The absolute branching fractions B(Xi(1530)^- to Xi^0 pi^-) = 61.4% and B(Xi(1530)^- to Xi^- pi^0) = 29.7% are measured for the first time, with their sum 91.1%, and B(psi(3686) to anti-Xi+ Xi(1530)^- + c.c.) is updated to 8.67 x 10^{-6}.

Measurement of the Absolute Branching Fraction of Xi(1530)^{-} to (Xi pi)^{-} and Updated Measurement of the Branching Fraction of psi(3686) to anti-Xi^{+} Xi(1530)^{-} + c.c
The absolute branching fractions B(Xi(1530)^- to Xi^0 pi^-) = 61.4% and B(Xi(1530)^- to Xi^- pi^0) = 29.7% are measured for the first time, with their sum 91.1%, and B(psi(3686) to anti-Xi+ Xi(1530)^- + c.c.) is updated to 8.67 x 10^{-6}.
