The First Gauge Theory of Weak Interactions and the Prediction of Weak Neutral Currents
The three theoretical and historical components of the Standard Model are the exact chiral gauge theory of weak interactions, electroweak unification, and the Higgs mechanism for spontaneous symmetry breaking. I put into historical perspective my 1958 invention of the first gauge theory of weak interactions, predicting weak neutral currents, and show how the fundamental differences between glob...
متن کاملFive Phases of Weak Neutral Current Experiments from the Perspective of a Theorist
I give my personal perspective on the past, present, and future of weak neutral current experiments, emphasizing the experimental inputs; the theoretical difficulties and inputs; the role of model independent and global analyses; and the implications at each stage. • Introductory Comments • The Discovery Phase (unification) • The Second Generation (the standard model confirmed) • The Third Gene...
متن کاملWEAK NEUTRAL CURRENTS IN e + -
The differential cross section of e+e--) F+F(F+=p+, p, 1;‘, etc.) is calculated for arbitrarily polarized incident and outgoing beams by exchanging one photon and one neutral Z-meson coupled to neutral weak currents. The interference effects manifest themselves in significant parity violating asymmetries for longitudinal polarizations which are about 4(4.5)0/o at q=28 GeV, 9(12.5)% at q=40 GeV ...
متن کاملapplying transitivity theory to gender analysis of efl textbook: : a comparative study.
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
15 صفحه اولNeutral theory: a historical perspective.
To resolve a panselectionist paradox, the population geneticist Kimura invented a neutral theory, where each gene is equally likely to enter the next generation whatever its allelic type. To learn what could be explained without invoking Darwinian adaptive divergence, Hubbell devised a similar neutral theory for forest ecology, assuming each tree is equally likely to reproduce whatever its spec...
