Masses of the Light Quarks
The magnitude of m u , m d and m s is discussed on the basis of Chiral Perturbation Theory. In particular, the claim that m u = 0 leads to a coherent picture for the low energy structure of QCD is examined in detail. It is pointed out that this picture leads to violent flavour asymmetries in the matrix elements of the scalar and pseudoscalar operators, which are in conflict with the hypothesis ...
متن کاملDynamical masses of quarks in quantum chromodynamics
Using Dyson-Schwinger equations we obtain an ultraviolet asymptotics for the dynamical mass of quark in QCD mD(p) = 〈q̄q〉 3 ḡ2(p2/μ2, g2 R) p2 ( ḡ2(p2/μ2, g2 R) g2 R )−d . We also determine a numerical value for the π meson decay constant fπ. Electronic version of the paper published in Russ. Phys. J. 25, 55 (1982). As is well known, strong interactions at high energies are approximately invaria...
متن کاملThe masses of the light quarks
The talk reviews the current status of knowledge concerning mu, md and ms. Qualitative aspects of the resulting picture for the breaking of isospin and eightfold way symmetries are discussed. At a more quantitative level, the review focuses on the chiral perturbation theory results for the masses of the Goldstone bosons. The corresponding bounds and estimates for the ratios mu/md and ms/md are ...
متن کاملNeutrino Masses and Mixing: Leptons versus Quarks
Comparison of properties of quark and leptons as well as understanding their similarities and differences is one of the milestones on the way to underlying physics. Several observations, if not accidental, can strongly affect the implications: (i) nearly tri-bimaximal character of lepton mixing, (ii) special neutrino symmetries, (iii) the QLC-relations. We consider possible connections between ...

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
