“…We therefore should regard the unitary chiral approach presented here as an effective chirally motivated phenomenological model that is able to describe the data on theKN interaction and related channels in a wide energy range, without compromising the good description of the low-energy data, and accommodate the new data that might become available at the experimental facilities. In this spirit, we also give predictions for other reactions that will provide additional information in this sector, such as the K 0 L p → K + 0 reaction, which is an I = 1 filtering process and has been proposed to be measured at JLAB [37], and the weak b decay into a J/ and a meson-baryon pair, a reaction that filters the I = 0 component in the final meson-baryon state [38]. In the present work, we focus on the decay of the b into η and K final meson-baryon pairs.…”

S=−1 meson-baryon interaction and the role of isospin filtering processes

2019

A study of the meson-baryon interaction in the S = −1 sector is performed, employing a chiral SU(3) Lagrangian up to next-to-leading order (NLO) and implementing unitarization in coupled channels. The model is constrained by a large set of experimental data, paying special attention to processes that are sensitive to the NLO contributions, such as the K − p → K + − , K 0 0 reactions. The consideration of additional cross sections in single isospin channels, K − p → η , η , has been found to provide NLO low-energy constants of rather similar size. The stability of these constants has also been tested by the inclusion of explicit resonant terms. Predictions for new isospin filtering processes, like the I = 1 K 0 L p → K + 0 reaction that could be measured at the proposed secondary K 0 L beam at Jlab, or the weak decay of the b into a J/ and different meson-baryon pairs in I = 0, available at LHCb, are presented. The measurement of such reactions would put valuable constraints on the chiral models describing the S = −1 meson-baryon interaction.

“…There is also a proposal to establish a secondary K 0 L beam at JLab that can then be used for producing Ωs [81]. Ω baryons can also be produced in the reaction p p →ΩΩ, a case for thePANDA project at the FAIR facility in Darmstadt [82,83].…”

Scattering of decuplet baryons in chiral effective field theory

et al. 2017

View full text Add to dashboard Cite

A formalism for treating the scattering of decuplet baryons in chiral effective field theory is developed. The minimal Lagrangian and potentials in leading-order SU(3) chiral effective field theory for the interactions of octet baryons (B) and decuplet baryons (D) for the transitions BB → BB, BB ↔ DB, DB → DB, BB ↔ DD, DB ↔ DD, and DD → DD are provided. As an application of the formalism we compare with results from lattice QCD simulations for ΩΩ and N Ω scattering. Implications of our results pertinent to the quest for dibaryons are discussed.

“…This renders their direct experimental detection very challenging, as no two-meson beam experiment could be realistically run. We rely on indirect measurements instead, of which there exist several πK scattering experiments [4,5,6,7,8] and the recent KLF proposal [9]. All the main data sets are obtained by studying meson-nucleon to meson-meson-nucleon interactions.…”

We summarize the application of dispersion relations for the determination of low energy πK interactions. In particular, we present our recent dispersive analyses for the complete study of both πK → πK and ππ → K K channels. First, we summarize our approach, we study both channels by using several families of dispersion relations and present the most relevant partial waves. Then we apply the dispersive formalism to the threshold region, where we extract many different low-energy parameters.

Physics opportunities with a secondary KL0 beam at JLab

Abstract: Following a Letter of Intent submitted to PAC43 at JLab in this talk we discuss the possibility to create a secondary K 0 L beam in Hall-D to be used with GlueX detector for spectroscopy of excited hyperons.
