Abstract
The TPC/Two-Gamma Collaboration has measured the inclusive cross section for production of charmed D*± mesons in photon-photon collisions. The reaction utilized was e+e-→e+e-D*±X, with D*±→DOπ+-, DO→K-+π ±, and either zero or one outgoing e± detected. The result, σ(e+e- → e+e-D*±X) = 74±26±19 pb, is in agreement with the quark parton mo del prediction for e+e- → e+e-cc, combined with a Lund model for the hadronization of the charmed quarks.
