Some notation<br />
With two degenerate flavours of quarks, in flavour space the linear susceptibilities<br />
form the matrix (<br />
χuu χ ud<br />
χ ud χ uu<br />
)<br />
Transforming to µ 0 = µ u + µ d and µ 3 = µ u − µ d , this matrix becomes<br />
(<br />
χuu + χ ud 0<br />
0 χ uu − χ ud<br />
)<br />
χ 3 = χ uu − χ ud = 〈 Tr M −1 M ′ M −1 M ′ − Tr M −1 M ′′〉<br />
χ ud =<br />
〈 (Tr<br />
M −1 M ′) 2 〉 and χ 0 = χ 3 + 2χ ud<br />
