We review the present status of Standard Model calculation anomalous magnetic moment muon. This is performed in a perturbative expansion fine-structure constant $\alpha$ and broken down into pure QED, electroweak, hadronic contributions. The QED contribution by far largest has been evaluated up to including $\mathcal{O}(\alpha^5)$ with negligible numerical uncertainty. electroweak suppressed $(m_\mu/M_W)^2$ only shows at level seventh significant digit. It two loops known better than one...
We have measured the cross section of radiative process e+e- -> pi+pi-gamma with KLOE detector at Frascati phi-factory DAPHNE, from events taken a CM energy W=1 GeV. Initial state radiation allows us to obtain for pi+pi-, pion form factor |F_pi|^2 and dipion contribution muon magnetic moment anomaly, Delta a_mu^{pipi} = (478.5+-2.0_{stat}+-5.0_{syst}+-4.5_{th}) x 10^{-10} in range 0.1 < M_{pipi}^2 0.85 GeV^2, where theoretical error includes SU(3) ChPT estimate uncertainty on photon final...
A bstract The three precision measurements of the cross section σ ( e + − → π γ(γ)) using initial state radiation by KLOE collaboration provide an important input for prediction hadronic contribution to anomalous magnetic moment muon. These are correlated both statistical and systematic uncertainties and, therefore, simultaneous use these requires covariance matrices that fully describe correlations. We present construction them determine a combined measurement γ(γ)). find, from this...
The economic viability of reusing lithium-ion batteries obtained from electric vehicles is highly sensitive to increasing inner resistance and capacity fading cells. For decision making after removal the batteries, it necessary consider uncertainties in prediction remaining battery lifetime. purpose this article provide a way for lifetime by quantifying considering occurring uncertainties. According literature, major risks are non-linear change capacity, cell spreading exceeding critical...
The dipole strength of the nuclide 59Co was studied in photon-scattering experiments using bremsstrahlung produced with electron beams energies 8.6 and 12.2 MeV at facility 𝛾ELBE. We identified 130 levels up to an excitation energy 10.5 MeV. quasicontinuum unresolved transitions included analysis spectra intensities branching were estimated on basis simulations statistical 𝛾-ray cascades. photoabsorption cross section neutron-separation determined is compared predictions reaction model as...
We have studied the phi->a_0(980) gamma process with KLOE detector at Frascati phi-factory DAPhNE by detecting phi->eta pi^0 decays in final states eta->gamma and eta->pi^+ pi^- pi^0. measured branching ratios for both states: Br(phi->eta gamma)=(7.01 +/- 0.10 0.20)x10^-5 (7.12 0.13 0.22)x10^-5 respectively. also extracted a_0(980) mass its couplings to eta pi^0, K^+ K^-, phi meson from fit of invariant distributions using different phenomenological models.
The electromagnetic dipole strength below the neutron-separation energy has been studied for xenon isotopes with mass numbers A = 124, 128, 132, and 134 in nuclear resonance fluorescence experiments using ELBE bremsstrahlung facility at Helmholtz-Zentrum Dresden-Rossendorf HIgS Triangle Universities Nuclear Laboratory Durham. systematic study gained new information about influence of neutron excess as well deformation on region pygmy resonance. results are compared those obtained chain...
We present a precise measurement of the ratio R K =Γ(K→e ν(γ))/Γ(K→μ ν(γ)) and study radiative process K→e ν γ, performed with KLOE detector. The results are based on data collected at Frascati e + − collider DAΦNE for an integrated luminosity 2.2 fb−1. find =(2.493±0.025stat±0.019syst)×10−5, in agreement Standard Model expectation.
