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 constant of negative parity octet baryons with light pseudoscalar mesons in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2017-01-01)
The strong coupling constants of the pi and K mesons with negative parity octet baryons are estimated within the light cone QCD sum rules. It is observed that all strong coupling constants, similarly to the case for the positive parity baryons, can be described in terms of three invariant functions, where two of them correspond to the well known F and D couplings in the SU (3)(f) symmetry, and the third function describes the SU(3)(f) symmetry violating effects. We compare our predictions on the strong coup...
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.
Strong coupling constants of heavy spin-3/2 baryons with light pseudoscalar mesons
Alıyev, Tahmasıb; Savcı, Mustafa (2011-11-01)
The strong coupling constants among members of the heavy spin-3/2 baryons containing single heavy quark with light pseudoscalar mesons are calculated in the framework of the light cone QCD sum rules. Using symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions can be described in terms of one universal invariant function whose explicit expression is Lorenz structure dependent.
Strong Coupling Constants of Negative Parity Heavy Baryons with pi and K Mesons
Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2017-01-01)
The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light pi and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-sextet, sextet-antitriplet, and antitriplet-antitriplet transitions can be described by only one corresponding function. The pollution arising from the positive to positive, positive to negative, and negative to positive parity baryons transitions is eliminated by...
