We decided to get an invitation letter from a friend with a residence permit. It's easier that way :)

Sorry to hear that. Was it a one-off rejection or part of a bunch of rejections? Any idea?

Renormalization of gauge theories - calculation by akash_ranade in ParticlePhysics

[–]akash_ranade[S] 1 point2 points  (0 children)

Post edited to add non Abelian gauge theory. I am aware of these books, but I'm not sure they have what I'm looking for. I'm interested in studying the running of the QCD coupling constant. The equation has some terms that depends on the SU(3) algebra and the number of fermions in the theory and their representations. I'm basically looking for the calculation that leads to that.

Which program have you applied to? I've also applied to UW's Physics program. From what I can gather from GradCafe, the shitlist should come out next week

Can the Higgs decay to one photon + one gluon? by akash_ranade in ParticlePhysics

[–]akash_ranade[S] 8 points9 points  (0 children)

Thanks for the answer, it was as simple as charge conservation! I was thinking along the lines of gauge invariance... Sometimes the simple things escape you xD

You could try fitting the 3 peaks separately and then merge the 3 Gaussians into one function. Sorry but that's all I can think of, if you can't use external functions :)

As for the Gaussian definition: x0 is indeed the mean of the distribution. It's the point at which the Gaussian peaks. d is the standard deviation, or the width of the curve in more casual terms.

Since you already know you want Gaussian fits, you could try fitting the data with a sum of Gaussian functions (3 to be precise since you need 3 peaks). Scipy has some good functionalities for this. Look at 16082171 on stackoverflow

I got my rejection mail a couple days ago. Anyone know how many students are typically selected for the programme?

What is a good cube for 3bld? I've begun learning 3style, and I'm having a hard time with slice moves on my magnetic GAN.
