Abstract

X-rays produced by kaons stopping in targets of O, Mg, Al, Si, S, Co, Ni, Cu, Ag, Cd, In and Sn have been observed. The shifts, widths and yields of the last observed mesic X-ray due to the effects of the strong interaction have been measured. The results are compared with optical-model predictions.

CdZnTe detectors tested at the DAΦNE collider for future kaonic atoms measurements
2024, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
The SIDDHARTA-2 collaboration at the INFN Laboratories of Frascati (LNF) aims to perform important measurements on kaonic atoms. In parallel to the groundbreaking kaonic deuterium measurement, presently running on the DA $Φ$ NE collider at LNF, we plan to install additional detectors. The aim is to perform further kaonic atoms’ studies, taking advantage of the unique low energy and low momentum spread $K^{-}$ beam delivered by the at-rest decay of the $ϕ$ meson.
CdZnTe devices are ideal for detecting transitions toward both the upper and lower levels of intermediate-mass kaonic atoms, like kaonic carbon and aluminium. Measuring these transitions can have an important impact on the strangeness sector of nuclear physics.
We present the results obtained in two preliminary tests conducted at DA $Φ$ NE in view of measurements foreseen in 2024, with the twofold aim to tune the timing window required to reject the extremely high electromagnetic background, and to quantify the readout saturation effect due to the high rate when placed close to the Interaction Region (IR). In the first test we used a RITEC device and electronics, while for the second one commercial REDLEN detectors were coupled to a frontend electronics customized at the University of Palermo.
The results confirmed the possibility of finding and matching a proper timing window to identify the signal events and proved the better performance in terms of energy resolution of the REDLEN technology with a custom frontend electronics. In both cases, strong saturation effects were confirmed, accounting for a loss of almost 90% of the events, which will be overcome by a dedicated shielding structure foreseen for the final experimental setup.
Density-dependent K<sup>-</sup> nuclear optical potentials from kaonic atoms
1994, Nuclear Physics, Section A
The density depedence of the K⁻ optical potential V_opt(r) at zero kinetic energy is studied by fitting it to a comprehensive set of atomic data across the periodic table. Two families of solutions offering improved fits over that for a t_effϱ(r) parameterization are identified, one containing solutions for V_opt with r.m.s. radii larger than those of the matter density ϱ, as expected from finite-range folding corrections. The other gives rise to Re V_opt of a size smaller than that of ϱ. The latter family offers substantially improved fits to the data, with particularly strong attraction inside the nucleus (200 ± 20 MeV). For a subfamily of solutions, V_opt becomes repulsive at large distances, and solutions satisfying the low-density limit $V_{opt} → t_{KN} ϱ$ can be found. Comments are made on the relevance of Λ(1405) nuclear dynamics to these findings.
Microscopic kaonic-atom optical potential in finite nuclei with Λ(1405) and Σ(1385) resonances
1994, Nuclear Physics, Section A
We derive kaonic-atom optical potentials in finite nuclei microscopically by taking into account the K⁻ NΛ(1405) and K⁻ NΣ(1385) interactions. Using the microscopic optical potentials we solve kaonic atoms with the Klein-Gordon equation in momentum space and obtain the kaonic-atom level shifts and the widths. The experimental data are reproduced well. We discuss also phenomenological optical potentials and compare them with the microscopic ones. In addition, we derive optical potentials in the local-density approximation with the use of the finite-matter kaon self-energy. We find a similarity with the microscopic optical potential derived with finite geometry.
Finite-range effects in hadronic atoms. (II). Kaonic and antiprotonic atoms
1991, Nuclear Physics, Section A
Finite-range effects leading to a nonlocal optical-model description of strong-interaction level shifts and widths were studied for kaonic and antiprotonic atoms by using a coordinate-space code which had been introduced and successfully applied to fitting pionic atom data. Some difficulties, which are encountered when strong-interaction bound states appear near zero energy, are analyzed and discussed. By fitting to selected kaonic-atom and antiprotonic-atom data, the present analysis finds substantially larger ranges than for pionic atoms. These values are discussed within the context of several hadron-nucleon interaction models and nuclear multiple-scattering approaches.
Collective interaction of mesons in hot hadronic matter
1991, Nuclear Physics, Section A
We calculate momentum-dependent optical potentials (both real and imaginary parts) for mesons propagating in hot hadronic matter. For sufficiently dilute matter the results obtained are essentially model-independent, and based directly on experimental information about hadronic scattering amplitudes. Even at the lowest (break-up) temperatures available in high-energy hadronic collisions, T_f = 120–150 MeV, these potentials can significantly modify spectra of the outgoing hadron, leading to a peak at small p_t. Other observable consequences of these phenomena are changes of the line shape of ϱ-, ω- and φ-mesons, which can be observed in the dilepton mode. For such mesons, decaying inside the matter, we estimate both the expected shift and broadening of the peaks.
