gρσγ coupling constant in light cone QCD
The coupling constant gρσγ is determined from light cone QCD sum rules. A comparison of our result with the ones existing in literature is presented. PACS number(s): 11.55.Hx, 13.40.Hq, 14.40.Cs e-mail: [email protected] e-mail: [email protected] e-mail: [email protected]
متن کامل∆πN coupling constant in light cone QCD sum rules
We employ the light cone QCD sum rules to calculate ∆πN coupling constant by studying the two point correlation function between the vacuum and the pion state. Our result is consistent with the traditional QCD sum rules calculations and it is in agreement with the experimental value. ∗[email protected] †[email protected]
متن کاملΣQΛQπ Coupling Constant in Light Cone QCD Sum Rules
The strong coupling constants gΣQΛQπ (Q = b and c) are studied in the framework of the light cone QCD sum rules using the most general form of the baryonic currents. The predicted coupling constants are used to estimate the decay widths for the ΣQ −→ ΛQπ decays which are compared with the predictions of the other approaches and existing experimental data.

متن کاملQcd on the Light Cone*
The quantization of gauge theory at fixed light-cone time T = t Z/C provides new perspectives for solving non-perturbative problems in quantum chromodynamits. The light-cone Fock state expansion provides both a precise definition of the relativistic wavefunctions of hadrons as bound-states of quarks and gluons and a general calculus for predicting QCD processes at the amplitude level. Applicati...
متن کاملThe Light-Cone Fock Representation in QCD∗
The light-cone Fock-state representation of QCD encodes the properties of a hadrons in terms of frame-independent wavefunctions, providing a systematic framework for evaluating structure functions, exclusive hadronic matrix elements, including time-like heavy hadron decay amplitudes, form factors, and deeply virtual Compton scattering. A new type of jet production reaction, \self-resolving di r...
