τ weak magnetic dipole moment

Abstract

Precise measurements of magnetic and electric dipole moments are important tests of the Standard Model and beyond Standard Model physics, particularly for the electron and the muon. However, the situation presents distinctive challenges when dealing with the tau lepton due to its very short lifetime and relatively high mass. Here, we review the theoretical predictions and experimental measurements of both the anomalous magnetic and electric dipole moments of the tau lepton.

Probing the Top Quark Flavour-Changing Neutral Current at a Future Electron-Positron Collider

“…Thus, any evidence of such processes will indicate the existence of new physics. In models beyond SM such as MSSM, Technicolor, extra dimensions models higher branching ratios up to 10 −3 -10 −5 are predicted [6,7,8] which can be tested by present high energy experiments. There are several phenomenological studies in search for the anomalous tqg couplings at the Tevatron and LHC and other experiments through different channels [9,10,11,12].…”

Status of tau physics

“…In Ref. [42], data on the e + e~ -> i + i~~ cross sections measured at and above the Z° peak, the tau polarization and polarization asymmetry measured at the Z° peak, and the W -> TV branching fraction measured at LEPII and the Tevatron, are combined to yield limits on the anomalous magnetic moments of -0.007 < Refa) < 0.005 and -0.0024 < Re(a%) < 0.0025, both at the 2a level.…”

Factorization of normalization of Nash blow-up of order n of An by the minimal resolution

“…In particular, the Nash blowup try to solve singularities by iterating the process, while higher Nash looks for resolution of singularities in one step. Those questions have been treated in [12,14,7,8,11,17,19,9,10,1,4,5,18,6].…”
