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 [...] form factors. On the other hand, the 4-body decay is an important contributor to the future global analysis due to its angular distributions that probe complementary combinations of Wilson coefficients, and …
