Coulomb Sum Rule for 4HE
We determine the Coulomb sum for 4He using the world data on 4He(e, e′) and compare the results to calculations based on realistic interactions and including two-body components in the nuclear charge operator. We find good agreement between theory and experiment when using free-nucleon form factors. The apparent reduction of the in-medium GEp implied by IA-interpretation of the L/T -ratios meas...
متن کاملB-Meson Properties from Modified Sum Rule Analyses
We introduce two approaches to analyses of Borel sum rules. In the first method, we analyze the sum rules in the limit M2 → ∞. Here, the sum rules become very sensitive to the chosen threshold s0. We fix the threshold by setting the daughter sum rule equal to the meson mass in this limit. The second method introduces a Borel mass dependent threshold s0(M 2). We choose functions s0(M 2) such, th...
متن کاملQcd Sum Rule Approach
In these lectures, I describe the techniques used within the QCD sum rule approach. The basic concepts of the approach are introduced using a simple model of quantum-mechanical oscillator in 2+1 dimensions. Then I discuss their field-theoretical extension and the construction of the operator product expansion for current correlators in QCD. The calculation of static parameters is illustrated on...

متن کاملQCD Sum Rule Analysis
We present a QCD sum rule calculation of the spin-symmetry violating universal function χ2(v · v′), which appears at order 1/mQ in the heavy quark expansion of meson form factors. This function vanishes in the standard approximation, where radiative effects are neglected. For the first time, the complete set of diagrams arising at order αs is evaluated. In particular, we find χ2(1) = −(3.8± 0.4...
