This book was released on 2013 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a measurement of the lifetime of the B± c meson in an exclusive decay channel B± c 2!J/ [psi] [pi]±, where the J/[psi] decays as J/[psi] 2![mu]+[mu]- The measurement uses a data sample with an integrated luminosity of 6.7 fb-1 collected at CDF. This is the first measurement of the B± c meson lifetime in a hadronic channel and the measured lifetime, [tau] = 0.449 +0.054 -0.048(stat:) ± 0.019(syst:) ps, is in good agreement with previous results obtained from semileptonic decay channel and confirms previous measurements and theoretical predictions.

Download or read book Measurement of B0 and B+ Lifetimes Using Semileptonic Decays at CDF. written by and published by . This book was released on 2010 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lifetime measurements for B0 and B+ are presented using semileptonic decays of B mesons from 360 pb-1 of data collected by CDF's lepton plus displaced track trigger. The decays B 2!l[nu]DX, where D is either D +, D0, or D* +, are partially reconstructed from a muon or electron, a displaced track, and a fully reconstructed charm meson. The B 0 and B+ lifetimes are obtained from an unbinned maximum-likelihood fit to the proper decay length distributions. The measured lifetimes are [tau]B 0 = 1.527 ± 0.012(stat.) ± 0.023(syst.)ps and [tau]B + = 1.629 ± 0.013(stat.) ± 0.025(syst.)ps.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The lifetime of the B[sub s][sup 0] meson is measured using the semileptonic decay B[sub s][sup 0][r-arrow] D[sub s][sup[minus]]l[sup[plus]][nu]X. The data sample consists of approximately 110 pb[sup[minus]1] of p[ovr p] collisions at[radical]s= 1.8 TeV collected by the CDF detector at the Fermilab Tevatron collider. There are 254[plus-minus]21 D[sub s][sup[minus]]l[sup[plus]] signal events where the D[sub s][sup[plus]] is reconstructed through its decay mode D[sub s][sup[minus]][r-arrow][phi][pi][sup[minus]], [phi][r-arrow] K[sup[plus]]K[sup[minus]]. Using these events, the B[sub s][sup 0] meson lifetime is determined to be[tau](B[sub s][sup 0])[equals] 1.37[sup[plus]0.14][sub[minus]0.12](stat.)[plus-minus]0.04(syst.) ps. The B[sub s][sup 0] meson proper decay length distribution has been examined for a lifetime difference between the two CP eigenstates of the B[sub s][sup 0] meson, B[sub s][sup H] and B[sub s][sup L]. 12 refs., 3 figs., 1 tab.

Book excerpt: The authors report a measurement of the B{sub s}° lifetime in the semileptonic decay channel B{sub s}° → D{sub s}−??X (and its charge conjugate), using approximately 0.4 fb−1 of data collected with the D0 detector during 2002-2004. They have reconstructed 5176 D{sub s}−?+ signal events, where the D{sub s}− is identified via the decay D{sub s}° →??−, followed by? → K+K−. Using these events, they have measured the B{sub s}° lifetime to be?(B{sub s}°) = 1.398 ± 0.044 (stat){sub -0.025}{sup +0.028}(syst) ps. This is the most precise measurement of the B{sub s}° lifetime to date.

Book excerpt: The neutral B meson lifetime has been measured with the data collected by the BABAR detector at the PEP-II storage ring during the year 2000 for a total integrated luminosity of 20.3 fb[sup -1]. The B[sup 0][yields] D*[sup -][pi][sup+] decays have been selected with a partial reconstruction method in which only the fast pion from the B[sup 0] decay and the slow pion from D*[sup -][yields][bar D][sup 0][pi][sup -] are reconstructed. The B[sup 0] lifetime has been measured to be 1.510[+-] 0.040[+-] 0.038 ps with a sample of 6971[+-] 241 reconstructed signal events.

Download or read book Measurement of the B and B° Lifetimes at CDF written by and published by . This book was released on 1995 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two measurements of the lifetime of neutral and charged B mesons in p{bar p} collisions at √s = 1.8 TeV by the CDF experiment are presented. The first relies on the study of exclusive decays of the type B → [psi] K, the second on semileptonic decays of a B meson into a D° or a D. The combined results are [tau](B+) = 1.62 ± 0.09 ps, [tau](B0) = 1.60 ± 0.09 ps and [tau](B+)/[tau](B°) = 1.00 ± 0.07.
