    "abstract": "The $s$-ordered phase-sum and phase-difference distributions are considered\nfor Bell-like superpositions of two-mode coherent states. The distributions are\nsensitive, respectively, to the sum and difference of the phases of the\nentangled coherent states. They show loss of information about the entangled\nstate and may take on negative values for some orderings $s$.",
