Stability of Neutrino Mass Degeneracy
Two neutrinos of Majorana masses m1,2 with mixing angle θ are unstable against radiative corrections in the limit m1 = m2, but are stable for m1 = −m2 (i.e. opposite CP eigenstates) with θ = 45◦ which corresponds to an additional symmetry. Pick two neutrinos, say νe and νμ. Assume their mass eigenstates to be ν1 = νe cos θ − νμ sin θ, ν2 = νe sin θ + νμ cos θ, (1) with eigenvalues m1 and m2 res...
متن کاملGeneralized mass ordering degeneracy in neutrino oscillation experiments
We consider the impact of neutral-current (NC) non-standard neutrino interactions (NSI) on the determination of the neutrino mass ordering. We show that in presence of NSI there is an exact degeneracy which makes it impossible to determine the neutrino mass ordering and the octant of the solar mixing angle θ12 at oscillation experiments. The degeneracy holds at the probability level and for arb...
متن کاملMass Degeneracy of the Higgsinos
The search for charginos and neutralinos at LEP2 can become problematic if these particles are almost mass degenerate with the lightest neutralino. Unfortunately this is the case in the region where these particles are higgsino-like. We show that, in this region, radiative corrections to the higgsino mass splittings can be as large as the tree-level values, if the mixing between the two stop st...
متن کاملStability of Predictions in Neutrino Mass Matrix with Two Zeros
We have discussed predictions of |Ue3| and JCP in the framework of the neutrino mass matrix with two zeros. The lower bound of |Ue3| is 0.05, which depends on tan θ12 and tan θ23. We have investigated the stability of these predictions taking account of small corrections to zeros, which may come from radiative corrections or off-diagonal elements of the charged lepton mass matrix. The lower bou...
متن کاملNeutrino mass constraint from CMB and its degeneracy with other cosmological parameters
We show that the cosmic microwave background (CMB) data of WMAP can give subelectronvolt limit on the neutrino mass: mν < 0.63 eV (95% CL). We also investigate its degeneracy with other cosmological parameters. In particular, we show the Hubble constant derived from the WMAP data decreases considerably when the neutrino mass is a few times 0.1 eV.
