Sterile Neutrino Anarchy [PDF]
Physical Review D, 2013 Lepton mixing, which requires physics beyond the Standard Model, is surprisingly compatible with a minimal, symmetryless and unbiased approach, called anarchy. This contrasts with highly involved flavor symmetry models. On the other hand, hints for light

Sterile Plus Active Neutrinos and Neutrino Oscillations [PDF]
International Journal of Theoretical Physics, 2013 Using a 3 + 1 neutrino model with one sterile and the three standard active neutrinos with a 4x4 unitary transformation matrix, U, relating flavor to mass neutrino states, the probability of $\nu_\mu$ to $\nu_e$ transition is estimated using sterile ...

Light Unstable Sterile Neutrino [PDF]
Physical Review D, 2001 The three massless active (doublet) neutrinos may mix with two heavy and one \underline {light} sterile (singlet) neutrinos so that the induced masses and mixings among the former are able to explain the present data on atmospheric and solar neutrino ...

Investigating Sterile Neutrino Flux in the Solar Neutrino Data
Advances in High Energy Physics, 2019 There are compelling evidences for the existence of a fourth degree of freedom of neutrinos, i.e., sterile neutrino. In the recent studies the role of sterile component of neutrinos has been found to be crucial, not only in particle physics, but also in ...

, 1999 The notion of sterile neutrinos is discussed. The schemes of mixing of four massive neutrinos, which imply the existence of sterile neutrinos, are briefly considered. Several model independent methods that allow to reveal possible transitions of solar neutrinos into sterile states are presented.

Sterile neutrinos in astrophysical neutrino flavor [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Current global constraints in neutrino mixing parameters translate to lax PMNS unitarity relations. In this work, we explore the lack of non-unitarity in the neutrino mixing matrix via the astrophysical neutrino flavor content in both standard paradigms, as well as those involving sterile neutrinos.

Sterile neutrino Dark Matter [PDF]
Progress in Particle and Nuclear Physics, 2019 We review sterile neutrinos as possible Dark Matter candidates. After a short summary on the role of neutrinos in cosmology and particle physics, we give a comprehensive overview of the current status of the research on sterile neutrino Dark Matter. First we discuss the motivation and limits obtained through astrophysical observations.
