“…The properties of these states have been studied experimentally and theoretically (see, e.g., Refs. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] and references therein). In the present analysis, we compare our predictions of the decay widths with other available predictions by quark models [12,13] and chiral effective models [14,15].…”

“…3. Here the direct process is the new ingredient, while the sequential process has been studied in our previous work [4]. In Fig.…”

“…3. We omit the contribution of Σ * c (2520) since it is very small for the case of Λ * c (2595) decay [4]. The charmed baryon masses and decay widths are adopted from Particle Data Group (PDG) [10].…”

“…The values f a and f b are the Yukawa coupling of the first and second vertices in the sequential process through Σ c (2455) in the intermediate state, f c and f d are for those of Σ * c (2520). The detailed discussion about the amplitudes of the sequential processes can be found in our previous work [4].…”

“…Three-body decays of heavy baryons have been observed experimentally and studied theoretically by using various hadron models [1][2][3][4][5]. Their properties such as masses and decay widths have been extracted, and also spin and parity J P have been identified [6][7][8][9].…”
