Title: What is $$\Delta m^2_{ee}$$ ?

Here, the current short baseline reactor experiments, Daya Bay and RENO (Double Chooz) have measured (or are capable of measuring) an effective Δm2 associated with the atmospheric oscillation scale of 0.5 km/MeV in electron antineutrino disappearance. In this paper, I compare and contrast the different definitions of such an effective Δm2 and argue that the simple, L/E independent definition given by Δmee2≡cos2θ12Δm312+sin2θ12Δm322, i.e. “the νe weighted average of Δm312 and Δm322,” is superior to all other definitions and is useful for both short baseline experiments mentioned above and for the future medium baseline experiments JUNO and RENO-50.
