Hi Olivier and Madgraph team I've been running several test samples with the new released MGv2.6.1 I haven't changed any of the card infos. Only thing I did was generate p p > t t~ [QCD] with MadSpin on (default madspin card decaying t, t~) Please take a look at this MG5_aMC>generate p p > t t~ [QCD] INFO: Generating FKS-subtracted matrix elements for born process: g g > t t~ [ all = QCD ] (1 / 9) INFO: Generating FKS-subtracted matrix elements for born process: u u~ > t t~ [ all = QCD ] (2 / 9) INFO: Generating FKS-subtracted matrix elements for born process: c c~ > t t~ [ all = QCD ] (3 / 9) INFO: Generating FKS-subtracted matrix elements for born process: d d~ > t t~ [ all = QCD ] (4 / 9) INFO: Generating FKS-subtracted matrix elements for born process: s s~ > t t~ [ all = QCD ] (5 / 9) INFO: Generating FKS-subtracted matrix elements for born process: u~ u > t t~ [ all = QCD ] (6 / 9) INFO: Generating FKS-subtracted matrix elements for born process: c~ c > t t~ [ all = QCD ] (7 / 9) INFO: Generating FKS-subtracted matrix elements for born process: d~ d > t t~ [ all = QCD ] (8 / 9) INFO: Generating FKS-subtracted matrix elements for born process: s~ s > t t~ [ all = QCD ] (9 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: g g > t t~ QCD<=2 [ all = QCD ] (1 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: u u~ > t t~ QCD<=2 [ all = QCD ] (2 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: c c~ > t t~ QCD<=2 [ all = QCD ] (3 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: d d~ > t t~ QCD<=2 [ all = QCD ] (4 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: s s~ > t t~ QCD<=2 [ all = QCD ] (5 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: u~ u > t t~ QCD<=2 [ all = QCD ] (6 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: c~ c > t t~ QCD<=2 [ all = QCD ] (7 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: d~ d > t t~ QCD<=2 [ all = QCD ] (8 / 9) INFO: Generating virtual matrix elements using MadLoop: INFO: Generating virtual matrix element with MadLoop for process: s~ s > t t~ QCD<=2 [ all = QCD ] (9 / 9) INFO: Generated 9 subprocesses with 136 real emission diagrams, 11 born diagrams and 124 virtual diagrams MG5_aMC>output TEST INFO: Writing out the aMC@NLO code, using optimized Loops INFO: directory /home/shjeon/Desktop/Physics/MadGraph/MG5_aMC_v2_6_1/TEST already exists.
