Three independent searches for new physics using data collected at BABAR arepresented. Firstly, two searches for dark matter and baryogenesis:$B^{0}\rightarrow \Lambda + \psi_{D}$ and $B^{+} \rightarrow p + \psi_{D}$ aredetailed, where $\psi_{D}$ is a new dark fermion. Neither signal is observedand new upper limits on the branching fractions, at the 90 $\%$ confidencelevel (C.L), are placed at $\mathcal{O}(10^{-5} - 10^{-6})$ across the massrange $1.0< m_{\psi_{D}}<4.3$ GeV/c$^{2}$. Secondly, new limits on thecoupling, $g_{aW}$, of an axion-like particle ($a$) to the $W$ boson, at the 90$\%$ C.L, are presented at $\mathcal{O}(10^{-5})$ GeV$^{-1}$ for $a$ masses inthe mass range 0.175 $<m_{a}<$ 4.78 GeV/c$^{2}$. Thirdly, a model-independentsearch for heavy neutral leptons (HNL) found new upper limits at the 95 $\%$C.L on the extended Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix element,$|U_{\tau 4}|^{2}$, which depend on the HNL mass hypothesis and vary from $2.31\times 10^{-2}$ to $5.04 \times 10^{-6}$, across the mass range $100 < m_{4} <1300$ MeV/c$^{2}$, with more stringent limits on higher HNL masses.
