“…Therefore, the η − η mixing, which is neglected in many of the former analyses, increase the η-nucleon scattering length relative to the pure octet η by a factor of about 2 [59]. For the sake of completness, it is important to stress that based on the close to threshold cross sections measured for the pp → ppK + K − reaction [60-68] the scattering length and effective range of the interaction between strange pseudoscalar mesons K + K − were recently estimated [65,69]. The resultant values are consistent with zero with rather large uncertaintes.…”

During the last decade large samples of data have been collected on the production of the groundstate pseudoscalar mesons in collisions of proton or deuteron beam with hydrogen or deuterium target. These measurements have been performed in the vicinity of the kinematical threshold for meson production where only a few partial waves in both initial and final state are expected to contribute to the production process. This simplifies significantly the interpretation of the data, yet still appears to be challenging due to the three or four particle final state systems with a complex hadronic potential. We review experiments and phenomenology of the near threshold production of the ground-state mesons in the few-body final states as for example: nucleus-meson and nucleon-nucleon-meson, and report on the status of the search of the mesic-nuclei (a meson-nucleus bound states). Experimental advantages of measurements close to the kinematical threshold are discussed, and general features of the production mechanism of the η and η mesons in the nucleon-nucleon collisions are presented emphasising results of measurements of spin and isospin dependence of the production cross sections.

“…Techniques such as scattering experiments and X-ray spectroscopy of kaonic atoms [1] as well as production experiments close to threshold [2][3][4][5][6][7] have been used over many years. Theoretical investigations based on the experimental results have also been performed [8][9][10][11][12][13][14][15][16][17][18][19].…”

101) 102 J. Zmeskal et al.The antikaon-nucleon (KN ) interaction close to threshold provides crucial information on the interplay between spontaneous and explicit chiral symmetry breaking in low-energy QCD. In this context, the importance of kaonic deuterium X-ray spectroscopy has been well recognized, but no experimental results have yet been obtained due to the difficulty of the measurement. We propose to measure the shift and width of the kaonic deuterium 1s state with an accuracy of 60 eV and 140 eV, respectively, at J-PARC. These results, together with the kaonic hydrogen data (KpX at KEK, DEAR and SIDDHARTA at DAΦNE), will then permit the determination of values of both the isospin I = 0 and I = 1 antikaon-nucleon scattering lengths and will provide the most stringent constraints on the antikaon-nucleon interaction, promising a breakthrough. Refined Monte Carlo studies were performed, including the investigation of background suppression factors for the described setup. These studies have demonstrated the feasibility of determining the shift and width of the kaonic deuterium atom 1s state with the desired accuracy of 60 eV and 140 eV.

“…The kaon-antikaon interaction was studied in several proceses, e.g. in the pp → ppK + K − reaction near the kinematical threshold but the strong interactions of protons in the final state made the interpretation of the results very difficult [1][2][3]. There are no such obstacles in the KKγ system.…”

We present studies of the e + e − → K + K − γ reaction for the e + e − center-ofmass energies close to the φ(1020) meson mass. Different mechanisms leading to the final state are considered. The strong interaction amplitudes of the K + K − pairs in the Swave are taken into account. In addition, the photon emission in the initial state, the final state radiation effects and all the possible interference terms are included in the transition matrix elements. The K + K − effective mass distributions and the angular dependence of the reaction cross-section are calculated.
