On Generalized Sum Rules for Jacobi Matrices
This work is in a stream (see e.g. [4], [8], [10], [11], [7]) initiated by a paper of Killip and Simon [9], an earlier paper [5] also should be mentioned here. Using methods of Functional Analysis and the classical Szegö Theorem we prove sum rule identities in a very general form. Then, we apply the result to obtain new asymptotics for orthonormal polynomials.
متن کاملΣQΛQ transition magnetic moments in light cone QCD sum rules
Using the general form of ΣQ and ΛQ (Q = b or c) currents, ΣQΛQ transition magnetic moments are calculated in framework of the light cone QCD sum rules method. In this approach nonperturbative effects are described by the photon wave functions and only two–particle photon wave functions are taken into account. Our predictions on transition magnetic moments are μΣcΛc = −(1.5±0.4)μN and μΣbΛb = −...
متن کاملSum Rules and Moments of the Nucleon Spin Structure Functions
The nucleon has been used as a laboratory to investigate its own spin structure and Quantum Chromodynamics. New experimental data on nucleon spin structure at low to intermediate momentum transfers combined with existing high momentum transfer data offer a comprehensive picture of the transition region from the confinement regime of the theory to its asymptotic freedom regime. Insight for some ...
متن کاملOctet baryon magnetic moments in light cone QCD sum rules
Octet baryon magnetic moments are calculated in framework of the light cone QCD sum rules. The analysis is carried for the general form of the interpolating currents for octet baryons. A comparison of our results on the magnetic moments of octet baryons with the predictions of other approaches and experimental data is presented.

متن کاملMagnetic Moments of ∆ and Ω from QCD Sum Rules
QCD sum rules for the magnetic moments of ∆ and Ω− are derived using the external field method. They are analyzed by a Monte-Carlo based procedure, using realistic estimates of the QCD input parameters. The results are consistent with the measured values, despite relatively large errors that can be attributed mostly to the poorly-known vacuum susceptibility χ. It is shown that a 30% level accur...
