“…It is important, therefore, to consider the charmed and bottom baryons in a interrelated way between two families so that one can reliably predict the quantum numbers of the newly discovered baryons and the some existing SH baryons in the charm sector, e.g., the Σ c (2800) and Ξ ′ c (2930), which were observed about a decades ago and whose quantum numbers are not established experimentally yet [7][8][9]. For the two charmed baryons, quark models predict their quantum number to be [10][11][12][13],…”

Recently, the LHCb Collaboration observed two new bottom baryons, the Ξ b (6227) − and the Σ b (6097) ± , which arouses considerable interest in their inner structures. Stimulated by this, we re-examine the low-lying spectrum of the singly heavy baryons in the heavy quark-diquark picture. Our computation indicates that a linear Regge relation, which is derived from the rotating string model, is sufficient to describe the mass spectrum of all observed singly heavy baryons, predicting that the quantum numbers of the charmed baryons Σ c (2800) and the charm-strange baryon Ξ ′ c (2930), which remain unknown experimentally, are preferably J P = 3/2 − . Similar calculations for the bottom partners support that the newly observed baryons Σ b (6097) − and Ξ ′ b (6227) − are the 1P-wave excitations of the baryons Σ b and Ξ ′ b with J P = 3/2 − . PACS numbers: 14.40.Be, 12.40.Nn, 12.39.Ki ′ b (6227) − . Finally, the paper ends with the discussions and summary in Sec. V. II. SPIN-INDEPENDENT MASSES FOR SINGLY HEAVY BARYONSThe notion of Regge trajectory or Regge mass relation for hadrons, which connects high energy scattering and the spectrum of hadrons in general theory [14], provides us a powerful way to organize the whole spectrum of a given family of the hadrons. In the case of light hadrons, the Regge trajectories are commonly believed to be linear and parallel, and these features are also tested to be true roughly for the SH hadrons in Ref. [24] provided that the hadron mass undergoes a shift M → M − M Q , with M Q the heavy quark mass. As such, one can estimate the spin-averaged masses of Σ c and Ξ ′ c in their P-wave states with the help of the trajectory information of the partner baryons, Λ c and Ξ 0 c , which has the rich data experimentally, and so forth.

“…More accurate information about these values is definitely quite desirable. Unfortunately, in processing more recent experimental data on the D 0 → K 0 S π + π − decay, the BaBar [163] and Belle [164] collaborations (see also [165]) have not specifically separated the f 0 (980) resonance contribution from the entire array of S-wave contributions. Nevertheless, the f 0 (980) peak is clearly seen in the π + π − mass spectrum in this decay [163,164].…”

Strong isospin symmetry breaking in light scalar meson production

Siberian Branch of the Russian Academy of Sciences, prosp. Akademika Koptyuga 4, 630090 Novosibirsk, Russian FederationIsospin symmetry breaking is discussed as a tool for studying the nature and production mechanisms of light scalar mesons. We are concerned with isospin breaking effects with an amplitude ∼ √ m d − mu (instead of the usual ∼ m d − mu), where mu and m d are the u and d quark masses, whose magnitude and phase vary with energy in a resonance-like way characteristic of the KK threshold region. We consider a variety of reactions that can experimentally reveal (or have revealed) the mixing of a 0 0 (980) and f0 (980) resonances that breaks the isotopic invariance due to the mass difference between K + and K 0 mesons. Experimental results on the search for a 0 0 (980) − f0(980) mixing in f1(1285) → f0(980)π 0 → π + π − π 0 and η(1405) → f0(980)π 0 → π + π − π 0 decays suggest a broader perspective on the isotopic symmetry breaking effects due to the K + and K 0 mass difference. It has become clear that not only the a 0 0 (980) − f0(980) mixing but also any mechanism producing KK pairs with a definite isospin in an S wave gives rise to such effects, thus suggesting a new tool for studying the nature and production mechanisms of light scalars. Of particular interest is the case of a large isotopic symmetry breaking in the η(1405) → f0(980)π 0 → π + π − π 0 decay due to the occurrence of anomalous Landau thresholds (logarithmic triangle singularities), i.e., due to the η(1405) → (K * K +K * K) → (K + K − + K 0K 0 )π 0 → f0(980)π 0 → π + π − π 0 transition (where it is of fundamental importance that the K * meson has a finite width).

The role of W -exchange diagrams in baryonic B decays is poorly understood, and often taken as insignificant. We show that charmful two-body baryonic B → B cB ′ decays, where B c is an antitriplet or a sextet charmed baryon, andB ′ an octet charmless (anti-)baryon, provide a good test-bed for the study of the W -exchange topology, whose contribution is found to be non-negligible. Thehence is naturally suited for the study of the role of the W -exchange topology. We predict B(B 0 s → Λ + cp ) = (1.2 +0.7 −0.5 ) × 10 −6 , a relatively large branching ratio to be tested with a future measurement by the LHCb collaboration. Other predictions, such as B(B 0 → Ξ + cΣ − ) = (1.8 +1.0 −0.8 ) × 10 −5 , can be tested with future Belle II measurements. *
