I absolutely agree with that argument. Therefore finding mass is same to
finding bump in the cross section. It has a very useful meaning
phenomenologically. However it can't give the reason how or why a particle has
a specific physical(or numerical) value. My question is if we can predict
masses of quarks or leptons purely in theoretical way, instead of experiments.

thanks for your reply.

I heard a similar idea. This idea is very interesting and curious to me.
But Frankly I do not understand enough to critisize or agree. I understand
SR, GR ,and some of cosmology. Coud you explain your idea a little bit more
in details or introduce something to read .. maybe books, articles ?

                                Thanks for all your responses.
