Hace 3 horas · The above equation shows that a hypertriton produced from the coalescence of polarized proton, neutron, and Λ hyperon can acquire a non-zero polarization. To see this quantitatively, we extend the blast-wave model of Ref. [42] to include the polarization of particles in their one-particle phase-space dis-tribution, i.e., E i d3N i,±1 2 dp3 i ...
