Hi @Orodruin @BvU sorry for keep bugging you again, but any help would be highly appreciated

I think what I am not sure about, is how to derive the Ee given the fact that the the photon energy has to be corrected with the Doppler term and has been "boosted" by the gamma...

Hi Any hint for this ? Thanks again

Sorry, I just wanted to avoid redundancy as I already posted the link. What I have already in the reference frame of the e- for the photon E_0 = \gamma E_0^* (1- \frac{u}{c}cos\theta_0^*) \\ E_1 = \frac{E_0}{1+ \frac{E_0}{(m_e*c^2)}(1-cos\phi)} \\ E_1^*= \gamma E_1(1-...

Homework Statement In the inverse compton scattering, find the formula of the recoiled electron as a function of the incoming electron Homework Equations The energy of the incoming photon and electron are known. The Attempt at a Solution Starting from this...

Yes, that is correct ie y'=dy/ds and x'=dx/ds as you care about the change of y/x on the direction of the movement ;-) So, when you say "outside of magnets" what do you mean ? and what about x' ? is there a similar approximation (and any reference would be great!) Thanks bunch!

So, then I guess I need to calculate the actual derivative *not* just the ratio, right ?

I guess you mean relation (95) ? And what happens to the dr ? for me I am starting with some energy / px, py,pz instead...

Well, maybe I am missing something - The movement of the particles is along the z-axis (ie the reference obrit) and I need to calculate the y' = ds/dy and x'=ds/dx - So, the y' is actually the theta angle, but the phi angle accounts for the angle in the X-Y plane, while I would need the x' =...

Hello I have this problem - From a generator, I get a compton scattering with the electrons theta and phi angles. where I having the following equations for a particle px = E_particle * sin (theta) * cos (phi); py = E_particle * sin (theta) * sin (phi); pz = E_particle * cos (theta)...

Probably you missed that my library does not have it..so any other book suggestion ?

something more recent? my library does not have it...

Hi I am trying to find the equations of a charged particle inside a dipole & quadripole. Practically, I need to write a simulation program for it which assumes a beam passing through a dipole-quadripole-dipole which are setting around an arc. Is there some recommended literature ? Of course...

Hi I have been reading that we "believe" that new physics must be O(~1 TeV) and not higher and I am trying unsuccessfully to find some ref for this. What I do understand is that if we we assume the Standard Model is valid for scales Q<Λ , where Λ∼O(1TeV).At one-loop level, we get large...

Meaning of "Scale" of an events/process in MonteCarlo Hi there I do have this question - I often hear that "this depends on the scale of the process" for example when it comes to match the matrix-elements with a parton-shower program (I am new to MonteCarlo world) so, what does "scale"...
