  "abstract": "We study the possible existence of chiral partners in the spin-$\\thalf$ sector of the baryon spectrum. We consider a quartet scheme where four spin-3/2 baryons, $P_{33}$, $D_{33}$, $D_{13}$ and $P_{13}$, group into higher-dimensional chiral multiplets $(1, \\half)\\oplus (\\half,1)$ with a mirror assignment. With an effective $SU(2)_R\\times SU(2)_L$ Lagrangian, we derive constraints imposed by chiral symmetry together with the mirror assignment on the masses and coupling constants of the quartet. Using the effective Lagrangian, we try to find a set of baryons suitable for the chiral quartet. It turns out that two cases reasonably agree with the mass pattern of the quartet: ($\\Delta(1600)$, $\\Delta(1940)$, $N(1520)$, $N(1720)$) and ($\\Delta(1920)$, $\\Delta(1940)$, $N(2080)$, $N(1900)$).",
