A simple and robust method to measure Xi(c) and Xi(b) polarizations
The polarizations of the @g states produced in high energy collisions can be derived from the dilepton decay distributions of the daughter J/@j or @? mesons, with a reduced dependence of the measurement on the details of photon reconstruction and simulation, and eliminating the dependence of the pol...

| Sumario: | The polarizations of the @g states produced in high energy collisions can be derived from the dilepton decay distributions of the daughter J/@j or @? mesons, with a reduced dependence of the measurement on the details of photon reconstruction and simulation, and eliminating the dependence of the polarization measurement on the actual details of the multipole structure of the radiative transition. |
