Measurement of the branching fractions of the decays D+ -> K-K+K+, D+ -> pi-pi(+) K+ and D-s(+) -> pi-K+K+ [PDF]

open access: yes, 2019
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 K- π+ S-wave from the D+ → K- π+ π+ decay

open access: yes, 2009
Using data from FOCUS (E831) experiment at Fermilab, we present a model independent partial-wave analysis of the K- π+ S-wave amplitude from the decay D+ → K- π+ π+.

Search for hadronic decays of feebly-interacting particles at NA62

open access: yesEuropean Physical Journal C: Particles and Fields
The NA62 experiment at CERN has the capability to collect data in a beam-dump mode, where 400 GeV protons are dumped on an absorber. In this configuration, New Physics particles, including dark photons, dark scalars, and axion-like particles, may be ...

Branching ratios of the decays D0->anti(K)0 K0 and D0 → K(S)0 K(S)0 K(S)0

open access: yes, 1994
The branching ratios of D0->anti(K0) (K0) and D0 → K(s)0 K(s)0 K(s)0 relative to D0->anti(K0) pi+ pi- are reported. The data were accumulated in the 1990–1991 fixed target running period of the Fermilab high energy photoproduction experiment E687.
