In this work, we present the first model-independent measurement of the absolute branching fraction of the Λ c + p K - π + decay using a data sample of 978 fb - 1 collected with the Belle detector at the KEKB asymmetric-energy e + e - collider. The number of Λ c + baryons is determined by reconstructing the recoiling D ( * ) - p ¯ π + system in events of the type e + e - D ( * ) - p ¯ π + Λ c + . Lastly, the branching fraction is measured to be B ( Λ c + p K - π + ) = ( 6.84 ± 0.24 - 0.27 + 0.21 ) % , where the first and second uncertainties are statistical and systematic, respectively.
