No. of bitstreams: 0 Previous issue date: 2001-12-13; The σ- mean squared charge radius has been measured in the space-like Q2 range 0.035-0.105 GeV2/c2 by elastic scattering of a σ- beam off atomic electrons. The measurement was performed with the SELEX (E781) spectrometer using the Fermilab hyperon beam at a mean energy of 610 GeV/c. We obtain (rch2σ- = ...
Production asymmetry of Ds from 600 GeV/c σ- and π- beam
Kaya, M.; Alkhazov, G.; Atamantchouk, A. G.; Balatz, M. Y.; Bondar, N. F.; Cooper, P. S.; Dauwe, L. J.; Davidenko, G. V.; Dersch, U.; Dolgolenko, A. G.Made available in DSpace on 2022-04-28T19:55:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2003-04-10; The production of Ds- relative to Ds+ as a function of xF with 600 GeV/c Σ- beam is measured in the interval 0.15 < xF < 0.7 by the SELEX (E781) experiment at Fermilab. The integrated charge asymmetries with 600 GeV/c Σ- beam (0.53 ± 0.06) and π- beam (0.06 ± 0.11) are also compared. The results show th...

Jun, S. Y.; Akchurin, N.; Andreev, V. A.; Atamantchouk, A. G.; Aykac, M.; Balatz, M. Y.; Bondar, N. F.; Bravar, A.; Cooper, P. S.; Dauwe, L. J.Made available in DSpace on 2022-04-28T19:53:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2000-01-01; We report the first observation of the Cabibbo-suppressed charm baryon decay Ξ+c→pK- π+. We observe 150±22±5 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600GeV/c Σ- beam. The branching fractions of the de...

No. of bitstreams: 0 Previous issue date: 2001-12-20; We report a precise measurement of the Ds± meson lifetime. The data were taken by the SELEX experiment (E781) spectrometer using 600 GeV/c ∑-, π- 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 ...
