“…Fortunately, despite the large uncertainties, these rates can be very decisive in discriminating among the different quark model predictions. Recently the CLAS collaboration at Jefferson Lab published a new measurement of the radiative decay widths of the excited hyperons Σ 0 (1385) and Λ(1520) [2]. The measured decay rate for Λ(1520) → γ Λ(1116), Γ γ = 167 ± 43 +26 −12 keV [2], confirms the recent result of Antipov et al [3] and the rate measured a long time ago by Mast et al [4].…”

Electromagnetic decay ofΛ(1520)

The electromagnetic decay processes of excited hyperon states are a very sensitive probe of the structure of hyperons. We will argue that the recent measurements of electromagnetic decay rates indicate that the wave functions of the hyperon ground states should contain sizeable components of excited quark states (configuration mixing). Flavor-SU (3) is a broken symmetry and it appears that the hyperon wave functions should preferably be written in a uds-basis, where only the light u and d quarks are symmetrized, and not in the usual SU (6)-basis.

“…However, the radiative decays of the excited hyperon states have very small branching ratios and to date very few electromagnetic transition rates have been measured. Recently, the CLAS collaboration at Jefferson Lab has reported a new measurement of the radiative decay widths of the Σ 0 (1385) and the Λ(1520) [20], which, as argued in Ref. [21], suggests that the wave functions of the hyperon ground states should contain sizable components of excited quark states (configuration mixing).…”

The radiative decay of the Λ(1405) and its two-pole structure

2007

We evaluate theoretically the radiative decay widths into γΛ and γΣ 0 of the two poles of the Λ(1405) found in chiral unitary theories and we find quite different results for each of the two poles. We show that, depending on which reaction is used to measure the Λ(1405) radiative decays, one gives more weight to one or the other pole, resulting in quite different shapes in the γΛ(Σ 0 ) invariant mass distributions. Our results for the high-energy pole agree with those of the empirical determination of the γΛ and γΣ 0 radiative widths (based on an isobar model fitting of the K − p atom data), which are sometimes referred to as "experimental data". We have made a detailed study of the K − p → π 0 γΛ(Σ 0 ) and π − p → K 0 γΛ(Σ 0 ) reactions and have shown that they, indeed, lead to different shapes for the γΛ(Σ 0 ) invariant mass distributions.

“…Nonetheless, recent advances on the radiative decays of these resonances, both experimental and theoretical (see, e.g., Refs. [38,39]) are very promising and may help to develop a more complete model in the future.…”

ν¯inducedK¯production off the nucleon

et al. 2012

The charged current antikaon production off nucleons induced by antineutrinos is studied at low and intermediate energies. We extend here our previous calculation on kaon production induced by neutrinos. We have developed a microscopic model that starts from the SU (3) chiral Lagrangians and includes background terms and the resonant mechanisms associated to the lowest lying resonance in the channel, namely, the Σ * (1385). Our results could be of interest for the background estimation of various neutrino oscillation experiments like MiniBooNE and SuperK. They can also be helpful for the plannedν−experiments like MINERνA, NOνA and T2K phase II and for beta-beam experiments with antineutrino energies around 1 GeV.
