Hi! Yes. They prioritize 5th year master-students (which I will be in two years), which is understandable since third year students can't bring so much to the table, other then computational models, measurements and just bee there ad learn. How is it at your university?

Very interesting, I'm familiar with that. No general analogous version of that in Sweden though.

Thanks for your reply. Yes I'm a member of an association in Nano-technology at the university, which is the only association there is, and they surve the purpose to improve the faculty so it's not directly relevant.

p_1=(E_1 /c, 0, 0, sqrt(p^2c^2 - m^2 c^4)) and p_2=(E_2, 0, 0, 0) But honestly, this way of guidance makes me nothing but more confused. So no more of these hints please.

Other then the general form p=(E/c, Px, Py, Pz) I can't tell, or the quantities other then masses.

I'm not certain how to express the four-momenta in any other way, nor in lab-frame. How would you put up the equations?

Homework Statement a) [Solved] What is the threshold energy in the center of mass for production of an antiproton in a proton-proton collision? Make sure quantum numbers are conserved. (This one was easy and I manage to solve it) b) In a fixed target experiment calculate the proton beam energy...

Yes well of course? I tried solve for v in the formula for rel. Kinetic energy and plug into p=\gamma m*v but don’t get the right answer..

Homework Statement A Sigma^+ decays at rest into a neutron and a pion^+ meson, i.e. according to the reaction $$\Sigma \rightarrow n + \pi$$ The n and π masses are assumed known. The kinetic energy of the π + is measured to be 92 MeV. Determine the momentum of the pion. Homework Equations...

I’m a young very ambitious student who would like to embrace a project. As a third year undergrad I feel pretty alone. My fellow colleagues are not very forward thinking nor want to do anything besides pass the exams. Are there any platforms/associations for young theoretical physicists...

Thanks! I think I got something but its pretty general :)

Homework Statement A Higgs particle of mass M is moving in the z-direction with speed $\Beta_H$c compared to the lab system. It decays to a b-quark ans anti-b quark, each of mass m. What is the speed and direction of the b-quark compared to the lab-system, if the Higgs system, (a) it is emitted...

Thanks!

I'm using Classical mechanics by John Taylor, its ok buth rather simple.

Besides the very basics I have taking Atomphysics (semi-advanced QM), light-matter interaction, a bunch statistical mechanics and Lagrangian mechanics.
