Charmed baryons are actively studied in Belle experiment
and measurements on spin-related phenomena such as
weak decay asymmetries are obtained recently.
In this talk, we will report the determination of
$\Xi_c(2970)$ spin-parity and the measurements of
decay asymmetries in $\Xi_c$ weak decays.
In addition, other results on charmed baryon will be
presented if time allows.
One of the key open questions on the nature of the neutrino is whether it is a Dirac or a Majorana particle. If the neutrino is a Majorana particle, then the interference terms that break the time-reversal symmetry of muon decay appear as the transverse spin polarization of the decay electron [1]. Experiments have been performed at Paul Scherrer Institute to measure the spin polarization of...
The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims to measure the neutron electric dipole moment (EDM) with a sensitivity of $10^{-27} e·\rm cm$ with a high-intensity ultracold neutron (UCN) source. Our target accuracy is an order-of-magnitude improvement over the current best experimental limit of the neutron EDM [1]. In the neutron EDM measurement, the Larmor precession...
Polarization facilities are being developed at the JINR accelerator complex in the framework of the polarization research program under the NICA project. Those are the polarized deuteron and proton source SPI, SPI low energy and linac output polarimeters, and the absolute polarimeter at the NICA collider. The status of the above facilities and the results achieved are presented.
