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                                                $$ \mathcal{O} $$                                      O                                                              (              p              6              ).</dc:description><dc:publisher/><dc:date>2022-11-01</dc:date><dc:nsf_par_id>10447112</dc:nsf_par_id><dc:journal_name>Journal of High Energy Physics</dc:journal_name><dc:journal_volume>2022</dc:journal_volume><dc:journal_issue>11</dc:journal_issue><dc:page_range_or_elocation/><dc:issn>1029-8479</dc:issn><dc:isbn/><dc:doi>https://doi.org/10.1007/JHEP11(2022)011</dc:doi><dcq:identifierAwardId>1806430</dcq:identifierAwardId><dc:subject/><dc:version_number/><dc:location/><dc:rights/><dc:institution/><dc:sponsoring_org>National Science Foundation</dc:sponsoring_org></record></records></rdf:RDF>
