Abstract

We calculate the mass and residue of the nucleon in nuclear matter in the frame work of QCD sum rules using the nucleon’s interpolating current with an arbitrary mixing parameter. We evaluate the effects of the nuclear medium on these quantities and compare the results obtained with the existing theoretical predictions. The results are also compared with those obtained in vacuum to find the shifts in the quantities under consideration. Our calculations show that these shifts in the mass and residue are about and , respectively.
