Mass spectrum of spin-one hadrons in dense two-color QCD: Novel predictions by extended linear sigma model

Daiki Suenaga, Kotaro Murakami, Etsuko Itou +1

We construct an extended version of the linear sigma model in such a way as to describe spin-$1$ hadrons as well as spin-$0$ hadrons in two-color QCD (QC${}_2$D) by respecting the Pa…
