Determination of V ub at the Z – boson resonance

چکیده
We show that the observation of energetic charged leptons from semileptonic b becays at the LEP and SLC Z–boson factories offers a unique opportunity to measure the quark mixing matrix element V ub. We present various distributions of the b decay products to show that the b → u decays can be cleanly separated from the b → c decays, with a signal of O(100) events per million Z bosons produced.

The Z Boson
Precision measurements at the Z-boson resonance using electron{positron colliding beams began in 1989 at the SLC and at LEP. During 1989{95, the four CERN experiments made high-statistics studies of the Z. The availability of longitudinally polarized electron beams at the SLC since 1993 enabled a precision determination of the eeective electroweak mixing angle sin 2 W that is competitive with t...

We consider the possibility of Higgs boson detection at LEP II under the resonance threshold (√ s < m H + m Z) in the framework of complete tree level approach to the calculation of the e + e − → ν ¯ νb ¯ b amplitude, simulating b-quark fragmentation to hadrons and taking into account typical detector properties. At the energy below the 2m Z threshold √ s = 175 GeV Higgs boson production under ...
متن کاملZt and γt production via top flavour - changing neutral couplings at the Fermilab Tevatron
Associated single top production with a Z boson or a photon at large hadron colliders provides a precise determination of top flavour-changing neutral couplings. The best way to measure these couplings with the up quark at Tevatron is to search for events with three jets and missing energy or events with a pho-ton, a charged lepton, a jet and missing energy. The other significant decay channels...
متن کاملDetermination of |v Ub |
The element V ub of the CKM mixing matrix is the smallest of the quark couplings and is crucial in understanding CP violation in the B system. In this review, we discuss the present status of the determination of its magnitude, which involves a significant effort both experimentally and theoretically. Decisive progress has been achieved in recent years, thanks in part to the large data sets tha...
متن کاملDetermination of Resonance Frequency of Dominant and Higher Order Modes in Thin and Thick Circular Microstrip Patch Antennas with Superstrate by MWM (RESEARCH NOTE)
An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...
