Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays
perform a global analysis of |Δ c |=|Δ u |=1 transitions using recent data on D 0→ μ + μ −, D +→ π + μ + μ −, Λ c → p μ + μ −, and D 0→ π + π − μ + μ − decays, and work out constraints on new physics Wilson [...] test observables, not probed with searches in other sectors such as kaon and b -decays. The decay D 0→ π + π − μ + μ − requires better understanding of hadronic contributions to be competitive in the current …
