Measurement of the Branching Fraction B ( Λ c + → p K − π + )
A. Zupanc, C. Bartel, N. Gabyshev, I. Adachi et autres
We present the first model-independent measurement of the absolute branching fraction of the ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}\ensuremath{\rightarrow}p{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ decay using a data sample of $978\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. The number of ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}$ baryons is determined by …
