Neutrino Mixing Sum Rules and Oscillation Experiments
The neutrino mixing sum rule θ 12 − θ 13 cos(δ) ≈ θ ν 12 provides a possibility to explore the structure of the neutrino mass matrix in the presence of charged lepton corrections, since it relates the 1-2 mixing angle from the neutrino mass matrix, θ ν 12 , to observable parameters of the PMNS mixing matrix. The neutrino mixing sum rule holds if the charged lepton mixing angles are CKM-like, i....
متن کاملSum rules of four-neutrino mixing in matter
Assuming the existence of one light sterile neutrino, we investigate the neutrino flavor mixing matrix in matter. Sum rules between the mixing parameters in vacuum and their counterparts in matter are derived. By using these new sum rules, we obtain the simple but exact expressions of the effective flavor mixing matrix in matter in terms of neutrino masses and the mixing parameters in vacuum. T...
متن کاملSum Rules of Neutrino Masses and CP Violation in the Four-Neutrino Mixing Scheme
We show that the commutator of lepton mass matrices is invariant under terrestial matter effects in the four-neutrino mixing scheme. A set of modelindependent sum rules for neutrino masses, which may be generalized to hold for an arbitrary number of neutrino families, are for the first time uncovered. Useful sum rules for the rephasing-invariant measures of leptonic CP violation have also been ...
متن کاملThe Strange-Quark Mass From QCD Sum Rules: An Update
Three different ways of determining the strange quark mass using QCD sum rules are reviewed. First, from a QCD sum rule determination of the up and down quark masses, together with the current algebra ratio ms/(mu+ md). Second and third, from QCD sum rules involving the strangeness changing vector and axial-vector current divergences, respectively. Present results are encompassed in the value: ...
متن کاملBottom-quark mass from finite energy QCD sum rules
Finite energy QCD sum rules involving both inverse and positive moment integration kernels are employed to determine the bottom quark mass. The result obtained in the MS scheme at a reference scale of 10GeV is mb(10GeV) = 3623(9)MeV. This value translates into a scale invariant mass mb(mb) = 4171(9)MeV. This result has the lowest total uncertainty of any method, and is less sensitive to a numbe...
