X(3872) in Effective Field Theory

Original · EN

If the X(3872) resonance is a shallow boundstate of a the charm mesons D⁰ D*⁰ and D*⁰ D⁰, it can be described by an effective theory of nonrelativistic D mesons coupled to nonrelativistic pions (X-EFT). In this talk, I give a brief overview of the X(3872), followed by a short review of X-EFT. I end my talk with results from calculations of the next-to-leading-order correction to the partial decay width Γ[X→ D⁰ D⁰ π⁰], and the decay of X(3872) to P-wave quarkonia.
