CSIC ORCID | Fecha de publicación: | 6-sep-2010 | Editor: | Elsevier | Citación: | Physics Letters - Section B 692 (4): 232-239 (2010) | Resumen: | We report on a CDF measurement of the total cross section and rapidity distribution, d sigma/dy, for gamma*/Z -> e(+)e(-) events in the Z boson mass region (66 < M(ee) < 116 GeV/c(2)) produced in p (p) over bar collisions at root s = 1.96 TeV with 2.1 fb(-1) of integrated luminosity. The measured cross section of 257 +/- 16 pb and d sigma/dy distribution are compared with Next-to-Leading-Order (NLO) and Next-to-Next-to-Leading-Order (NNLO) QCD theory predictions with CTEQ and MRST/MSTW parton distribution functions (PDFs). There is good agreement between the experimental total cross section and d sigma/dy measurements with theoretical calculations with the most recent NNLO PDFs. | Descripción: | 8 páginas10 figuras, 3 tablas.-- El Pdf del artículo es la versión pre-print: 0908.3914v4.-- CDF Collaboration: et al. | Versión del editor: | http://dx.doi.org/10.1016/j.physletb.2010.06.043 | URI: | http://hdl.handle.net/10261/42629 | DOI: | 10.1016/j.physletb.2010.06.043 | ISSN: | 0370-2693 |
