We have studied the zero-temperature statistics of charge transfer between
the two edges of Quantum Hall liquids with filling factors Ξ½0,1β=1/(2m0,1β+1) forming Mach-Zehnder interferometer. The known Bethe ansatz
solution for symmetric interferometer is used to obtain the cumulant-generating
function of charge at constant voltage V between the edges. Its low-V
behavior can be interpreted in terms of electron tunneling, while its large-V
asymptotics reproduces the m-state dynamics (mβ‘1+m0β+m1β) of
quasiparticles with fractional (for m>1) charge and statistics. We also
analyze the transition region between electrons and quasiparticles.Comment: 5 two-column pages in RevTex4, 2 eps figures, final version with
