Energy resolution of single Difference among gldapr08, gldprim_v04, and j4ldc_v04, LDCPrim are negligible Energy resolution of k 0 L ; Resolution can not be determined by fit due to LCPhysicsList feature By point-by-point comparison, –differences among gld/gld’/j4ldc below ~20 GeV is 5% –at 100 GeV, it is ~20% and can be explained by different interaction length GLD(6.79 ) J4LDC(5.67 ) 28 Akiya Miyamoto, KEK 2nd ILD WS, Cambridge, 12/9/2008
