abstract="The Xi(++)(cc) -> Xi({\textquoteright}+)(c)pi(+) decay is observed using proton-proton collisions collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb(-1). The Xi(++)(cc) -> Xi({\textquoteright}+)(c)pi(+) decay is reconstructed partially, where the photon from the Xi({\textquoteright}+)(c) -> Xi(+)(c)gamma decay is not reconstructed and the pK(-)pi(+) final state of the Sc+ baryon is employed. The Xi(++)(cc) -> Xi({\textquoteright}+)(c)pi(+) branching fraction relative to that of the Xi(++)(cc) -> Xi({\textquoteright}+)(c)pi(+) decay is measured to be 1.41 +/- 0.17 +/- 0.10, where the first uncertainty is statistical and the second systematic.",
