Hello !(adsbygoogle = window.adsbygoogle || []).push({});

My books defines the photon and Z0 boson as:

for the short read :

I have 3 questions

Are B0 and W0 orthogonal or the photon and Z0?

How do you derive that tg(t) = g'/g (with g' corresponding to B0, g to W0)

How do you derive that e = sin(t) ?

The long read:

Also W0 couples with g (same as the "normal" W+ and W-) and B0 couples with g'.

My first question is (rather dumb one but its getting late and cant think clearly anymore haha):

Are W0 and B0 orthogonal or the foton and Z0 eigenfunctions?

Second question is: My book said ==> the photon only interacts with electrical charge

I said "yes, thats very true mister book! You are finally starting to understand it !

Then he said : well, like I was saying " the photon only interacts with electrical charge, this implies that :

tg(t) = g'/g

I said " Mister book, I am sorry if I have offended you but now you are just making stuff up ! "

He answered " HAHA ! I guess YOU are the one that doesnt understand it"

Anyways we kibbeled for a long time more...

How can you derive that ?

I shut my book (up) and i tried to understand it like this :

for example define weak interaction operator A

<f|A|f> = 0 (cause doesnt interact) = cos(t) <B0|A|B0> + sin(t) <Z0|A|Z0> (With assuming B0 and Z0 were orthogonal.)

so you get 0 = g' cos(t) + g sin(t)

But then ofcourse i get a minus. I had the feeling i was doing a good job.

So i opened the book again and showed him my progress. But alas, he laughed again.

Cause under that formula there was e = sin(t) g and now I am realy confused !

I threw the sadistic book in the closest as punishment. And I fear I wont be able to open it again without understanding it first.

so please help !

Kind regards,

an idiot :)
