 LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13 TeV
1  Measured in restricted phase space with m( ${{\mathit K}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ) $<$ $1950$ MeV, m( ${{\mathit K}^{+}}{{\mathit \pi}^{-}}$ ) $<$ $1200$ MeV and m( ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ) $<$ $1200$ MeV. The value is modulo 180$^\circ{}$.
2  A model-independent coherence factor for the decay ${{\mathit B}_{{s}}}$ $\rightarrow$ ${{\mathit D}_{{s}}}{{\mathit K}}{{\mathit \pi}}{{\mathit \pi}}$ (in the restricted phase space region) is also reported.
