Using data samples of 102 million ϒ⁡(1⁢𝑆) events and 158 million ϒ⁡(2⁢𝑆) events collected by the Belle detector at the KEKB asymmetric-energy 𝑒+⁢𝑒− collider, we search for [𝑢⁢𝑑⁢𝑠⁢𝑐$$\overline{𝑐}$$ ] pentaquark states decaying to 𝐽/𝜓⁢Λ. Using the first observations of ϒ⁡(1⁢𝑆,2⁢𝑆) inclusive decays to 𝐽/𝜓⁢Λ, we find evidence of the 𝑃_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)⁰ state with a local significance of 3.3 standard deviations, including statistical and systematic uncertainties. We measure the mass and width of the 𝑃_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)⁰ to be (4471.7±4.8±0.6) MeV/𝑐² and (22 ±13 ±3) MeV, respectively. The branching fractions for 𝑃_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)⁰ production are measured to be ℬ⁡[ϒ⁡(1⁢𝑆)→𝑃_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)0/ $$\overline{𝑃}$$_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)⁰+anything]=(3.5±2.0±0.2)×10⁻⁶ and ℬ⁡[ϒ⁡(2⁢𝑆)→𝑃_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)⁰/$$\overline{𝑃}$$_{𝑐$$\overline{𝑐}$$𝑠}⁢(4459)⁰+anything]=(2.9±1.7±0.4)×10⁻⁶. The inclusive branching fractions of ϒ⁡(1⁢𝑆,2⁢𝑆) →𝐽/𝜓⁢Λ/$$\overline{Λ}$$ are measured to be ℬ⁡[ϒ⁡(1⁢𝑆) →𝐽/𝜓⁢Λ/$$\overline{Λ}$$ +anything] =(36.9 ±5.3 ±2.4) ×10⁻⁶ and ℬ⁡[ϒ⁡(2⁢𝑆) →𝐽/𝜓⁢Λ/$$\overline{Λ}$$ +anything] =(22.3 ±5.7 ±3.1) ×10⁻⁶. We measure the visible cross section 𝜎⁡(𝑒+⁢𝑒−→𝐽/𝜓⁢Λ/ $$\overline{Λ}$$ +anything)=(90±14±6) fb for the continuum production at √𝑠 =10.52 GeV. In all cases, the first uncertainties are statistical and the second are systematic.
