Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays
Abstracts: We perform a global analysis of |Δc|=|Δu|=1 transitions using recent data on D0→μ+μ- , D+→π+μ+μ- , Λc→pμ+μ- , and D0→π+π-μ+μ- decays, and work out constraints on new physics Wilson coefficients ( ′)7 [...] test observables, not probed with searches in other sectors such as kaon and b-decays . The decay D0→π+π-μ+μ- requires better understanding of hadronic contributions to be competitive in the current fit …
