Searches for symmetry violations and new forces
Oral
Axions, axion-like particles (ALPs), dilatons, and other ultralight (masses from 10-4 down to 10-23 eV) particles have been discussed as possible candidates for dark matter. An interesting feature of these ideas is that they lead to predictions of potentially observable transient and oscillating effects. I will describe how we are looking for these as well as the relation of such experiments...

Low energy precision tests of the Standard Model
Oral
In this talk I review the status of flavour physics. I first discuss the theoretical progress of the Standard Model calculations and how they compare to the experimental measurements of BELLE, BABAR, LHCb and MEG. While most observables are in excellent agreement with the theory predictions, in the last years hints for lepton flavor non-universality in channels with muons and tau leptons...

Searches for symmetry violations and new forces
Oral
We report updates of experimental constraints on new gravity-like interactions by measuring the angular distribution of cold neutrons scattering off atomic xenon gas. The results improved previous upper limit on Yukawa-type parametrization space in the 4 to 0.04 nm range by a factor of up to 10[1]. We also discuss about our plans of a test of the weak equivalence principle and a new force...

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles
Oral
High precision measurements of the beta spectrum from neutron and nuclear decay are a sensitive probe for beyond standard model physics. In particular, exotic scalar and tensor couplings can produce Fierz terms which introduce a characteristic distortion to the standard model spectrum, inversely proportional to the beta energy. Employing silicon detectors, with understood charge collection...

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles
Oral
The aCORN Collaboration has analyzed data taken on the NG-6 beamline at the NIST (National Institute of Standards and Technology) Center for Neutron Research and achieved the most precise measurement to date of the angular correlation (a-coefficient) between the electron and antineutrino emitted in free neutron beta decay. Such a measurement provides a test of the Electroweak Standard Model...
