The hadronic reaction pp→Σ+K0p was measured exclusively at a beam momentum of 2.95GeV/c using the TOF detector COSY storage ring. A narrow peak observed in invariant mass spectrum K0p-subsystem 1530±5MeV/c2 with significance 4–6 standard deviations, depending on background assumptions. upper limit 18±4MeV/c2 (FWHM) for its width is given by experimental resolution. corresponding total cross section estimated to be about 0.4±0.1(stat)±0.1(syst) μb. Since resonance this subsystem must have...
Superconducting flip-chip interconnects are crucial for the three-dimensional integration of superconducting circuits in sensing and quantum technology applications. We demonstrate a simplified approach device using commercially available indium microspheres an in-house-built transfer stage bonding two chips patterned with thin films. use gold-passivated niobium or nitride layer as under-bump metallization (UBM) between aluminum-based wiring interconnect. At millikelvin temperatures, our...
This paper reports results on simultaneous measurements of the reaction channels pp $ \rightarrow$ pK + \Lambda$ and \Sigma^{0}_{}$ at excess energies 204, 239, 284MeV ( 127, 162, 207MeV . Total differential cross-sections are given for both reactions. It is concluded from measured total that high-energy limit cross-section ratio almost reached an energy only about 200MeV. From distributions observed in overall CMS as well Jackson helicity frames, a significant contribution interfering...
We demonstrate the single photon counting mode at 405 and 850 nm with stoichiometric TiN-based microwave kinetic inductance detectors realized on a sapphire substrate operated bath temperatures over 300 mK. The use 15–25 nm-thick TiN layers featuring critical temperature in 2–3 K range. found that energy-resolving power R=E/ΔE exhibits an optimum temperature, occurring 300–450 mK range, which can be almost double compared to those obtained lowest temperatures. Furthermore, regime is observed...
Energy and angular dependence of double differential cross sections d$^2σ$/d$Ω$dE was measured for reactions induced by 2.5 GeV protons on Au target with isotopic identification light products (H, He, Li, Be, B) elemental heavier intermediate mass fragments (C, N, O, F, Ne, Na, Mg, Al). It found that two different reaction mechanisms give comparable contributions to the sections. The intranuclear cascade nucleon-nucleon collisions followed evaporation from an equilibrated residuum describes...
This paper reports results from a study of the reaction pp → pK0Σ+ at beam momenta p = 2950, 3059, and 3200 MeV/c (excess energies ε 126, 161, 206 MeV. Total cross-sections were determined for all energies; set differential (Dalitz plots; invariant-mass spectra two-body subsystems; angular distributions final-state particles; in helicity Jackson frames) are presented 161 The total proportional to volume available three-body phase space indicating that transition matrix element does not...
Abstract Neutron yields from proton bombardment of elemental Pb and depleted U have been measured at bombarding energies 318 800 MeV. Additionally, MeV, data were obtained for Al C. The angles/flight-paths 7.5deg/30m 30deg/40m collected in two parameter histograms tine-of-flight pulse-height order to select detector biases the analysis permit comparison calculated experimental pulse height spectra calculation efficiency. reduced absolute double-differential cross sections are good agreement...
Following optical pulses ($\lambda=405~\text{nm}$) on titanium nitride (TiN) Microwave Kinetic Inductance Detectors (MKIDs) cooled down at temperatures $T \le T_c / 20$ ($T_c \simeq 4.6~\text{K}$), we observe a large phase-response highlighting two different modes simultaneously that are nevertheless related. The first corresponds to the well-known transition of cooper-pair breaking into quasi-particles which produces known phase response. This is immediately followed by inverse response...
