Strong Coupling Constants of Heavy Baryons With Light Mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2012-06-21) The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions are described by only one invariant function, whose explicit expression is structure dependent.
Strong coupling constant of a negative parity nucleon with a pi meson in light-cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (2017-03-28) We estimate the strong coupling constant between the negative parity nucleons with pi meson within the lightcone QCD sum rules. A method for eliminating the unwanted contributions coming from the nucleon-nucleon and nucleon-negative parity nucleon transition is presented. It is observed that the value of the strong coupling constant of the negative parity nucleon N* N* pi transition is smaller by about 50% compared to the coupling constant of the positive parity NN pi transition.
Strong coupling constants of light pseudoscalar mesons with heavy baryons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-01-31) We calculate the strong coupling constants of light pseudoscalar mesons with heavy baryons within the light cone QCD sum rules method. It is shown that sextet-sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one universal invariant function for each class. A comparison of our results on the coupling constants with the predictions existing in literature is also presented.
Strong coupling constants of the octet baryons to Kand pi mesons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ (2007-06-20) In this work, the strong coupling constants of the octet baryons to the K and pi 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.
