Solving Weak Interactions: W- vs W+

AI Thread Summary
Weak interactions involve the exchange of W- or W+ bosons, with beta minus decay associated with W- and beta plus decay with W+. Understanding which boson to use in unknown reactions can be challenging, but charge conservation plays a crucial role in determining the appropriate interaction. W bosons are primarily involved in quark flavor changes, and for A-level students, focusing on memorizing specific reactions is advisable due to the complexity of W boson behavior. The emission or absorption of W bosons adds to the confusion, but grasping the basics of charge conservation can aid in identifying the correct interactions. Mastering these concepts will enhance comprehension of weak interactions in particle physics.

Well its not really a homework question but I have looked through the tutorials and am still at a loss.

Homework Statement


During weak interactions the particle exchanged is either W- W+ or Z0. The thing is, I get confused which weak interactions involve W- and which involve W+. I know beta minus decay is W- and beta plus W+ but how do I work it out for an unknown reaction?


Homework Equations


Is charge conservation involved, if so how?

Any guidance would be much appreciated.

W bosons are primarily seen in quarks flavour changes. I take it you are doing A-levels, or equivalent. If you are don't worry about the rules and just learn the few reactions you're given. I say this because W bosons can either be emited or absorbed which makes it a bit more difficult.

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...
