Hello everybody, I have analyzed pi+pi- with event mixing today. The results are not so good and understandable. I attach here the pi+pi- invariant mass distribution after all the selection criteria on 100.000 generated events. We expect to see a peak at 3.1 GeV.
Hello everybody, I have run the event mixing data available on the GRID for the STT for the pbarp->pi+pi- analysis. I have collected the plots into a pdf file that you can find in attachment. For the pbarp->2(pi+pi-) I have still some not good results. I attach the invariant mass of the four pions. Cheers, Elisa
