Ultracold molecules have important applications that range from quantum simulation and computation to precision measurements probing physics beyond the Standard Model. Optical tweezer arrays of laser-cooled molecules, which allow control of individual particles, offer a platform for realizing this full potential. In this work, we report on creating an optical tweezer array of laser-cooled calcium monofluoride molecules. This platform has also allowed us to observe ground-state collisions of laser-cooled molecules both in the presence and absence of near-resonant light.

First Time

The FINUDA experiment has performed a systematic study of the Mesonic Weak Decay (MWD) of Λ hypernuclei by analyzing all the data collected from 2003 up to 2007. Negatively charged pion spectra from mesonic decay were measured with magnetic analysis for the first time for [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]. Branching ratio Γπ-/Γtot were derived from the measured spectra. Based on these measurements, the spin-parity assignment 1/2+ for [Formula: see text] and 5/2+ for [Formula: see text] ground-state are confirmed and a spin-parity 3/2+ for [Formula: see text] ground-state is assigned for the first time. Ideas for precision measurements of MWD at the J-PARC accelerator's complex are finally presented.
