Thank you guys for the helping any more advice would be welcomed as well.

Okay so I looked at how long I've spent and it's close to about a 1000 hours (I actually apply to positions about 5 to 7 hours a night) As I mentioned in a previous post I do a mixture and you are correct only about a 150 is the sniper approach the rest is a mixed approach.

I do a mixture basically. If the position is something I really want and am 80 to a 100 percent qualified for then I will use the sniper approach. Then for the others I have 12 resume designs (based on the type of job I'm applying to) which I chose from depending on the position that I will use...

The only question I have about the data analysis part. I apply to those type of positions because sometimes the data scientist position requires so many years experience. If you take out lower entry level jobs then there aren't a lot of options.

I need some career advice. First of off I'm a PhD graduate in physics. Yes for some stupid reason I chose particle physics. I was told by both my undergraduate and graduate program that to major in what I love since its easy for physicist to get a job doing about anything. I found out this to be...

So I am calculating the renormalization group rquations for some exotic new particles and used dimensional regularization for all the calculations up to this point. Now I am look at the vertex corrections in the massless limit in which all external momentum are equal to 0. The issue here is I...

Is there anyway you could go into a little more detail. And how did you know in the first place to pick such an SU(2)xU(1) basis. Also do you know of any good reading material besides Georgi's book which I could look at that would include this.

Yes you decompose it into block diagonal form. Or another way you can do it is do tensor products of the fundamental rep and decompose it using young tableaux methods.

I have been reading Georgi "Lie Algebras in Particle Physics" and on page 183 he mentions how that the SU(3) defining representation decomposes into an SU(2) doublet with hyperchage (1/3) and singlet with hypercharge (-2/3). I am confused on how he knows this. I apologize if this is not the...

Okay, so I am trying to understand on how to write Lagrangian in different representations. I know the formula of the SU(3) lagrangian in terms of the 3 and 3* rep. Now presume I have a model in the SU(3) 10 plet rep which includes exotic fermions not in the SM. How would I write out the...

Thanks, however this just seems as circular logic to me and confuses me cause we defined the stress energy tensor that way. I will read this book though.

Could someone point to me where they derive the follow effective Lagrangian for the Graviton coupling to matter L = \frac{1}{M_{pl{}}}h^{\mu \nu}T_{\mu \nu}

So I have a histogram with bins that contain the number of events expected at a specific energy (which I generated with a Monte Carlo).. I need to add (integrate) all the bins in a section of this histogram and find the error of this value. However, the number of events are very small approx...

Now the main issue is who do I ask to work for. I feel like since me and this advisor didn't work out that I am just not good enough and should give up.

Actually the reason is very close to the true reason. In August he told me to think a few days as he didnt think this was for me. Up to that point i do have to admit my work ethic was bad. I told him I really wanted this and just needed time to imrpove. So I actually started acting like a phd...
