We present the study of \(\bar{B}^{0} \to \Sigma_{c}(2455)^{0,++} \pi^{\pm} \bar{p}\) decays based on \(772\times 10^{6}\) \(B\bar{B}\) events collected with the Belle detector at the KEKB asymmetric-energy \(e^+e^-\) collider. The \(\Sigma_{c}(2455)^{0,++} \) candidates are reconstructed via their decay to \(\Lambda_{c}^{+} \pi^{\mp}\) and \(\Lambda_{c}^{+}\) decays to \(pK^{-}\pi^{+},~pK_{S}^{0},\) and \(\Lambda\pi^{+}\) final states. The corresponding branching fractions are measured to be \({\cal B}(\bar{B}^{0} \to \Sigma_{c}(2455)^{0} \pi^{+} \bar{p}) = (1.09 \pm 0.06 \pm 0.07)\times10^{-4}\) and \({\cal B}(\bar{B}^{0} \to \Sigma_{c}(2455)^{++} \pi^{-} \bar{p}) = (1.84\pm 0.11 \pm 0.12)\times 10^{-4}\), which are consistent with the world average values with improved precision. A new structure is found in the \(M_{\Sigma_{c}(2455)^{0,++}\pi^{\pm}}\) spectrum with a significance of \(4.2\sigma\) including systematic uncertainty. The structure is possibly an excited \(\Lambda_{c}^{+}\) and is tentatively named \(\Lambda_{c}(2910)^{+}\). Its mass and width are measured to be \((2913.8 \pm 5.6 \pm 3.8)\) MeV/\(c^{2}\) and \((51.8\pm20.0 \pm 18.8)\) MeV, respectively. The products of branching fractions for the \(\Lambda_{c}(2910)^{+}\) are measured to be \({\cal B}(\bar{B}^{0} \to \Lambda_{c}(2910)^{+}\bar{p})\times{\cal B}(\Lambda_{c}(2910)^{+} \to \Sigma_{c}(2455)^{0}\pi^{+}) = (9.5 \pm 3.6 \pm 1.6)\times 10^{-6}\) and \({\cal B}(\bar{B}^{0} \to \Lambda_{c} (2910)^{+}\bar{p})\times {\cal B}(\Lambda_{c}(2910)^{+} \to \Sigma_{c}(2455)^{++}\pi^{-}) = (1.24 \pm 0.35 \pm 0.10)\times 10^{-5}\). Here, the first and second uncertainties are statistical and systematic, respectively.
