Evidence for X(3872)--> psi (2S) gamma in B±-->X(3872)K± Decays and a Study of B-->cc-bar gamma K

In a search for B→cc̅ γK decays with the BABAR detector, where cc̅ includes J/ψ and ψ(2S), and K includes K±, K[supscript S] [superscript 0], and K*(892), we find evidence for X(3872)→J/ψγ and X(3872)→ψ(2S)γ with 3.6σ and 3.5σ significance, respectively. We measure the product of branching fraction...
