These baryons are known to exhibit beta decay into an electron, neutrino, and another particle when not bound in a nucleus.
The CryoEDM experiment places these entities in liquid Helium in order measure one of their properties which is currently bounded at 2.9 x 10−26 e-cm. If their aforementioned dipole moment is found to be nonzero, it would imply violation of CPT symmetry. The type of particles used in this experiment are, as other types, described by temperature related terms such as Ultracold and (*) Thermal. Rapid capture of these particles occurs in the R process in supernovae which produce most of the elements heavier than Iron. These baryons are known to exhibit beta decay into an electron, neutrino, and another particle when not bound in a nucleus. FTP, name this nucleon composed of 2 down quarks and an up quark, the uncharged counterpart of the proton.
