Abstract We review the technique of calculation operator expansion coefficients. The main emphasis is put on gluon operators which appear in n ‐point functions induced by colourless quark currents. Two convenient schemes are discussed detail: abstract method and based Fock‐Schwinger gauge for vacuum field. consider a large number instructive examples important from point view physical applications.
An attempt is made to present an instanton calculus in a relatively simple form. The physical meaning of instantons explained by the example quantum-mechanical problem energy levels two-humped potential. nonstandard solution this based on analyzed, and reader acquainted with main technical elements used approach. Instantons quantum chromodynamics are then considered. Euclidean formulation theory described. Classical solutions field equations (the Belavin–Polyakov–Shvarts–Tyapkin instantons)...
We consider the contribution of charmed quarks to vacuum polarization and $\ensuremath{\gamma}\ensuremath{\gamma}$ scattering. In quantum chromodynamics calculation is reliable for small photon momenta provided that quark mass ${m}_{c}$ large compared with scale hadronic $\ensuremath{\mu}$, $4{{m}_{c}}^{2}\ensuremath{\gg}{\ensuremath{\mu}}^{2}$. By use dispersion relations, converted into a set sum rules which impose model-independent upper bounds on charmonium leptonic photonic decay rates...
We present a class of interacting nonlocal quantum field theories, in which the CPT invariance is violated while Lorentz present. This result rules out previous claim literature that violation implies invariance. Furthermore, there exists reciprocal this theorem, namely does not lead to violation, provided residual symmetry admits proper representation theory for particles. The latter occurs case theories on noncommutative space-time, place broken possesses twisted Poincar\'e With such...
We review the development and practical uses of a generalized Maupertuis least action principle in classical mechanics, which is varied under constraint fixed mean energy for trial trajectory. The original (Euler-Lagrange) constrains at every point along equivalent to Hamilton's principle. Reciprocal principles are also derived both Hamilton principles. Principle limit Schr\"{o}dinger's variational wave very useful solve problems semiclassical complete analogy with quantum Rayleigh-Ritz...
