05/17/2022:
  • Zhangbu: calculation of chemical potential change. If we use isobar double ratio as a change of chemical potential, I think that we can calculate simply the 
    chemical potential change: dUu and dUb, the change of Up and down valence quark chemical potential.
          R2pi-1 = 2dUu-2dUb ~=10^(-3)*T 

          R2p -1 = 4dUu+2dUb ~= 1.5x10^(-3)*T 

          Double ratios are from Yang’s result. 

         Then 

         dUu = 4x10^(-4)*T 

         dUb = -10^(-4)*T

         That is a very small number.
