Measurement of the branching fractions of the decays D + → K − K + K + , D + → π − π + K + and D s+ → π − K + K +

The branching fractions of the doubly Cabibbo-suppressed decays D+ → K−K+K+, D+ → π−π+K+ and D +s → π−K+K+ are measured using the decays D+ → K−π+π+ and D +s → K−K+π+ as normalisation channels. The measurements are performed using proton-proton collision data collected with the LHCb detector at a ce...

Descripción
Sumario:The branching fractions of the doubly Cabibbo-suppressed decays D+ → K−K+K+, D+ → π−π+K+ and D +s → π−K+K+ are measured using the decays D+ → K−π+π+ and D +s → K−K+π+ as normalisation channels. The measurements are performed using proton-proton collision data collected with the LHCb detector at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 2.0 fb−1.
