Parallel contribution
At the new ultracold neutron source at the Paul Scherrer Institut(PSI) a collaboration of 15 European institutions is setting up an experiment to search for the nEDM with improved sensitivity. The same apparatus which provided the present best limit on the nEDM (d < 2.9 x 10-26 ecm 90% CL, Baker et al., Phys. Rev. Lett. 97 (2006) 131801), was moved from the Institut Laue Langevin (ILL) in...

The experimental search for a neutron electric dipole moment could reveal new sources of time-reversal (T) and charge-conservation-and-parity (CP) violation and challenge proposed extensions to the Standard Model. The goal of the present experiment is to improve the measurement sensitivity of the neutron EDM by two orders of magnitude.
The physics goals of this experiment remain timely and...

The Electric Dipole Moments (EDMs) provide an unique way of probing CP violations. The search for neutron and atom EDMs has reached very high precision after many decades of effort. I will discuss the implications of the EDM search on the theory of SM, SUSY, as well as the Baryogenesis scenarios. In particular, based on the study of the interplay of EDMs and electroweak Baryogenesis in MSSM,...

Parallel contribution
High intensity polarized proton beams in storage rings make possible the development of an experiment to probe the proton electric dipole moment (EDM) with sensitivity of 10^-29 e-cm. At this level it will be sensitive to new physics at the 3000 TeV and if new physics exists at the LHC scale, it will be sensitive at the sub-micro-radian level of CP-violating phases. The method utilizes an...

The goal of the Mu2e experiment is to improve on the existing experimental limits for the neutrinoless conversion of a muon into an electron by four orders of magnitude. Such sensitivity means that if low-energy supersymmetry is discovered at the LHC, Mu2e will provide complimentary information. Even in the absence of new physics at the TeV scale, Mu2e could still find evidence for new...

Fermilab E989 has the goal to improve on the precision of the muon anomalous magnetic moment, a_mu = (g_mu - 2)/2 by at least a factor of 4 beyond the 0.54~ppm relative precision obtained in E821 at Brookhaven. The precision storage ring will be relocated to Fermilab and installed in a new building. A new 8~GeV/c proton beamline and 3.1~GeV/c muon beamline will be built. The unique...

The Enriched Xenon Observatory (EXO) is an experimental program designed to search for the neutrinoless double beta decay (0nbb) of Xe-136. Observation of 0nbb would determine an absolute mass scale for neutrinos, prove that neutrinos are massive Majorana particles (indistinguishable from their own antiparticles), and constitute physics beyond the Standard Model. The current phase of the...

We present the results of direct searches for light new physics with BABAR. In particular, we describe studies of narrow Upsilon and B decays with sensitivity to possible light pseudoscalar Higgs bosons and invisibly decaying dark matter candidates. We also present results of searches for hidden sector gauge and Higgs bosons.

We have obtained a very accurate proton charge distribution radius by measuring the 2s-2p Lamb shift in muonic hydrogen[1]. The value we found, 0.84184(67)fm is roughly 10 times more accurate than the ones derived from either hydrogen spectroscopy or electron-proton elastic scattering. It is 5 standard deviations away from the CODATA 2008 value 0.8768(69) fm, which combines both types of...

The Fermi constant, G_F, describes the strength of the weak force and
is determined most precisely from the mean life of the positive muon,
tau_mu. Advances in theory have reduced the theoretical uncertainty on
G_F as calculated from tau_mu to a few tenths of a part per million
(ppm). Until recently, the remaining uncertainty on G_F was...

The Qweak experiment at Jefferson Lab measures the parity violating
asymmetry of polarized electrons scattering of a proton target at very
low momentum transfer. In the Standard Model, this asymmetry reveals
the proton’s coupling to the neutral vector current, the weak charge.
This value, measured directly for the first time, provides a precision
test of the Standard Model and constrains...
