Insights on d mu t sticking from d mu d stripping and mu He-3 capture

Data from the recent PSI high statistics experiment on d mu d fusion are us ed to measure the stripping process in d mu d --> n + mu He-3 and test curr ent calculations of the stripping process. The PSI results in mu He-3 captu re are also used to remove a troubling background from this measurement. Co mbination of these results with the old d mu t sticking analysis slightly r aise and improve that result to omega(s) = (0.58 +/- 0.04)% and indicate th at theory and experiment can meet if theoretical stripping is increased onl y at the beginning of the track. This conclusion is in accord with the new stripping calculations where excited state stripping is increased significa ntly.
