Gauge invariant electromagnetic two-point function for heavy-light quark systems.
A gauge invariant electromagnetic two-point function, crucial to the investigations of the violation of isospin symmetry, is derived for heavy-light quark systems. Thus QED can be consistently introduced into the QCD Sum Rule method, which was not previously possible. The origin of mass differences in isospin multiplets has long been of great interest in nuclear and particle physics as a source...
متن کاملExact Relations for Heavy-Light Quark Systems
We derive general relations among hadronic form factors involving one heavy meson bq and another, not necessarily heavy, meson Qq. The relations are valid to all orders of mass corrections of mQ .
متن کاملIntegral equation for gauge invariant quark Green’s function
We consider gauge invariant quark two-point Green’s functions in which the gluonic phase factor follows a skew-polygonal line. Using a particular representation for the quark propagator in the presence of an external gluon field, functional relations between Green’s functions with different numbers of segments of the polygonal lines are established. An integral equation is obtained for the Gree...
متن کاملLight-Front QCD and Heavy Quark Systems
In this series of lectures, I shall begin with the current investigations on phenomenology of hadron dynamics to demonstrate the importance of solving hadronic bound states within the framework of light-front (LF) QCD. Then, I will describe the basic procedure how to formulate the canonical theory of LFQCD, including lightfront quantization of QCD, light-front gauge singularity, and light-front...
متن کاملHeavy-heavy-light quark potential in two approaches
There are a large number of studies about the interquark potential in hadrons. The interquark potential is mainly generated by gluon dynamics reflecting the SU(3) gauge symmetry. In particular, as many lattice QCD studies, the static and quenched approximation produces the only gluonic potential. However, realistic hadrons include not only gluons but also quarks, and quarks affect the interquar...
