The $\bar{K}N$ system at threshold is a sensitive testing ground for low energy QCD, especially the explicit chiral symmetry breaking. Therefore, we have measured $K$-series x rays of kaonic hydrogen atoms DA$\Phi$NE electron-positron collider Laboratori Nazionali di Frascati, and determined most precise values strong-interaction energy-level shift width $1s$ atomic state. As x-ray detectors, used large-area silicon drift detectors having excellent timing resolution, which were developed...
To study fundamental questions of hadron and nuclear physics in interactions antiprotons with nucleons nuclei, the universal PANDA detector will be built. Gluonic excitations, strange charm quarks nucleon structure studies performed unprecedented accuracy thereby allowing high-precision tests strong interaction. The proposed is a state-of-the art internal target at HESR FAIR detection identification neutral charged particles generated within relevant angular energy range. This report...
A model where a Dirac fermion is coupled to background dilaton field considered study s-wave scattering of by back ground black hole. It found that an uncomfortable situation towards information loss scenario arises when one loop correction gets involved during bosonization.
The kaonic (3)He and (4)He X-rays emitted in the [Formula: see text] transitions were measured SIDDHARTA experiment. widths of 2p states determined to be text], respectively. Both results are consistent with theoretical predictions. width is much smaller than value by experiments performed 70's 80's, while was for first time.
This document presents the technical layout and envisaged performance of Electromagnetic Calorimeter (EMC) for PANDA target spectrometer. The EMC has been designed to meet physics goals experiment, which is being developed Facility Antiproton Ion Research (FAIR) at Darmstadt, Germany. figures are based on extensive prototype tests radiation hardness studies. shows that ready construction up front-end electronics interface.
Data on the production of η mesons light nuclei near threshold are surveyed.The photoproduction 3 He and elastic scattering from this nucleus modelled in a multiple scheme positions poles both here neighbouring studied an optical potential approach.The 7 Li is compared to that within cluster model.The decay η-mesic through pion or nucleon emission also considered.
The SIDDHARTA experiment aims at a precise measurement of K -series kaonic hydrogen x-rays and the first-ever deuterium to determine strong-interaction energy-level shift width lowest lying atomic states. These measurements offer unique possibility precisely isospin-dependent -nucleon scattering lengths.
The kaonic 3He and 4He 3d→2p transitions in gaseous targets were observed by the SIDDHARTA experiment. X-ray energies of these measured with large-area silicon-drift detectors using timing information K+K− pairs produced DAΦNE e+e− collider. strong-interaction shifts widths both 2p states determined, which are much smaller than results obtained previous experiments. "kaonic helium puzzle" (a discrepancy between theory experiment) was now resolved.
The strong-interaction shift of kaonic 3He and 4He 2p states was measured using gaseous targets for the first time in SIDDHARTA experiment. determined is much smaller than values obtained experiments performed 70's 80's. Thus, problems helium (the "kaonic puzzle") definitely solved by our measurements. observation X-rays also achieved. both found to be as small a few eV.
The strong-interaction shifts and widths of kaonic hydrogen, deuterium, 3He, 4He were measured in the SIDDHARTA experiment. most precise values shift width hydrogen 1s state determined to be ϵ1s = −283 ± 36(stat)±6(syst) eV Γ1s 541±89(stat)±22(syst) eV. upper limit deuterium Kα yield was found ≤ 0.39%. In addition, 3He 2p states ϵ2p(3He) −2 2(stat) 4(syst) Γ2p(3He) 6 6(stat) 7(syst) eV; ϵ2p(4He) +5 3(stat) Γ2p(4He) 14 8(stat) 5(syst) These are important for constraints low-energy interaction...
The SIDDHARTA experiment (SIlicon Drift Detector for Hadronic Atom Research by Timing Application) had the aim to perform kaonic atoms X-ray transitions measurements, better understand aspects of low-energy QCD in strangeness sector. combined excellent kaon beam generated at DAΦNE, allowing use gaseous targets, with fast X-rays detectors: Silicon Detectors. was installed on DAΦNE autumn 2008 and took data till late 2009. Apart hydrogen deuterium we have performed helium 2p level ( L -lines)...
The SIDDHARTA (SIlicon Drift Detector for Hadronic Atom Research with Timing Application) collaboration performed X-ray spectroscopy measurement of kaonic atoms at the DAΦNE e+e−collider. Low energy negative kaons from ϕ-factory were stopped in gaseous targets to produce atoms. We employed specially designed Silicon Detectors(SDDs) detect X-rays. Based on kaonic- 4He 3d → 2p transition, we determined a new value level strong-interaction shift 4He: 0 ± 6 (stat.)± 2 (syst.) eV[1]. Together...
The SIDDHARTA experiment aims a precise measurement of K -series kaonic hydrogen x-rays and the first-ever deuterium to determine strong-interaction energy-level shifts widths lowest lying atomic states. These measurements offer unique possibility precisely isospin-dependent kaon-nucleon ( KN ) scattering lengths [1] which are directly connected with physics interaction. Kaonic Helium transitions 2p level L -lines) were as well measured. has been performed at DAΦNE e + - collider produces...
