  • The PID TAG agreed that it uses for the expression of separtaion power the resolution power that discribes the distance in sigma of two Gaussian distributions (with the same sigma and height) as it is used in most of the experiments and is discribed and used in literature (T. Ypsilantis et al., NIM A 343 (1994) 30-51 and P. Glaessel and others: NIM A 433 (1999) 17-23 and the Particle Data Book) with the additional remark that in this case (with a cut in the middle between both distributions) a 4 sigma separation means a missidentification of 2.3%.

  • The PID TAG agreed on the separation power discribing the distance of two Gaussian distributions with the same sigma and height. Based on the most of the experiments it is discribed eg. in T. Ypsilantis et al., NIM A 343 (1994) 30-51, P. Glaessel and others, NIM A 433 (1999) 17-23, and the Particle Data Book. Taking a separation of 4 sigma with a cut in the middle between both distributions results in a missidentification of 2.3%.
 
  • The next PID TAG VRVS meeting takes place end of October 2007
