Field Peskin Quantum

AI Thread Summary

The discussion centers on difficulties with calculating the derivative in equation 7.31 from Peskin and Schroeder's quantum field theory text. A user is struggling to derive the expression for Σ in dp slash and reports discrepancies with the expected result. They request assistance in correctly performing the derivative and ask for elaboration using the PF format. Participants are encouraged to share their attempts and solutions to help clarify the process. The thread highlights the collaborative nature of problem-solving in complex quantum field theory topics.

I can't do the derivative 7.31 at page 221. I try to do the derivative of Σ in dp slash, but my result is different from 7.31
Someone can help me writhing the right derivative?

Thank you in advance!

Can you elaborate here using the PF format. Also show us first what you've done so far. Thanks.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
