Tau neutrinos from muon storage rings
Charged tau leptons emerging in a long baseline experiment with a muon storage ring and a far-away detector will positively establish neutrino oscillations. We study the conversion of νμ (νμ) and of νe (νe) to ντ or ντ for neutrinos from a 20 GeV muon storage ring, within the strong mixing scheme and on the basis of the squared mass differences which are compatible with all reported neutrino an...
متن کاملCP Violation in Tau Slepton Pair Production at Muon Colliders
We discuss in detail signals for CP violation in the Higgs boson and tau–slepton sectors through the production processes μ+μ− → τ̃ i τ̃ j , where i, j = 1, 2 label the two τ slepton mass eigenstates in the minimal supersymmetric standard model. We assume that the soft breaking parameters of third generation sfermions contain CP violating phases, which induce CP violation in the Higgs sector thro...
متن کاملUpdated Implications of the Muon Anomalous Magnetic Moment for Supersymmetry
We re-examine the bounds on supersymmetric particle masses in light of the new E821 data on the muon anomalous magnetic moment and the revised theoretical calculations of its hadronic contributions. Given that the current experimental excess is only about 1.9σ, there is no strong evidence for new physics. However, if one interprets the excess as coming from supersymmetry, one can obtain bounds ...
متن کاملAn updated radiosynthesis of [18F]AV1451 for tau PET imaging
Background [18F]AV1451 is a commonly used radiotracer for imaging tau deposits in Alzheimer's disease (AD) and related non-AD tauopathies. Existing radiosyntheses of [18F]AV1451 require complex purifications to provide doses suitable for use in clinical imaging studies. To address this issue, we have modified the synthesis of [18F]AV1451 to use only 0.5 mg precursor, optimized the Boc-deprotect...
متن کاملBounds on the tau and muon neutrino vector and axial vector charge radius
A Majorana neutrino is characterized by just one flavor diagonal electromagnetic form factor: the anapole moment, that in the static limit corresponds to the axial vector charge radius 〈 r2 A 〉 . Experimental information on this quantity is scarce, especially in the case of the tau neutrino. We present a comprehensive analysis of the available data on the single photon production process e+e− →...
