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 reevaluate the hadronic contributions to muon magnetic anomaly, and running of electromagnetic coupling constant at Z-boson mass. include new pi+pi- cross-section data from KLOE, all available multi-hadron BABAR, a reestimation missing low-energy using results on cross sections process dynamics reevaluation experimental software package HVPTools, together with reanalysis inter-experiment inter-channel correlations, continuum perturbative QCD four loops. These improvements lead decrease in...
We reevaluate the hadronic vacuum polarisation contributions to muon magnetic anomaly and running of electromagnetic coupling constant at Z-boson mass. include newest e+e- hadrons cross-section data (among others) from BABAR VEPP-2000 experiments. For (g-2)/2 we find for lowest-order contribution (693.1 +- 3.4) 10^-10, improving precision our previous evaluation by 21%. The full Standard Model prediction differs 3.5 sigma experimental value. five-quark alpha(mZ) is evaluated be (276.0 0.9) 10^-4.
Hadronic $\ensuremath{\tau}$ decays provide a clean laboratory for the precise study of quantum chromodynamics (QCD). Observables based on spectral functions hadronic can be related to QCD quark-level calculations determine fundamental quantities like strong-coupling constant, parameters chiral Lagrangian $\ensuremath{\mid}{V}_{us}\ensuremath{\mid}$, mass strange quark, and simultaneously test concept quark-hadron duality. Using best available measurements revisited analysis theoretical...
An update of the ALEPH non-strange spectral functions from hadronic $$\tau $$ decays is presented. Compared to 2005 publication, main improvement related use a new method unfold measured mass spectra detector effects. This procedure also corrects previous problem in correlations between unfolded bins. Results QCD studies and for evaluation vacuum polarisation contribution anomalous muon magnetic moment are derived using functions. They found agreement with published results based on set
Using recently published, high-precision π + − cross section data by the BABAR experiment from analysis of e events with high-energy photon radiation in initial state, we reevaluate lowest order hadronic contribution $(a_{\mu}^{\mathrm{had},\mathrm{LO}})$ to anomalous magnetic moment muon. We employ newly developed software featuring improved interpolation and averaging, more accurate error propagation systematic validation. With new data, discrepancy between −- τ-based results for dominant...
We reevaluate the hadronic vacuum polarisation contributions to muon magnetic anomaly and running of electromagnetic coupling constant at $Z$-boson mass. include newest $e^+e^- \to$ hadrons cross-section data together with a phenomenological fit threshold region in evaluation dispersion integrals. The precision individual datasets cannot be fully exploited due discrepancies that lead additional systematic uncertainty particular between BABAR KLOE dominant $π^+π^-$ channel. For $(g-2)/2$, we...

Cytarabine is widely used in the treatment of hematological malignancies. Its common toxicities include myelosuppression and gastrointestinal disturbances. Additionally, it can cause central nervous system (CNS) symptoms, which hoarseness, ataxic tremor, gait, nystagmus, dysmetria, dysdiadochokinesia. In this article, we present first case report dysphonia, absent CNS induced by high-dose cytarabine (HiDAC) a patient with acute myeloid leukemia. The patient’s voice began to change 3 days...
We present a new lattice QCD calculation of the leading order hadronic vacuum polarization contribution to muon anomalous magnetic moment $a_\mu$. reduce uncertainties compared our earlier computation by $40\%$, arXiv:2002.12347. perform simulations on finer lattices allowing for an even more accurate continuum extrapolation. also include small, long-distance obtained using input from experiments in low-energy regime where they all agree. Combined with other standard model contributions...
With the development of consensus mechanism, researchers emphasize need to strengthen Proof Stake process. Problem like how keep transaction platform protocol fair; decentralize digital system etc. have still remained be solved. The also has potential applied in various fields.
