Book excerpt: New preliminary BaBar results for rare leptonic decays B[sup -][yields] K[sup -][nu][bar[nu]] and B[sup 0][yields][ell][sup+][ell][sup -] are reported. Using data collected at the[Upsilon](4S) with the BaBar detector, no evidence for a signal was found yielding the corresponding upper limits at the 90% confidence level:[Beta](B[sup -][yields] K[sup -][nu][bar[nu]])
