1 Jun 2001 | | Journal: | Phys.Lett. B523 (2001) 22-28 | | Subject: | hep-ex | | Affiliation: | SELEX Collaboration | | Abstract: | We report precise measurement of the Ds meson lifetime. The data were taken by the SELEX experiment (E781) spectrometer using 600 GeV/c Sigma-, pi- and p beams. The measurement has been done using 918 reconstructed Ds. The lifetime of the Ds is measured to be 472.5 +- 17.2 +- 6.6 fs, using K*(892)0K+- and phi pi+- decay modes. The lifetime ratio of Ds to D0 is 1.145+-0.049. | | Source: | arXiv, hep-ex/0106005 | | Services: | Forum | Review | PDF | Favorites | |
