Naive quark-pair—creation model and baryon decays

Mixing of the low-lying three- and five-quarkΩstates with negative parity

“…The most commonly accepted mechanism for quark-antiquark pair creation is the 3 P 0 model [8][9][10]. In this model the created quark-antiquark pair is in its first orbitally excited state, i.e.…”

“…For such transitions, the key ingredient is the QQ creation mechanism. Most widely accepted is the 3 P 0 model [8], which has been successfully applied to the decays of mesons and baryons [9,10], and this was also employed to analyse the sea flavor content of the ground states of the SU (3) octet baryons [11,12], as well as of the spin and electromagnetic properties of baryons [13,14]. In the 3 P 0 model, the QQ pair is created with the quantum numbers of the QCD vacuum 0 ++ , which corresponds to 3 P 0 .…”

Open Flavor Strong Decays

“…Here, we present some our results for the two-body strong decay widths of nucleon resonances in the 3 P 0 paircreation model. The decay widths are computed as [10,11,17,27,28,30,33,45] …”

“…[24]). A few years after the introduction of the 3 P 0 model [10], Le Yaouanc et al used it to compute meson and baryon open flavor strong decays [11] and also evaluated the strong decay widths of charmonium states [25]. The 3 P 0 model, extensively applied to the decays of light mesons and baryons [26], has been recently applied to heavy meson strong decays, in the charmonium [27][28][29], bottomonium [29,30] and open charm [31,32] sectors.…”

“…Several phenomenological models have been developed in order to carry out strong decay studies, including paircreation models [10][11][12][13][14][15][16][17], elementary meson emission models [18][19][20][21][22][23] and effective Lagrangian approaches (for example, see Ref. [24]).…”
