent experiments which fit within this general category.

164. Time-Reversal Invariance Violation in Nuclei

Prof. Vladimir Gudkov (University of South Carolina)

Low energy precision tests of the Standard Model

Oral

Time Reversal Invariance Violating (TRIV) effects in neutron transmission through a nuclei target are discussed. We explore the possibility to search TRI violation using two important advantages of neutron nuclei interactions: the possibility of the enhancement of TRIV observables by many orders of magnitude, and the relatively large number of the nuclear targets, which provides the assurance...

241. SuperSUN – a new infrastructure for experiments with ultracold neutrons at ILL

Prof. Oliver Zimmer (Institut Laue Langevin)

17/10/2016, 17:30

Advanced muon and ultracold neutron sources

Oral

Conversion of cold to ultracold neutrons (UCNs) via single-phonon emission in superfluid helium has been proposed forty years ago by Golub and Pendlebury as a viable mechanism to achieve high densities of UCNs at the end of a neutron guide. Building on practical experience from two prototypes based on this mechanism, and able to provide UCNs to user experiments at room temperature, the new UCN...

173. A cold neutron beam facility for particle physics at the ESS

Torsten Soldner (Institut Laue Langevin)

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

Pulsed beams have tremendous advantages for precision experiments with cold neutrons. In order to minimize and measure systematic effects, they are used at continuous sources in spite of the related substantial decrease in intensity. At the pulsed neutron source ESS, such experiments will gain up to a factor of 30 in event rate, and novel concepts become feasible. Therefore, the cold neutron...

166. A novel neutron EDM search using a pulsed beam

Dr Florian Piegsa (ETH Zürich)

17/10/2016, 18:00

Searches for permanent electric dipole moments

Oral

The search for a finite CP-violating neutron electric dipole moment (nEDM) is motivated in order to understand the observed large matter-antimatter asymmetry in our universe. It has become a worldwide endeavour which is followed by various research teams setting up experiments for improved measurements. Recently, a novel concept to measure a nEDM has been brought forward [Phys. Rev. C 88,...

205. A New Search for Neutron-Anti-Neutron Oscillations

Gustaaf Brooijmans (Columbia University)

17/10/2016, 18:15

Searches for symmetry violations and new forces

Oral

Neutral particle oscillations have proven to be extremely valuable probes of fundamental physics. Kaon oscillations provided us with our first insight into CP-violation, fast B oscillations provided the first indication that the top quark is extremely heavy, B oscillations form the most fertile ground for the continued study of CP-violation, and neutrino oscillations suggest the existence of...
