Is the neutrino oscillation demonstration correct ?

Posted 4 years ago

Hello,

in the demonstration on neutrino oscillation :

https://demonstrations.wolfram.com/NeutrinoOscillations/

The Delta_CP parameter could not be increased to more than 1 ? While in physics, it could belong to [0 ; 2*pi].

The current world average measurement is a central value of : 1.37 pi rad so already above the maximum value authorized by the author

Proof : http://pdglive.lbl.gov/Particle.action?node=S067&init=0

**Is there a mistake somewhere in the demonstration ? (Or maybe did I don't understand something in the demonstration ?)

Where are the exact formula used in the demonstration ? (in order to check whether they are correct of if there is a glitch, since there is always a tiny risk)

**Also, how to change the energy from 1 GeV (default) to 2 GeV ?

Thank you

Ok. Actually his email seems not to be on the web. He is probably : https://nl.linkedin.com/in/bal%C3%A1zs-mesz%C3%A9na-35487710b but one needs a account to be able to communicate with him. He did a PhD thesis, then he left physics.

Anyway, it is fine. No worries. I can't be sure if the correct formulas were implemented. But it is fine. I may rewrite the program once time available, in other language, since I don't master Mathematica language.

I'm afraid I do not know. I would hope a web search might turn it up but beyond that I have no other suggestions.

This is a domain-specific question, not, as best I can tell, anything to do with the Wolfram Language per se. Probably best to address it to the author of that Demonstration, unless someone on the forum happens to have answers.
