Download or read book B Mixing and Lifetime Measurements with the BaBar Detector written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent BABAR measurements on lifetime and mixing of B mesons are reported. Various techniques are used, ranging from the full reconstruction of hadronic B decays, to partial reconstruction techniques, and to a totally inclusive approach with dilepton events. The results presented are based on a data sample collected by BABAR during the 1999-2000 data taking, and should be considered as preliminary.

Book excerpt: The BABAR experiment at the PEP-II asymmetric B factory at SLAC has collected a large sample of data at the[Upsilon](4S) resonance. I will summarize BABAR's new results on CP violation, B mixing and lifetimes, and a selection of rare B decays. In particular, I will describe in detail the measurement of the CP violating parameter sin2[beta]; BABAR has observed CP violation in the neutral B system finding sin2[beta]= 0.59[+-] 0.14[+-] 0.05.

Book excerpt: The Tevatron experiments, CDF and D0, have produced a wealth of new B-physics results since the start of Run II in 2001. We've observed new B-hadrons, seen new effects, and increased many-fold the precision with which we know the properties of b-quark systems. In these proceedings, we will discuss two of the most fruitful areas in the Tevatron B-physics program: lifetimes and mixing. We'll examine the experimental issues driving these analyses, present a summary of the latest results, and discuss prospects for the future.

Available in PDF, EPUB and Kindle. Book excerpt: The Belle experiment is located in the KEK research centre (Japan) and is primarily devoted to the study of CP violation in the B meson sector. Belle is placed on the KEKB collider, one of the two currently running "B-meson factories", which produce Banti-B pairs. KEKB has created more than 150 million pairs in total, a world record for this kind of colliders. This large sample allows very precise measurements in the physics of beauty mesons. The present analysis falls within the framework of these precise measurements. One of the most remarkable phenomena in high-energy physics is the ability of weak interactions to couple a neutral meson to its anti-meson. In this work, we study the coupling of neutral B with neutral anti-B meson, which induces an oscillation of frequency _md we can measure accurately. Besides the interest of this phenomenon itself, this measurement plays an important role in the quest for the origin of CP violation. The standard model of electro-weak interactions does not include CP violation in a fully satisfactory way. The search for yet unexplained physical phenomena is, therefore, the main motivation of the Belle collaboration. Many measurements of _md have previously been performed. The present work, however, leads to a precision on _md that was never reached before. This is the result of the excellent performance of KEKB, and of an original approach that allows to considerably reduce background contamination of pertinent events. This approach was already successfully used by other collaborations, in slightly different conditions as here. The method we employed consists in the partial reconstruction of one of the B mesons through the decay channel ___D*(D0_)l_l, where only the information on the lepton l and the pion _ are used. The information on the other B meson of the initial Banti-B pair is extracted from a single high-energy lepton. The available sample of Banti-B pairs thus does not suffer from large reductions due to complete reconst.
