Strong Coupling Constants of the Octet Baryons to K and Mesons in Light Cone QCD Sum Rules

摘要

In this work, the strong coupling constants of the octet baryons to the K and mesons are studied within the Light Cone QCD sum rule method. It is well known that in the SU(3)f limit, these couplings can be expressed in terms of only 2 constants, so called F and D constants. In this work, the SU(3)f symmetry violating effects are also studied and it is shown that all the coupling constants can be expressed in terms of four analytical functions of the quark parameters.
