Ive heard that soon after the big bang matter and antimatter was created in equal proportions and that majority of the matter-antimatter annihilated among each other, somehow only a small fraction of matter remained......... my question is.... what was the form of the matter or antimatter which was annihilated? was it mostly in baryons or mesons? i.e. mostly baryons annihilating among each other or mesons annihilating among each other? what was the ratio?
