I am not clear with the difference of heavy and light mesons;
1. what is their difference?
2. how can we treat their decay properties?
3.for instance many people describe them using the Bethe-Salpeter equation at 4-dimension or at 3-dimension. which one is the better method?
To help me, thank you very much!
