Article Citation - WoS: 8Interpretation of the Λc< Baryon Newly Seen by Belle Collaboration and Its Possible Bottom Partner(Springer, 2022) Azizi, K.; Sarac, Y.; Sundu, H.The developments in the experimental facilities and analyses techniques have recently lead to the observation of many hadronic states ranging from excitations of conventional hadrons to various exotic states. The baryons with single heavy quark are among these states providing an attractive field of research to get a better understanding of the nonperturbative nature of the strong interaction. Recently, the Belle Collaboration announced observation of the state Lambda(c)(2910)(+) with a mass 2913.8 +/- 5.6 +/- 3.8 MeV/c(2) and width 51.8 +/- 20.0 +/- 18.8 MeV. In the present study, by the mass analyses of different excitations at A c channel and their comparison with existing experimental information, we find that the spin-parity of this newly found excited state is J(P) = 1/2(-) and it is a 2 P state denoting by Lambda(c)(1/2(-), 2 P). We predict its current coupling as well, which can be served as one of the main input parameters to investigate different decays and interactions of this particle. We also determine the mass and current coupling of Lambda(b)(1/2(-), 2 P) as possible bottom counterpart of the new Lambda(c)(2910)(+) state, which may be in agenda of different experiments in near future.Article Citation - WoS: 15Citation - Scopus: 15Strong Σbn B and Σcn D Coupling Constants in Qcd(Elsevier, 2015) Azizi, K.; Sarac, Y.; Sundu, H.We study the strong interactions among the heavy bottom spin-1/2 Sigma(b) baryon, nucleon and B meson as well as the heavy charmed spin-1/2 Sigma(c) baryon, nucleon and D meson in the context of QCD sum rules. We calculate the corresponding strong coupling form factors defining these vertices by using a three point correlation function. We obtain the numerical values of the corresponding strong coupling constants via the most prominent structure entering the calculations. (C) 2015 Elsevier B.V.

The work covers the semileptonic transitions of the Xi(b) and Xi(c) baryons. The form factors for the transitions Xi(b) -> Xi l(+)l(-) and Xi(c) -> Xi lv are obtained using their currents in the most general form. The obtained form factors are also used to calculate the decay widths and branching ratios of the considered transitions.Article Citation - WoS: 12Citation - Scopus: 12Fcnc Transitions of Λb,c< To Nucleon in Sm(Iop Publishing Ltd, 2010) Azizi, K.; Bayar, M.; Sarac, Y.; Sundu, H.We provide a comprehensive study of semileptonic flavor-changing neutral current transitions for Lambda(b) -> nl(+) l(-) and Lambda(c) -> pl(+) l(-) in the context of light cone QCD sum rules. Using the most general form of the interpolating current for Lambda(b),(c), as well as nucleon distribution amplitudes, we calculate all 12 form factors entering the calculations in full theory. We obtain the order of heavy quark effective theory violation and argue that the Lambda(b) -> nl(+) l(-) case can be studied at LHC, but the other one has a very small branching ratio.Article Citation - WoS: 13Citation - Scopus: 14On the Strong Coupling N(*)n(*)π(Springer, 2016) Azizi, K.; Sarac, Y.; Sundu, H.We study the strong vertices N*N pi, N*N*pi and NN pi in QCD, where N* denotes the negative-parity N(1535) state. We use the most general form of the interpolating currents to calculate the corresponding strong coupling constants. It is obtained that the coupling associated to N*N pi vertex is strongly suppressed compared to those related to two other vertices. The strong coupling corresponding to N*N*pi is obtained to be roughly half of that of NN pi vertex. We compare the obtained results on N*N pi and NN pi vertices with the existing predictions of other theoretical studies as well as those extracted from the experimental data.
