  • For complete list of authors see http://dx.doi.org/10.1007/JHEP07(2022)051Title in Web of Sience: Amplitude analysis and branching fraction measurement of D-s(+) -> K-K+pi(+)pi(+)pi(-)
  • Using e(+)e(-) annihilation data corresponding to a total integrated luminosity of 6.32 fb(-1) collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BE- SIII detector, we perform an amplitude analysis of the decay D-s(+) -> K-K+pi(+)pi(+)pi(-) and de-termine the relative fractions and phases of different intermediate processes. Absolute branch- ing fraction of D-s(+) -> K-K+pi(+)pi(+)pi(-) decay is measured to be (6.60 +/- 0.47(stat). +/- 0.38(syst).) x 10(-3). The dominant intermediate process is D-s(+) -> a(1) (1260)(+)phi,phi -> K- K+, a(1)(1260)(+) -> rho pi(+), rho -> pi(+)pi(-), with a branching fraction of (5.15 +/- 0.41(stat.) +/- 0.32(syst.)) x 10(-3).
