This book was released on 2016-11-26 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong Interactions in Spacelike and Timelike Domains: Dispersive Approach provides the theoretical basis for the description of the strong interactions in the spacelike and timelike domains. The book primarily focuses on the hadronic vacuum polarization function, R-ratio of electron-positron annihilation into hadrons, and the Adler function, which govern a variety of the strong interaction processes at various energy scales. Specifically, the book presents the essentials of the dispersion relations for these functions, recaps their perturbative calculation, and delineates the dispersively improved perturbation theory. The book also elucidates the peculiarities of the continuation of the spacelike perturbative results into the timelike domain, which is indispensable for the studies of electron-positron annihilation into hadrons and the related processes. - Covers the topics that play an essential role in contemporary particle physics and future collider projects - Applicable for self-education alongside standard textbooks - Makes the subject easily accessible without the need of an extensive theoretical background

Download or read book Gribov 90 Memorial Volume Field Theory Symmetry And Related Topics Proceedings Of The Memorial Workshop Devoted To The 90th Birthday Of V N Gribov written by Yuri L Dokshitzer and published by World Scientific. This book was released on 2021-04-20 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vladimir Naumovich Gribov is one of the creators of modern theoretical physics. The concepts and methods that Gribov has developed in the second half of the 20th century became cornerstones of the physics of high energy hadron interactions (relativistic theory of complex angular momenta, a notion of the vacuum pole — Pomeron, effective reggeon field theory), condensed matter physics (critical phenomena), neutrino oscillations, and nuclear physics.His unmatched insights into the nature of the quantum field theory helped to elucidate, in particular, the origin of classical solutions (instantons), quantum anomalies, specific problems in quantization of non-Abelian fields (Gribov anomalies, Gribov horizon), and the role of light quarks in the color confinement phenomenon.The Memorial Workshop devoted to Gribov's 90th birthday was cancelled due to the coronavirus pandemic in 2020; however, this did not deter the collection of many new studies in challenging theoretical physics problems across a broad variety of topics, and shared memories about their colleague, great teacher and friend. The contributions of this memorial volume affirms the everlasting impact of Gribov's scientific heritage upon the physics of the 21st century.

This book was released on 2016-10-27 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Theory of Particle Physics describes successfully the observed strong and electroweak interactions, but it is not a final theory of physics, since many aspects are not understood: (1) How can gravity be introduced in the Standard Theory? (2) How can we understand the observed masses of the leptons and quarks as well as the flavor mixing angles? (3) Why are the masses of the neutrinos much smaller than the masses of the charged leptons? (4) Is the new boson, discovered at CERN, the Higgs boson of the Standard Theory or an excited weak boson? (5) Are there new symmetries at very high energy, e.g. a broken supersymmetry? (6) Are the leptons and quarks point-like or composite particles? (7) Are the leptons and quarks at very small distances one-dimensional objects, e.g. superstrings? This proceedings volume comprises papers written by the invited speakers discussing the many important issues of the new physics to be discovered at the Large Hadron Collider.

Download or read book Jet Physics at the LHC written by Klaus Rabbertz and published by Springer. This book was released on 2016-10-11 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the latest experimental results on jet physics from proton-proton collisons at the LHC. Jets allow to determine the strong coupling constant over a wide range of energies up the highest ones possible so far, and to constrain the gluon parton distribution of the proton, both of which are important uncertainties on theory predictions in general and for the Higgs boson in particular.A novel approach in this book is to categorize the examined quantities according to the types of absolute, ratio, or shape measurements and to explain in detail the advantages and differences. Including numerous illustrations and tables the physics message and impact of each observable is clearly elaborated.

Download or read book Conformal Maps of a Riemannian Surface into the Space of Quaternions written by Dr. Jörg Richter and published by . This book was released on 1997-09-01 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present work, a coordinate-free way is suggested to handle conformal maps of a Riemannian surface into a space of constant curvature of maximum dimension 4, modeled on the non-commutative field of quaternions. This setup for the target space and the idea to treat differential 2-forms on Riemannian surfaces as quadratic functions on the tangent space, are the starting points for the development of the theory of conformal maps and in particular of conformal immersions. As a first result, very nice conditions for the conformality of immersions into 3- and 4-dimensional space-forms are deduced and a simple way to write the second fundamental form is found. If the target space is euclidean 3-space, an alternative approach is proposed by fixing a spin structure on the Riemannian surface. The problem of finding a local immersion is then reduced to that of solving a linear Dirac equation with a potential whose square is the Willmore integrand. This allows to make statements about the structure of the moduli space of conformal immersions and to derive a very nice criterion for a conformal immersion to be constrained Willmore. As an application the Dirac equation with constant potential over spheres and tori is solved. This yields explicit immersion formulae out of which there were produced pictures, the Dirac-spheres and -tori. These immersions have the property that their Willmore integrand generates a metric of vanishing and constant curvature, respectively. As a next step an affine immersion theory is developped. This means, one starts with a given conformal immersion into euclidean 3-space and looks for new ones in the same conformal class. This is called a spin-transformation and it leads one to solve an affine Dirac equation. Also, it is shown how the coordinate-dependent generalized Weierstrass representation fits into the present framework. In particular, it is now natural to consider the class of conformal immersions that admit new conformal immersions having the same potential. It turns out, that all geometrically interesting immersions admit such an isopotential spin-transformation and that this property of an immersion is even a conformal invariant of the ambient space. It is shown that conformal isothermal immersions generate both via their dual and via Darboux transformations non-trivial families of new isopotential conformal immersions. Similarly to this, conformal (constrained) Willmore immersions produce non-trivial families of isopotential immersions of which subfamilies are (constrained) Willmore again having even the same Willmore integral. Another observation is, that the Euler-Lagrange equation for the Willmore problem is the integrability condition for a quaternionic 1-form, which generates a conformal minimal immersions into hyperbolic 4-space. Vice versa, any such immersion determines a conformal Willmore immersion. As a consequence, there is a one-to-one correspondence between conformal minimal immersions into Lorentzian space and those into hyperbolic space, which generalizes to any dimension. There is also induced an action on conformal minimal immersions into hyperbolic 4-space. Another fact is, that conformal constant mean curvature (cmc) immersions into some 3-dimensional space form unveil to be isothermal and constrained Willmore. The reverse statement is true at least for tori. Finally a very simple proof of a theorem by R.Bryant concerning Willmore spheres is given. In the last part, time-dependent conformal immersions are considered. Their deformation formulae are computed and it is investigated under what conditions the flow commutes with Moebius transformations. The modified Novikov-Veselov flow is written down in a conformal invariant way and explicit deformation formulae for the immersion function itself and all of its invariants are given. This flow commutes with Moebius transformations. Its definition is coupled with a delta-bar problem, for which a solution is presented under special conditions. These are fulfilled at least by cmc immersions and by surfaces of revolution and the general flow formulae reduce to very nice formulae in these cases.
