The model-independent branching fraction is measured to be (9<jats:italic>.</jats:italic>15 ± 0<jats:italic>.</jats:italic>08) × 10<jats:sup><jats:italic>−</jats:italic>8</jats:sup>, a factor three more precise than previous measurements. The decay form factor is presented as a function of the squared dimuon mass. A measurement of the form factor parameters and their uncertainties is performed using a description based on Chiral Perturbation Theory at <jats:inline-formula><jats:alternatives><jats:tex-math>$$ \mathcal{O} $$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML">
