weak "force" this is really just a question about terminology, so Im not expecting any overly complex answers. Im familiar with the weak interaction, but in what sense is this a force? It is unlike anything that we would consider a force.. The only sense in which I can see it being called a force is that it is identical to the electromagnetic force (which is clearly a force) at high energies. However, since this is the case, what exactly does an electro-weak interaction look like? Does it resemble a classical force? The definition of "classical force" Im using here is basically just a force whose feynman diagram involves particles either repelling or attracting each other and being unchanged at the end. Another possible definition would be that U = gradiant(F dot r) (I might have the equation slightly wrong, Im kind of tired and dont remember the exact format equation but the point is the same). Even with this definition I dont see how the weak interaction can be called a force. Can anyone clear this up for me?
