Right-handed Electrons in Radiative Muon Decay
Electrons emitted in the radiative decay μ− → e−ν̄eνμγ have a significant probability of being right-handed, even in the limit me → 0. Such “wrong-helicity” electrons, arising from helicity-flip bremsstrahlung, contribute an amount α 4π Γ0 to the muon decay width (Γ0 ≡ G 2 Fm 5 μ/(192π )). We use the helicity-flip splitting function Dhf (z) of Falk and Sehgal (Phys. Lett. B 325, 509 (1994)) to o...
متن کاملRight - Handed Currents in B Decay Revisited
We critically re-examine the case for and against a sizeable right-handed component in the b → c charged current coupling with a strength ξ relative to the conventional left-handed current. Using data from CLEO on the decay B → Dlν, as well as our knowledge of Vcb extracted from both inclusive and exclusive processes, we are able to determine the presently allowed parameter space for ξ via HQET...
متن کاملRight - handed currents , CP violation , and B →
Precision CP violation measurements in rare hadronicB decays could provide clean signatures of parity symmetric new physics, implying the existence of SU(2)L × SU(2)R×U(1)B−L×P symmetry at high energies. New contributions to the weak scale Hamiltonian which respect parity to O(1%) in supersymmetric realizations are compatible with an SU(2)R breaking scale MR ≤ MGUT, implying that sensitivity to...
متن کاملLeptogenesis from Right-handed Neutrino Decays to Right-handed Leptons
We investigate what would be the consequences for leptogenesis of the existence of a charged SU(2)L singlet scalar δ . If such a scalar particle exists it allows the right-handed neutrinos to couple not only to left-handed lepton and Higgs doublets as in ordinary leptogenesis, but also to a right-handed charged lepton and a δ. This provides a new source of leptogenesis which can be successful i...
متن کاملThe KATRIN sensitivity to the neutrino mass and to right-handed currents in beta decay
The aim of the KArlsruhe TRItium Neutrino experiment KATRIN is the determination of the absolute neutrino mass scale down to 0.2 eV, with essentially smaller model dependence than from cosmology and neutrinoless double beta decay. For this purpose, the integral electron energy spectrum is measured close to the endpoint of molecular tritium beta decay. The endpoint, together with the neutrino ma...
