How does the topic of your bachelor's thesis influence your further progress in your master studies and chances to join a research group for a master's thesis? I basically try to achieve a career in experimental particle physics and I'd like to do a bachelor's thesis in said field, that is...

I just solved the puzzle by myself. The projectors and the ##\gamma##-matrices may not commute directly, but you can consider something that follows from the anti-commutation relation $$\{\gamma^5,\gamma^\mu\}=0$$. If we multiply ##\gamma^\mu## and ##P_L=\frac{1}{2}(1-\gamma^5)## we get of...

Homework Statement I'm stuck at my particle physics exercise about 4-component chiral fields. The following problem is given: "Derive the expression for the QED Lagrangian in terms of the four component right-handed and left-handed Dirac fields ##\Psi_R(x)## and ##\Psi_L(x)##, respectively."...

Hey guys! I'm a 5th year physics student from Austria and currently dealing with some tricky homework in particle physics. So I might come up with a question once in a while.
