Searching for Tensor Currents in the Weak Interaction Using 8B β Decay

ORAL

Abstract

The β decays of the A = 8 system present a unique window to study several aspects of the electroweak interaction with unprecedented accuracy. Studying the β-α-ν correlation from the β decay of 8B tests the fundamental “vector minus axial vector” (V-A) nature of the weak interaction by searching for possible tensor couplings. Using the β-decay Paul Trap (BPT) at Argonne National Laboratory we report a limit on the tensor coupling in 8B. We will also discuss both improvements to the BPT system and to the production of 8B with the goal of collecting ~2·106 β-α-α coincidences.
