Abstract: Let $ G$ be the unramified unitary group in three variables defined over a $ p$-adic field $ F$ with $ p \neq 2$. Gelbart, Piatetski-Shapiro and Baruch attached zeta integrals of Rankin-Selberg type to irreducible generic representations of $ G$. In this paper, we formulate a conjecture on $ L$- and $ \varepsilon $-factors defined through zeta integrals in terms of newforms for $ G$, which is an analogue of the result by Casselman and Deligne for $ \mathrm {GL}(2)$. We prove our conjecture for the generic supercuspidal representations of $ G$.
