Available in PDF, EPUB and Kindle. Book excerpt: The average b-hadron lifetime has been measured using a high statistics sample of[ital B][r-arrow][ital J]/[psi][Chi] decays recorded with the Collider Detector at Fermilab. We use a sample with an integrated luminosity of[approx] 90[ital pb][sup -1] recorded during the 1994-95 running period. The decay vertices of[approx] 62656 inclusive[ital J]/[psi][r-arrow][mu][sup+][mu][sup -] candidates have been reconstructed using information from a silicon vertex-detector. The measured[ital B]lifetime, which is the average over all b-hadrons produced in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV weighted by their branching ratios into[ital J]/[psi], is 1.524[+-] 0.015 ([ital stat])[sup+0.035][sub -0.026] ([ital sys]) ps. The precision of this measurement is significantly improved compared to the inclusive lifetime measurement published previously using[approx] 10[ital pb][sup -1].

Download or read book A Preliminary Measurement of the Average B Hadron Lifetime written by and published by . This book was released on 1994 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average B hadron lifetime was measured using data collected with the SLD detector at the SLC in 1993. From a sample of -50,000 Z° events, a sample enriched in Z° → b{bar b} was selected by applying an impact parameter tag. The lifetime was extracted from the decay length distribution of inclusive vertices reconstructed in three dimensions. A binned maximum likelihood method yielded an average B hadron lifetime of?{sub B} = 1.577±0.032(stat.)±0.046(syst.) ps.

Book excerpt: Data from ee− collisions collected by the MAC detector at the SLAC storage ring PEP with a new vertex chamber having position resolution of 50 .mu.m have been analyzed with a new method to make a determination of the lifetime of hadrons containing b-quarks. In addition, data collected with MAC before the vertex chamber was installed have been re-analyzed using the new method. The combined result for the B lifetime is tau/sub b/ = (1.16 +- 0.16(stat.) +- 0.07(syst.)ps) x (1 +- 0.15), where the last factor is the scale. 12 refs., 2 figs.

Download or read book B-lifetime Measurements at the Tevatron written by and published by . This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the run period from May 1992 to begin of June 1993 the Collider Detector at Fermilab (CDF) has recorded ≈ 21.4 pb−1 of p{anti p} collider data at √s = 1.8 TeV. For this run the detector had been upgraded which significantly enhanced its b-physics capabilities. The upgrades include a high precision Silicon VerteX detector (SVX) which enables CDF to reconstruct the decay vertex and decay length of b-hadrons. In this article the author reports on several measurements of the lifetime of b-flavored hadrons. The determination of the average b-lifetime using inclusive J/??s, the measurement of the B{sup {+-}} and B° lifetimes by reconstructing exclusive final states including a J/? or?(2S) and a measurement of the B{sub s}° meson lifetime exploiting the decay: B{sub s} → l?D{sub s} → l???+ → l?K+K−?+.

Download or read book B-lifetime Measurements at CDF. written by and published by . This book was released on 1993 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average b-hadron lifetime has been measured using a high statistics sample of B → J/?X decays recorded with the Collider Detector at Fermilab. The decay vertices of J/? →??− candidates have been reconstructed using information from a silicon vertex-detector. The measured B lifetime, which is the average over all b-hadrons produced in p{bar p} collisions at √s = 1.8 TeV, weighted by their branching ratios into J/? is:?B = 1.46 ± 0.06(stat.) ± 0.06(sys.)ps (preliminary); In addition we used the fully reconstructed final states B{sup ±} → J/?K{sup ±} and B° → J/?K°* to measure the exclusive lifetime of charged and neutral B-mesons. We measure:?{sub B}{sup ±} = 1.59 ± 0.27(stat.) ± 0.17(sys.) ps (preliminary);?{sub B}° = 1. 34 ± 0.31 (stat.) {plus_minus} 0.17 (sys.) ps (preliminary); From this we obtain the following result for the lifetime ratio:?{sub B}{sup {plus_minus}}/? {sub B}° = 1.19 {plus_minus} 0.35(stat.) {plus_minus} 0.12(sys.) (preliminary); This represents the first measurements of the b-lifetime at a hadron collider.
