PCAC in Nuclear Medium and the Lovelace-Shapiro-Veneziano formula
J. Pasupathy
Abstract
A simple way to enforce the Adler zero condition for pion amplitudes in the nuclear medium is to use the Lovelace quantization condition but with modified Regge Slope α' This latter is related to change in the gluon condensate. Increasing nuclear density leads to a relative increase in the Regge Slope α' Denoting this increase by a scale factor λ, the drop in the ρ-mass, Δ-N mass difference, increase in ππ scattering length, decrease of pion decay constant etc. are simply related to λ.
