The electromagnetic form factors are fundamental quantities parameterizing the electric and magnetic structure of hadrons. This work estimates the statistical and total accuracy with which the form factors can be measured at PANDA, using an analysis of simulated data within the PandaRoot software framework. The most crucial background channel is (p) over barp -&gt; pi(+)pi(-), due to the very similar behavior of muons and pions in the detector. The suppression factors are evaluated for this and all other relevant background channels at different values of antiproton beam momentum. The signal/background separation is based on a multivariate analysis, using the Boosted Decision Trees method. An expected background subtraction is included in this study, based on realistic angular distributions of the background contribution. Systematic uncertainties are considered and the relative total uncertainties of the form factor measurements are presented.</subfield> </datafield> <datafield tag="650" ind1="1" ind2="7"> <subfield code="2">opendefinition.org</subfield> <subfield code="a">cc-by</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ Politecn Marche Ancona, Ancona, Italy</subfield> <subfield code="a">Davi, F.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ Politecn Marche Ancona, Ancona, Italy</subfield> <subfield code="a">Lancioni, G.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ Politecn Marche Ancona, Ancona, Italy</subfield> <subfield code="a">Mengucci, P.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ Politecn Marche Ancona, Ancona, Italy</subfield> <subfield code="a">Montalto, L.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ Politecn Marche Ancona, Ancona, Italy</subfield> <subfield code="a">Natali, P.
