Query: Greiter replies to Demler, Zhang, Meixner, and Hanke   In a comment on my recent manuscript on the pi-particle [cond-mat/9705049],
Demler et al. [cond-mat/9705191] argued that there is a correction to the
chemical potential which enters the expression for the energy of the
pi-particle given in [Demler and Zhang, Phys. Rev. Lett. 77, 4126 (1995)]. This
is shown to be incorrect. I further offer an interpretation for the low-energy
resonances observed by Meixner et al. [cond-mat/9701217] in the pi-pi
correlation function in a finite-size Hubbard cluster at low electron
densities.
