Using the pinch technique we construct at one-loop order a neutrino charge radius, which is finite, depends neither on gauge-fixing parameter nor scheme employed, and process independent. This definition stems solely from an effective proper photon-neutrino vertex, with no reference to box or self-energy contributions. The role of $\mathrm{WW}$ in this construction critically examined. In particular it shown that exclusion radius not matter convention but fact dynamically realized when...
We have examined the bounds on nonstandard WWV couplings that can be extracted from existing low-energy data, without assuming some are zero; we use a regularization procedure for loops gives gauge-invariant limit and results do not depend how integrations performed. These turn out to only little bit better than those given by unitarity requirements; in addition, relations between parameters extracted. The should interpreted mean WWZ WW\ensuremath{\gamma} vertices very well constrained at...
It is shown that the probe-independent charge radius of neutrino a physical observable; as such, it may be extracted from experiment, at least in principle. This accomplished by expressing set experimental ${\ensuremath{\nu}}_{\ensuremath{\mu}}\mathrm{\text{\ensuremath{-}}}e$ cross sections terms finite and two additional gauge- renormalization-group-invariant quantities, corresponding to electroweak effective mixing angle.
The τ lepton magnetic moment theoretical predictions and measurements are reviewed. While it is believed that such a high mass particle good candidate to show up new physics, this not the case now. of elementary fermions, in particular anomalous electron, had an historical impact both relativistic quantum mechanics field theories. Besides, many physics models were discarded when confronted with these magnitudes. More recently, discrepancy experiments for muon still open issue. For lepton,...
We compute the top quark right coupling in aligned two-Higgs-doublet model. In Standard Model real part of this is dominated by QCD-gluon-exchange diagram, but imaginary part, instead, purely electroweak at one loop. Within model we show that values for up to order magnitude larger than prediction can be obtained. For contribution find it 2 × 10−4. also present detailed results loop analytical computation.
The most general parametrization of the $tbW$ vertex includes a right coupling $V_R$ that is zero at tree level in standard model. This quantity may be measured Large Hadron Collider where physics top decay currently investigated. present new models and/or through radiative corrections, so its measurement can sensitive to non physics. In this paper we compute leading electroweak and QCD contributions value starting point order separate model effects and, then, search for We also propose...
A description of the adiabatic approximation in terms time-evolution operator is presented. Corrections to are studied, and it seen that these can be obtained a simple way case rapidly oscillating Hamiltonian.
