Hi everbody,
I am currently learning about the quark model in more detail, how the multipletts are constructed and so on. However, I wonder what particles were really found in that time? I found a list somewhere in the net stating:
1937: [tex]\mu[/tex]
1946: [tex]K^0,\bar K^0[/tex]
1947: [tex]\pi^-, \pi^+, K^+, K^-[/tex]
1949: [tex]\pi^0[/tex]
1951: [tex]\Lambda[/tex]
1952: [tex]\Xi^-[/tex]
1953: [tex]\Sigma^-[/tex], [tex]\Sigma^+[/tex]
1955: [tex]\bar p[/tex]n
1956: [tex]\Sigma^0[/tex], [tex]\nu_e[/tex]
1959: [tex]\Xi^0[/tex]
1961: [tex]\eta[/tex]
1962: [tex]\nu_\mu[/tex]
1964: [tex]\Omega^-[/tex]
But then, in this list there are e.g. no Delta-Baryons but it is always said that Gell-Mann knew about them in order to fill the dekuplett. Also, what about the rho-mesons, the omega and such? Is there any reference out there where the dates of discovery are written?
Thanks for your help!
