SEMINAR     Friday, June 10th h. 16.00  Aula Fisica del Nucleo, building 22         Dr. Sergio Pereira, Sao Paulo U. - Brazil           Monte Carlo Simulation for the background of the $\gamma d \rightarrow \Theta^+ \Lambda$ reaction using the g10 data.             Abstract The $\gamma d \rightarrow \Theta^+ \Lambda$ is one of the reactions under study for the g10 experiment at CLAS, with the goal to search for evidence of a possible narrow exotic resonace. A Monte Carlo study is being developped to see if known resonances, in combination with simple kinematical cuts, could give raise to an eccess of events in the mass region of the $K^+ n$ system around $1.5$~ GeV. The Monte Carlo description will be presented.
