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

In a search for B→cc̄γK decays with the BABAR detector, where cc̄ includes J/ψ and ψ(2S), and K includes K±, KS0, 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 fractions B(B±→ X(3872)K±)×B(X(3872)→...
