چکیده

We present a study of the decay B0(s) --> J/psiphi. We obtain the CP-odd fraction in the final state at time zero, Rperpendicular = 0.16 +/- 0.10(stat) +/- 0.02 (syst), the average lifetime of the (B0(s), B0(s)) system, tau(B0(s)) = 1.39(+0.13)(-0.16)(stat)(+0.01)(-0.02)(syst) ps, and the relative width difference between the heavy and light mass eigenstates, DeltaGamma/Gamma tripple bond (GammaL - GammaH)/Gamma = 0.24(+0.28)(-0.38)(stat)(+0.03)(-0.04)(syst). With the additional constraint from the world average of the lifetime measurements using semileptonic decays, we find tau(B0(s)) = 1.39 +/- 0.06 ps and DeltaGamma/Gamma = 0.25(+0.14)(-0.15). For the ratio of the B0(s) and B0 lifetimes we obtain tau(B0(s))/tau(B0) = 0.91 +/- 0.09(stat) +/- 0.003(syst).

Measurement of the B 0 s Meson Lifetime Using Semileptonic

The lifetime of the B0 s meson is measured using the semileptonic decay B0 s → D s l+νX. The data sample consists of about 110 pb−1 of pp̄ collisions at √ s = 1.8 TeV collected by the CDF detector at Fermilab. Four different D s decay modes are reconstructed resulting in approximately 600 D s l+ signal events. The B0 s meson lifetime is determined to be τ(B0 s ) = (1.36 ± 0.09 +0.06 −0.05) ps, w...

THE MEAN RESIDUAL LIFETIME OF PARALLEL SYSTEMS WITH TWO EXCHANGEABLE COMPONENTS UNDER THE GENERALIZED FARLIE-GUMBEL-MORGENSTERN MODEL

The parallel systems are special important types of coherent structures and have many applications in various areas.In this paper we consider a two-exchangeable-component parallel system for the Generalized Farlie-Gumbel-Morgenstern (Generalized FGM) distribution. We study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...

Measurement of the effective B0s→J/ψK0S lifetime

This paper reports the first measurement of the effective B0 s → J/ψK0 S lifetime and an updated measurement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ eff J/ψK0 S = 1.75 ± 0.12...

Vitellogenin assay by enzyme-linked immunosorbent assay (ELISA) as a biomarker of endocrine disruptor chemicals (EDCs) pollution

There are increasing evidences that show many xenobiotic chemicals (called as endocrine disruptorchemicals EDCs) through interfering with endocrine system, have the capability to induce developmentaland reproductive abnormalities in humans and animals. The yolk protein precursor vitellogenin (VTG) hasproved to be a simple and sensitive biomarker for assessing exposure of fish to EDCs especially...

A Theoretical Prediction of the Bs-Meson Lifetime Difference

We present the results of a quenched lattice calculation of the operator matrix elements relevant for predicting the Bs width difference. Our main result is (∆ΓBs/ΓBs) = (4.7 ± 1.5 ± 1.6) × 10−2, obtained from the ratio of matrix elements R(mb) = 〈B̄0 s |QS |B0 s 〉/〈B̄0 s |QL|B s 〉 = −0.93(3)+0.00 −0.01. R(mb) was evaluated from the two relevant B-parameters BMS S (mb) = 0.86(2) +0.02 −0.03 and B...
