Are there any experimental bounds on the ratio of neutrinos to antineutrinos in the universe?

Let's start simple, It's impossible to quantize a exact proportion as you are aware. The electron antineutrino is rather an interesting phenomenon, so let me explain that. In pair production one ...

Is it theoretically possible to aim a neutrino's trajectory without using a massive celestal body to aim it?

Neutrinos interact so seldom that it is not possible to align them after they are created. The DUNE experiment at FermiLab does create a beam of neutrinos. They actually create a beam of protons. Then ...

Where is antineutrino in standard model Lagrangian?

Assuming Neutrinos are indeed Majona Particles makes it so that saying that there aren't antineutrinos feel somewhat incorrect, as it isn't that there aren't antineutrinos, Majorana particles are ...

How does Diagonalizing Mass Terms Affect the Lagrangian?

This is a response to the first part of your question, not related to the neutrino physics specifically. Suppose we start with a generic Lagrangian with $N$ scalar fields where both the kinetic and ...

Questioning the Probability Expression for Neutrino Oscillation in Griffiths' "Introduction to Elementary Particles"

I think I've identified the issue, and it seems to be related to the notation used by the author. When we define the state $$|ψ(t)>=cosθe^{-(i/ℏ)E₁t}|ν₁>+sinθe^{-(i/ℏ)E₂t}|ν₂>$$ in terms of ...

Questioning the Probability Expression for Neutrino Oscillation in Griffiths' "Introduction to Elementary Particles"

Apologies, in my earlier answer I had not seen the book (could access the earlier version, which has your typo). The transition/overlap amplitude at time t between these two states is, as you set it ...
