- Analysis of 1/M corrections aligns with HQET predictions
- Preliminary results suggest reliable decay constant estimates

## Abstract

We present {\it preliminary} results for the decay constants of heavy-light mesons using NRQCD heavy and tadpole improved Clover light quarks. A comparison is made with data obtained using Wilson light quarks. We present an analysis of the 1/M corrections to the decay constants in the static limit and compare with the predictions of HQET.
