This is Feynman diagram of annihilation I get from wikipedia
https://en.wikipedia.org/wiki/Annihilation
I don't understand what the middle line with arrow to the right is. If I consider the left vertex and conservation of charge, it means the horizontal line with arrow to the right should carry negative charge. So it is W-?
Thanks
