Eschrich, I.; Krüger, H.; Simon, J.; Vorwalter, K.; Alkhazov, G.; Atamantchouk, A. G.; Balatz, M. Y.; Bondar, N. F.; Cooper, P. S.; Dauwe, L. J.Made available in DSpace on 2022-04-28T19:55:23Z (GMT). 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...

No. of bitstreams: 0 Previous issue date: 2000-07-17; Total cross sections for Σ- and π- on beryllium, carbon, polyethylene and copper as well as total cross sections for protons on beryllium and carbon have been measured in a broad momentum range around 600GeV/c . These measurements were performed with a transmission technique in the SELEX hyperon-beam ex...
Observation of the cabibbo-suppressed decay Ξ+c→pK- π+
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...

Thomas, G. P.; Gülmez, E.; Edelstein, R.; Jun, S. Y.; Kulyavtsev, A. I.; Kushnirenko, A.; Mathew, P.; Mattson, M.; Procario, M.; Russ, J.Made available in DSpace on 2022-04-29T07:53:44Z (GMT). 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 ...
Epigenome-wide DNA methylation profiling of periprostatic adipose tissue in pro...
Cheng, Y.; Monteiro, C.; Matos, A.; You, J.; Fraga, A.; Pereira, C.; Catalán, V.; Rodríguez, A.; Gómez-Ambrosi, J.; Frühbeck, G.; Ribeiro, R.; Hu, P.Background: Periprostatic adipose tissue (PPAT) has been recognized to associate with prostate cancer (PCa) aggressiveness and progression. Here, we sought to investigate whether excess adiposity modulates the methylome of PPAT in PCa patients. DNA methylation profiling was performed in PPAT from obese/overweight (OB/OW, BMI > 25 kg m-2) and normal weight (NW, BMI < 25 kg m-2) PCa patients. Significant differen...
