This book was released on 2000 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have performed a measurement of transverse polarization for A baryons produced after the collision of longitudinally polarized electrons and unpolarized positrons at the Z0 resonance. The measurement is based on 560,000 Z0 decays produced at the SLC and collected by the SLD collaboration at SLAC between 1993 and 1998. We define the axis of polarization as the cross product of the thrust axis direction and the [Lambda] momentum and we use the longitudinal polarization of the incoming electrons to sign the thrust axis according to the direction of the color field, thereby testing the Andersson-Gustavson-Ingelman model for [Lambda] transverse polarization. We find that if the mechanism responsible for [Lambda] transverse polarization is completely correlated with the color field direction -0.22% (P[Lambda])[perpendicular]

Download or read book Lambda Polarization in Exclusive Electro and Photoproduction at CLAS written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The CLAS collaboration at JLab has recent results on[Lambda] polarization for both electroproduction and photoproduction of K[sup+][Lambda] exclusive states. I note the striking phenomenological trends in the data and discuss the underlying physics which might give rise to these phenomena; both in the context of an e.ective Lagrangian formalism, where the degrees of freedom are intermediate mesons and baryons, and also in the context of a simple quark picture. The quark model argument leads to the conclusion that the s and[bar s] quarks are produced with spins anti-aligned, in apparent contradiction to the popular[sup 3]P[sub 0] model of quark pair creation in which the pair is created with vacuum quantum numbers (J=0 and positive parity), i.e. in an S=1, L=1, J=0 angular momentum state.

Available in PDF, EPUB and Kindle. Book excerpt: I present recent results from the CLAS collaboration on Lambda and Sigma^0 polarization for both electroproduction and photoproduction of K^+Lambda and K^+Sigma^0 exclusive states. I interpret these data using a simple quark model, leading to the surprising conclusion that the s and s(pol) quarks are produced with spins anti-aligned, in apparent contradiction to the popular ^3P_0 model of quark pair creation.

Download or read book Physics at the Terascale written by Ian Brock and published by John Wiley & Sons. This book was released on 2011-05-04 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by authors working at the forefront of research, this accessible treatment presents the current status of the field of collider-based particle physics at the highest energies available, as well as recent results and experimental techniques. It is clearly divided into three sections; The first covers the physics -- discussing the various aspects of the Standard Model as well as its extensions, explaining important experimental results and highlighting the expectations from the Large Hadron Collider (LHC). The second is dedicated to the involved technologies and detector concepts, and the third covers the important - but often neglected - topics of the organisation and financing of high-energy physics research. A useful resource for students and researchers from high-energy physics.
Download or read book The Physics of the B Factories written by Adrian Bevan and published by Springer. This book was released on 2015-03-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive work thoroughly introduces and reviews the set of results from Belle and BaBar - after more than two decades of independent and complementary work - all the way from the detectors and the analysis tools used, up to the physics results, and the interpretation of these results. The world’s two giant B Factory collaborations, Belle at KEK and BaBar at SLAC, have successfully completed their main mission to discover and quantify CP violation in the decays of B mesons. CP violation is a necessary requirement to distinguish unambiguously between matter and antimatter. The shared primary objective of the two B Factory experiments was to determine the shape of the so-called unitarity triangle, an abstract triangle representing interactions of quarks, the elementary constituents of matter. The area of the triangle is a measure of the amount of CP violation associated with the weak force. Many other measurements have been performed by the B Factories and are also discussed in this work.
Download or read book String Theory and the Real World written by Gordon Kane and published by Morgan & Claypool Publishers. This book was released on 2017-03-27 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to explain why 'string theory' may provide the comprehensive underlying theory that describes and explains our world. It is an enthusiastic view of how compactified string/M-theories (plus data that may be reachable) seem to have the possibilities of leading to a comprehensive underlying theory of particle physics and cosmology, perhaps soon. We are living in a hugely exciting era for science, one during which it may be possible to achieve a real and true understanding of our physical world.
