Query: BMN operators with a scalar fermion pair and operator mixing in N=4
  Super Yang-Mills Theory   The mixings between BMN operators with two scalar impurities and those with a
scalar fermion pair are discussed to the lowest order at planar level. For this
purpose, matrix model effective vertices are calculated to O(g^3). All the
mixing patterns are explicitly obtained.
