Deviation from bimaximality due to Planck scale effects

T Violation in Neutrino Oscillation above GUT Scale

“…Hence we can expect much larger change in θ 12 compared to θ 13 and θ 23 [9]. As one can see from the above expression of mixing angle due to Planck scale effects, depends on new contribution of mixing U = U(1 + iδθ).…”

“…We have presented a possible T/ CP violation term P T αβ and P CP αβ above GUT scale. Bimaximal scenario of neutrino mixing due to Planck scale effects [9] gives the range of mixing angle θ 12 = θ 12 ± 3.0°and modified mass square difference 21 = 21 ± (1.0 + 0.5) × 10 −5 eV 2 [12], which is correspondence to Planck scale M pl ≈ 2.0 × 10 19 GeV. The range of mixing angle θ 13 is given by [8] is θ 13 = (0.004-0.3°).…”

“…As one can see from the above expression of mixing angle due to Planck scale effects, depends on new contribution of mixing U = U(1 + iδθ). New contribution of mixing matrix also changes the symmetry properties of neutrinos [10,11].…”

Neutrino Oscillation Phase Shift from Quantum Gravity

“…Where δθ is a hermition matrix that is first order in μ [10]. The first order mass square difference M…”

ApparentCPTviolation in neutrino oscillation experiments

“…It is the purpose of this paper to offer a framework for searching for new physics in the antineutrino data. Most recent analyses [4,[6][7][8][8][9][10] of anomalies in antineutrino data have focussed on CPT violation in the neutrino mass matrix [11][12][13][14][15][16]. However there is no theoretical motivation for CPT violation, and CPT violation requires Lorentz violation which is complicated to incorporate in a complete theory that is consistent with other data.…”
