Energy-dependent neutrino mixing parameters at oscillation experiments
نویسندگان
چکیده
Neutrino mixing parameters are subject to quantum corrections and hence scale dependent. This means that the associated production detection of neutrinos need not coincide since these processes characterized by different energy scales. We show that, in presence relatively light new physics, dependence can lead observable consequences long-baseline neutrino oscillation experiments, such as T2K NOvA, telescopes like IceCube. discuss some experimental signatures this scenario, including zero-baseline flavor transitions, sources CP-invariance violation, apparent inconsistencies among measurements angles at experiments or channels. Finally, we present simple, ultraviolet-complete models masses which running matrix below weak scale.

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 کاملFour-neutrino mixing and long-baseline neutrino oscillation experiments
We consider the two schemes with four massive neutrinos which are compatible with the results of all neutrino oscillation experiments. We show that in these two schemes the probabilities of ν̄e disappearance and (−) νμ→ (−) νe appearance in long-baseline experiments are strongly suppressed. The investigation of neutrino properties, in particular of neutrino masses and mixing, is one of the most ...
متن کاملNeutrino masses and mixing from neutrino oscillation experiments
We discuss which information on neutrino masses and mixing can be obtained from the results of all neutrino oscillation experiments in the cases of three and four massive neutrinos. We show that in the three-neutrino case the neutrino oscillation data are not compatible with a hierarchy of couplings. In the case of four neutrinos, a hierarchy of masses is disfavored by the data and only two sch...
متن کاملNeutrino Oscillation Experiments at Fermilab
Neutrinos are special. They are the only elementary fermions which are neutral, thus they can be their own antiparticles. Their masses (if nonzero) are several orders of magnitude smaller than those of charged leptons or quarks. These two facts may be, in fact, related: with both Dirac and Majorana, masses present, the neutrino mass eigenstates will naturally split, with the light mass eigensta...
متن کاملNeutrino Oscillation Experiments at Nuclear Reactors
In this paper I give an overview of the status of neutrino oscillation experiments performed using nuclear reactors as sources of neutrinos. I review the present generation of experiments (Chooz and Palo Verde) with baselines of about 1 km as well as the next generation that will search for oscillations with a baseline of about 100 km. While the present detectors provide essential input towards...
