Photoproduction of the (Positive, Negative) D* Meson

Using the broad band beam at FNAL, we have observed the photoproduction of the D('*+) (and D('*-)) meson, where D('*+) (--->) D('0)(pi)('+) and D('0) (--->) K('-)(pi)('+) (143 (+OR-) 20 events) or D('0) (--->) K(,s)(pi)('+)(pi)('-) (35 (+OR-) 11 events). The observation exploited the small D('*+)-D('0) mass difference to reduce the combinatoric background by 3 orders of magnitude. A variety of analysis techniques are presented to demonstrate that the D('*+) is created by a diffractive pair production mechanism, with a cross section given by
