摘要：

We set up a zero recoil sum rule to constrain the form factors of the Lambda(b) -> Lambda(c) transition. Our results are compared with the recent lattice calculation for these transitions. We find the same situation as in the case for B -> D*: The lattice results practically saturate the sum rules, leaving basically no room for excited states. (C) 2015 The Authors.
