Download or read book Evidence for Spin Correlation in $t\bar{t}$ Production written by and published by . This book was released on 2011 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the ratio of events with correlated t and {bar t} spins to the total number of t{bar t} events. This ratio f is evaluated using a matrix-element-based approach in events with a single lepton (electron or muon) and at least four jets. We analyze p{bar p} collisions data corresponding to an integrated luminosity of 5.3 fb−1 collected with the D0 detector at the Fermilab Tevatron collider operating at a center of mass energy √s = 1.96 TeV. Combining this result with a recent measurement of f in t{bar t} → W+b W−{bar b} → l+ [nu]b l− {bar {nu}}b final states, we find f in agreement with the standard model. In addition, the combination provides evidence for the presence of spin correlation in t{bar t} events with a significance of more than three standard deviations.

Book excerpt: We present a measurement of the ratio of events with correlated t and t spins to the total number of tt events. This ratio f is evaluated using a matrix-element-based approach in 729 tt candidate events with a single lepton l (electron or muon) and at least four jets. The analyzed pp collisions data correspond to an integrated luminosity of 5.3 fb-1 and were collected with the D0 detector at the Fermilab Tevatron collider operating at a center-of-mass energy \(\sqrt{s}=1.96\) TeV. Combining this result with a recent measurement of f in dileptonic final states, we find f in agreement with the standard model. In addition, the combination provides evidence for the presence of spin correlation in tt events with a significance of more than 3 standard deviations.

Book Synopsis Measurement of Spin Correlations in T-tbar Production Using the Matrix Element Method in the Muon+jets Final State in Pp Collisions at {u221A}(s) by :
Download or read book Measurement of Spin Correlations in T-tbar Production Using the Matrix Element Method in the Muon+jets Final State in Pp Collisions at {u221A}(s) written by and published by . This book was released on 2016 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consistency of the spin correlation strength in top quark pair production with the standard model (SM) prediction is tested in the muon+jets final state. The events are selected from pp collisions, collected by the CMS detector, at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb-1. We then compare the data with the expectation for the spin correlation predicted by the SM and with the expectation of no correlation. Furthermore, by using a template fit method, the fraction of events that show SM spin correlations is measured to be 0.72 ±0.08 (stat)+0.15 -0.13 (syst), representing the most precise measurement of this quantity in the lepton+jets final state to date.

Book excerpt: In a new branch of physics and technology, called spin-electronics or spintronics, the flow of electrical charge (usual current) as well as the flow of electron spin, the so-called "spin current", are manipulated and controlled together. This book is intended to provide an introduction and guide to the new physics and applications of spin current.

Download or read book Plastics Additives written by J.C.J. Bart and published by IOS Press. This book was released on 2006-03-15 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cover-to-cover reading of Plastics Additives, Advanced Industrial Analysis, is recommended for both professional analysts and plastics technologists. Professor Bart’s prose style is easy to read. A professional background in analytical chemistry is not assumed. Particularly valuable is the trove of good advice as to which approach might be best in a given situation. Every department with a serious interest in additive / property relations should invest in a copy.” -- PMAD Newsletter. This industrially relevant and up-to-date resource deals with all established and emerging analytical methods for in-polymer additive analysis of plastics formulations. Quality assurance and industrial troubleshooting all benefit from direct analysis modes. Plastics Additives comprises detailed coverage of solid-state spectroscopy, thermal analysis and pyrolysis, laser techniques, surface studies and microanalysis along with process analytics, quantitative analysis and modern method development and validation applied to additives in polymers. The book is organised for quick and easy reference and is extensively illustrated with over 200 figures, 300 flow diagrams and tables to facilitate rapid understanding of this topic, and it contains 4000 references. Emphasis is on understanding (principles and characteristics) and industrial applicability.

Book Synopsis Statistical Mechanics by : James Sethna
Download or read book Statistical Mechanics written by James Sethna and published by OUP Oxford. This book was released on 2006-04-07 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: In each generation, scientists must redefine their fields: abstracting, simplifying and distilling the previous standard topics to make room for new advances and methods. Sethna's book takes this step for statistical mechanics - a field rooted in physics and chemistry whose ideas and methods are now central to information theory, complexity, and modern biology. Aimed at advanced undergraduates and early graduate students in all of these fields, Sethna limits his main presentation to the topics that future mathematicians and biologists, as well as physicists and chemists, will find fascinating and central to their work. The amazing breadth of the field is reflected in the author's large supply of carefully crafted exercises, each an introduction to a whole field of study: everything from chaos through information theory to life at the end of the universe.
