KamLAND

Measuring the anti-neutrino flux from a large number of commercial nuclear reactors in Japan.

muon

MuCAP

High precision measurement of the singlet muon capture rate on the proton to dertermine the induced pseudoscalar form factor

MuLAN

High precision mesaurement of the positive muon lifetime to determine the Fermi coupling constant

CUORE and Cuoricino

Neutrinoless Double Beta Decay with cryogenic bolometers at Gran Sasso National Laboratory in Italy.

Parity Violation in Stable Atoms

Precision measurements of electroweak interaction parameters on a tabletop scale by measuring the parity-nonconserving transitions in ytterbium atoms. In collaboration with Prof. Budker.

Trapped Na21

Facility for Exotic Trapped Atoms: Sodium21

Measuring the beta-neutrino correlation using magneto-optically trapped radioactive atoms

Boron-8 Beta-Decay

Alpha and Neutrino Spectra from Boron-8 Beta-Decay

emiT

emiT tests a fundamental symmetry, time-reversal invariance, by measuring the correlations between the neutron spin and the momenta of the electron and proton. The experiment is located at the NIST cold neutron facility in Gaithersburg, MD.

Oxygen-14 Lifetime

Lifetime Measurement of Oxygen-14 as a Test of the Unitarity of the CKM Matrix

Experiments with Positronium

There are several experiments with positronium underway in our group. Among proposed are: invisible decays of positronium

NPDGamma

Measuring the weak nucleon-nucleon coupling, conducted at the Los Alamos Neutron Facility.

The Last Neutrino Mixing Angle (proposed)

Existing experiments have observed two of the mixing angles, but the final angle, theta-13, has not yet been determined. This experiment is a proposal to measure this final mixing angle with two moderately sized liquid scintillator detectors located near a nuclear reactor.
