| Abstract: | The modern technologies of neutral atom traps and the production of ultra-cold neutrons (UCN) have opened up new vistas in the field of precision beta decay studies which search for physics outside the Standard Model. The TRINAT collaboration uses a magneto-optical trap and optical pumping techniques to produce a highly polarized source of short-lived 37K from which the positron and recoiling nucleus escape with negligible distortions to their momenta. The UCNA collaboration is utilizing the favourable aspects of UCN (may be transported far from production backgrounds and are easily polarized) to measure correlations. These two experiments are discussed in the context of measuring the Vud element of the CKM mass-mixing matrix and as a test of weak right-handed currents. |
