%0 Journal Article %T Effect of Vector Meson Mass Decrease on Superfluidity in Nuclear Matter %A Tomonori Tanigawa %A Masayuki Matsuzaki %J Physics %D 1999 %I arXiv %X $^1S_0$ pairing in nuclear matter is investigated by taking the hadron mass decrease into account via the ``In-Medium Bonn potential'' which was recently proposed by Rapp et al. The resulting gap is significantly reduced in comparison with the one obtained with the original Bonn-B potential and we ascertain that the meson mass decrease is mainly responsible for this reduction. %U http://arxiv.org/abs/nucl-th/9901013v1
