Im quite confused with the Parity idea. I never payed much attention to it. My thought always was that Parity is related to a discrete symetry of space and it is something that can be measured and can give 1 or -1 (like the x-momentum of a particle that can give "2" "1,9" "1,8" and so on).
Nevertheless reading about the Higgs particle I saw that the Higgs Parity is "+1". My concern is that it is written as if the Parity is not something that can give "+1" or "-1" depending on randomness (the operator-eigenvalue idea) but it is just a parameter (like mass or electric charge that it is not subject to randomness).
I think that it is related to the idea that weak interactions apply to left handed particles only but I am not sure and I would like if anyone can give me an explanation of it.
I have a more or less general knowledge about SM and the math behind it. I've never actually done the math but I saw it in Peskin and such and I think I sort of followed it (I don't know, perhaps a 50%-80% of it).
Thanks for every Math or non Math explanations you can give me. Both will be very helpful.
