The f meson has mass 1019.4 MeV/c2 and a measured energy width of 4.4 MeV/c2 . Using the uncertainty principle, estimate the lifetime of the f meson.
in 1975 it was estimated that the so-called constituent quark masses are: m_u = m_d = 336 MeV/c^2, m_s = 540 MeV/c^2, and m_c = 1500 MeV/c^2 (the bottom quark is about 4500 MeV/c^2). If this is right the average binding energy of the baryon octet is -62MeV. If they all had exactly this binding energy, what would their masses be? Compare the actual values and give the percent error. (Excluding supermultiplets)
What were the three quark types or flavors proposed?
