Title: Measurement of the Branching Fraction B(Λ + c→pK -π +)

Abstract

We present the first model-independent measurement of the absolute branching fraction of the Λ + c→pK -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. The branching fraction is measured to be B(Λ + c→pK -π +)=(6.84±0.24 +0.21 -0.27)%, where the first and second uncertainties are statistical and systematic, respectively.
