Título: | Dalitz plot analysis of D-s(+)->pi(+)pi(-)pi(+) |
Autor: | Babar Collaboration; Azzolini, Virginia; López-March, Neus CSIC; Martínez-Vidal, Fernando CSIC ORCID; Milanés, Diego A. CSIC ORCID; Oyanguren, Arantza CSIC ORCID; Aubert, B. | Fecha de publicación: | 9-feb-2009 | Editor: | American Physical Society | Citación: | Physical Review - Section D - Particles and Fields 79 (3): 032003 (2009) | Resumen: | A Dalitz plot analysis of approximately 13 000 D-s(+) decays to pi(+)pi(-)pi(+) has been performed. The analysis uses a 384 fb(-1) data sample recorded by the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring running at center of mass energies near 10.6 GeV. Amplitudes and phases of the intermediate resonances which contribute to this final state are measured. A high precision measurement of the ratio of branching fractions is performed: B(D-s(+)->pi(+)pi(-)pi(+))/B(D-s(+)-> K+K-pi(+))=0.199 +/- 0.004 +/- 0.009. Using a model-independent partial wave analysis, the amplitude and phase of the S wave have been measured. | Versión del editor: | http://dx.doi.org/ 10.1103/PhysRevD.79.032003 | URI: | http://hdl.handle.net/10261/22023 | DOI: | 10.1103/PhysRevD.79.032003 | ISSN: | 1550-7998 |
