“…In particular, our previous calculations of the quasi-bound state in theKN N system [3,4] were performed with an early phenomenological model ofKN interaction. In a series of subsequent works devoted to the K − d system [18][19][20] more accurate phenomenological models ofKN interaction were constructed and used.…”

Exact calculations of a quasibound state in theK¯K¯Nsystem

“…They were originally designed to address the influence of the number of poles of the resonance on various properties of theKN andKN N systems (quasi-bound states in K − pp and K − d, K − d scattering and 1s level shift and width of kaonic deuterium), an issue which was of relevance for the strangeness physics community, see e.g. [7][8][9].…”

Two- and three-body resonances in the $\bar{K}$NN−πΣNsystem

“…The best sets of the obtained parameters for the one-and two-pole Λ(1405) can be found in [11]. Some physical characteristics of the obtained potentials are shown in Table 1: pole positions z 1 and z 2 (obviously, z 2 exists in twopole variant of the potential only), 1s kaonic hydrogen le--vel shift ∆E 1s and width Γ 1s .…”

“…The widely used nowadays Table 2. Kaonic hydrogen 1s level shift ∆E (eV) and width Γ (eV), corresponding to the obtained scattering length: exact ( [11] and this work), derived from Deser-Trueman formula [23], and from corrected Deser-Trueman formula [22]. [23] 486 626 ∆E cDt 1s [22] −395 −411 Γ cDt 1s [22] 338 434…”

“…It is necessary to note, that energies of atomic (kaonic hydrogen 1s level) and nuclear (one-and two-pole Λ(1405)) states were obtained from the same system of equations. Details of the formalism can be found in [11].…”
