Hi,
I was reading Sakurai's "Invariance Principles and Elementary particles". In first chapter, second paragraph (page 3), there is a line "The analogous dimensionless constant that characterizes the gravitational repulsion between two protons is ...".
Any body likes to comment on this, why there is gravitational repulsion or this is just a typo.
Thanks,
