Understanding the properties of the strange Λ* baryon resonances is a long-standing and fascinating problem. Λ_c charm-baryon semileptonic weak decays to these resonances are highly sensitive to their internal structure and can be used to test theoretical models. We have performed the first lattice-QCD computation of the form factors governing Λ_c semileptonic decays to a Λ* resonance: the Λ*(1520), which has negative parity and spin 3/2. Here we present the resulting Standard-Model predictions of the Λ_c → Λ*(1520)$$\ell^+ν_\ell$$ differential and integrated decay rates as well as angular observables. Furthermore, by combining the recent BESIII measurement of the Λc → Xe⁺ν_e inclusive semipositronic branching fraction [Phys. Rev. Lett. 121, 251801 (2018)] with lattice-QCD predictions of the Λ_c → Λe⁺ν_e, Λ_c → ne⁺ν_e, and Λ_c → Λ*(1520)e⁺ν_e decay rates, we obtain an upper limit on the sum of the branching fractions to all other semipositronic final states. In particular, this upper limit constrains the Λ_c → Λ*(1405)e⁺ν_e branching fraction to be very small, which maybe another hint for a molecular structure of the Λ*(1405).
