Charmed baryons circa 2015

Abstract

This is essentially an update of Ref. [1] [H. Y. Cheng, Int. J. Mod. Phys. A 24 (Suppl. 1), 593 (2009)], a review of charmed baryon physics around 2007. Topics covered in this review include the spectroscopy, strong decays, lifetimes, nonleptonic and semileptonic weak decays, and electromagnetic decays of charmed baryons.

Excited state mass spectra of singly charmed baryons

“…[6,21,46,22]. The present calculated excited states are in good agreement with other theoretical predictions (See Table 12 The orbital excited state masses are mentioned in Table [14][15]. The first orbital excited state Ξ c (2790) with…”

“…We have compared these states with our calculated results in Table [4,5,[9][10][11][12][13][14][15]. From that, we have concluded their baryonic states and also assigned J P value to these unknown experimental states.…”

“…Masses are obtained in the present study for each case of the model potential, ν= 0.5 to ν=2.0. Note that, A are masses without first order correction and B are masses with first order correction in Table [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. We plot graphs for calculated excited state (S and P state) with different potential index (M → ν) (See Fig.…”

Low-lying charmed and charmed-strange baryon states

“…More experimental information as regards the charmed baryons can be found in Refs. [40][41][42][43].…”

“…In the past years important experimental progresses have been made in the field of heavy baryons [1], and we refer to reviews [2][3][4][5][6][7] for their recent progress. Especially, the LHCb experiment observed as many as five excited Ω c states at the same time [8], which is probably related to the fine structure of the strong interaction.…”
