Abstract:
The flavor space of particles produced in collider environments contains informative quantum correlations. We present a systematic approach for constructing the complete flavor density matrix for a meson and antimeson system (MM[over ¯]) in the Bloch vector space at a given time t, which can be at or after production. We point out that the B_{s}^{0} and K^{0} systems are superior to the B_{d}^{0} and D^{0} systems for quantum tomography because of their flavor oscillation and decay properties. Performing quantum tomography for the MM[over ¯] system can facilitate the study of production mechanisms, decoherence phenomena, quantum information variables, and potential new sources of CP violation.
