Abstract
Three recent results on charm physics are presented based on Run II data using the Fermilab Tevatron Collider. The DØ collaboration reports preliminary results on the first observation of the rare decay , ϕ→μ+μ−, a measurement of the branching fraction for D± to the same final state, and an upper limit for the non-resonant decay D±→π±μ+μ−. The CDF collaboration reports a preliminary measurement of the angular distribution for X(3872)→J/ψπ+π− and restricts the X(3872) quantum numbers to JPC=1++ or 2−+. Also, CDF reports a measurement of the ratio of branching fractions of the rare (doubly Cabibbo-suppressed) decay D0→K+π− and the Cabibbo-favored decay D0→K−π+ (and charge conjugate decays).
