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 update our Standard Model predictions for g-2 of the muon and hadronic contributions to running QED coupling, Delta alpha_had^(5)(M_Z^2). Particular emphasis is put on recent changes in from new data 2pi channel energy region just below 2 GeV. In particular, e+e- -> pi+pi- contribution we include `radiative return' KLOE BaBar. also BaBar other exclusive channels. make a detailed study effect replacing measurements inclusive cross section, sigma(e+e- hadrons), by sum channels interval 1.43...
This work presents a complete reevaluation of the hadronic vacuum polarization contributions to anomalous magnetic moment muon, aμhad,VP, and effective QED coupling at mass Z boson, Δαhad(MZ2), from combination e+e−→hadrons cross section data. Focus has been placed on development new data method, which fully incorporates all correlated statistical systematic uncertainties in bias free approach. All available have analyzed included, where compilation yielded full R-ratio its covariance matrix...
Following updates in the compilation of $e^+e^-\rightarrow{\rm hadrons}$ data, this work presents re-evaluations hadronic vacuum polarisation contributions to anomalous magnetic moment electron ($a_e$), muon ($a_\mu$) and tau lepton ($a_\tau$), ground-state hyperfine splitting muonium also running QED coupling at mass scale $Z$ boson, $\alpha(M_Z^2)$. Combining results for with recent light-by-light corrections, electromagnetic weak contributions, deviation between measured value $a_\mu$ its...
This paper introduces a new approach to measure the muon magnetic moment anomaly |$a_{\mu} = (g-2)/2$| and electric dipole (EDM) |$d_{\mu}$| at J-PARC facility. The goal of our experiment is |$a_{\mu}$| using an independent method with factor 10 lower momentum, 20 smaller diameter storage-ring solenoid compared previous ongoing |$g-2$| experiments unprecedented quality storage field. Additional significant differences from present experimental include 1000 transverse emittance beam...
Taking the solar and atmospheric neutrino experiments into account we discuss lepton flavor violating processes, such as $\tau\to\mu\gamma$ or $\mu\to e\gamma$, in minimal supersymmetric standard model with right-handed neutrinos (MSSMRN) SU(5) GUT (SU(5)RN). The predicted branching ratio of e\gamma$ MSSMRN MSW large angle solution is so that it goes beyond current experimental bound if second-generation Majorana mass $M_{\nu_2}$ greater than $\sim 10^{13}(\sim 10^{14})$GeV for...
We calculate $g\ensuremath{-}2$ of the muon and QED coupling $\ensuremath{\alpha}{(M}_{Z}^{2}),$ by improving determination hadronic vacuum polarization contributions their uncertainties. include recently reanalyzed CMD-2 data on ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}.$ carefully combine a wide variety for ${e}^{+}{e}^{\ensuremath{-}}$ production hadrons obtain optimum form...

We study the littlest Higgs model with $T$ parity at CERN LHC through pair productions of $T$-odd top quark partner (${T}_{\ensuremath{-}}$) which decays into and lightest particle. identify region parameters favored by electroweak cosmological considerations. The signal background events are simulated fast detector simulation to discovery potential LHC. find that hemisphere analysis recently proposed CMS Collaboration is very useful separate from $t\overline{t}$ background. discuss...
We update our Standard Model predictions for g-2 of the muon and hadronic contributions to running QED coupling, Δα(5)had(M2Z). Particular emphasis is put on recent changes in from new data 2π channel energy region just below 2 GeV.
We show that, in the minimal supersymmetric standard model, possibility for lightest $CP$-even Higgs boson to be lighter than $Z$ (as low as about 60 GeV) is, contrary usual belief, not yet excluded by CERN LEP2 search nor any direct searches particles at high energy colliders. The characteristic of light scenario (LHS) is that $ZZh$ coupling and decay branching ratio $\mathrm{Br}(h/A\ensuremath{\rightarrow}b\overline{b})$ are simultaneously suppressed a result generic loop corrections....
We use a new compilation of the hadronic $R$-ratio from available data for process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\text{hadrons}$ to determine strong coupling, ${\ensuremath{\alpha}}_{s}$. make all threshold center-of-mass energy 2 GeV by employing finite-energy sum rules. Data above GeV, which at present far fewer high-precision experimental are available, do not provide much additional constraint but fully consistent with values ${\ensuremath{\alpha}}_{s}$ we obtain....
Branching ratio of $\mu \to \e \gamma$ is evaluated in the supersymmetric SU(5) grand unified theory taking account higher dimensional operators, which reproduce realistic quark and lepton masses mixing parameters. It shown by numerical calculation that at large $\tan\beta$ branching enhanced a few orders magnitude since flavor mixings for both left- right-handed sleptons are induced effect operators.
In our previous study, we used optical coherence tomography (OCT) and reported an increase in signal intensity of depth profiles between euthanasia injection cardiac arrest (CA), demonstrating the potential as a tool for monitoring/diagnosing brain tissue viability [Appl. Opt.48, 4354 (2009)]. Here, first time to knowledge, measured three-dimensional (3D) OCT images through thinned skull changing temperatures rat brain. The measurements were made at 10 min intervals 210 evaluate correlations...
It has been argued in the literature that search for slepton oscillation phenomenon can be a powerful probe of intergenerational mixing between sleptons, once sleptons are found at future colliders. In this paper we estimate possible reach lepton colliders probing left-handed flavor mixing, especially first and third generations, on which constraints imposed by other processes such as $\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\tau}}e\ensuremath{\gamma}$ very weak.
