Update notes for MadGraph5_aMC@NLO (in reverse time order)
5
OM: Allow new syntax for the param_card: instead of an entry you can enter "scan:[val1, val2,...]"
6
To perform a scan on this parameter.
7
OM: Having two mode for "output pythia8" one (default) for pythia8.2 and one for pythia8.1 (with --version=8.1)
5
OM: Allowing the proper NLO reweighting for NLO sample
6
RF: For NLO processes allow for multiple PDF and scales reweighting, directy by inputting lists
8
VH: Interfaced MadLoop to Samurai and Ninja (the latter is now the default)
9
HS: Turn IREGI to off by default
10
MZ: new NLO generation mode. It is more efficient from the memory and CPU point of
11
view, in particular for high-multiplicity processes.
12
Many thanks to Josh Bendavid for his fundamental contribution for this.
13
The mode can be enabled with
14
> set low_mem_multicore_nlo_generation True
15
before generating the process.
16
OM: Adding the possibility to use new syntax for tree-level processes:
17
QED==2 and QCD>2: The first allows to select exactly a power of the coupling (at amplitude level
18
While the second ask for a minimum value.
19
RF: In the PDF uncertainty for fixed-order NLO runs, variations of alphaS were not included.
20
OM: In MLM matching, fix a bug where the alpha_s reweighting was not fully applied on some events.
21
(This was leading to effects smaller than the theoretical uncertainty)
22
OM: Fixing the problem of using lhapdf6 on Mac
23
MZ: Faster interface for LHAPDF6
24
OM: Add support of epsilon_ijk in MadSpin
25
OM: Fix multiple problem with multiparticles in MadSpin
26
OM: Improve spinmode=None in MadSpin
27
OM: Update the TopEffTh model
28
MZ: Fix problem with slurm cluster
29
OM: Improve scan functionalities
30
PT: New way of handling Pythia8 decays
31
RF: Fixed a bug that resulted in wrong event weights for NLO processes when requiring
32
a very small number of events (introduced in 2.3.3)
33
OM: Allow to keep the reweight information in the final lhe file for future computation
34
MZ: updated FJcore to version 3.1.3 (was 3.0.5)
37
OM: Having two mode for "output pythia8" one (default) for pythia8.2 and one for pythia8.1 (with --version=8.1)
38
OM: Allow new syntax for the param_card: instead of an entry you can enter scan:[val1, val2,...]
39
To perform a scan on this parameter.
40
OM: Having two mode for "output pythia8" one (default) for pythia8.2 and one for pythia8.1 (with --version=8.1)
41
OM: Allow new syntax for the param_card: instead of an entry you can enter "scan:[val1, val2,...]"
42
To perform a scan on this parameter.
43
OM: Having two mode for "output pythia8" one (default) for pythia8.2 and one for pythia8.1 (with --version=8.1)
8
44
RF: Rewriting of job-control for NLO processes. Better accuracy estimates for FO processes
9
45
RF: Fix for factorisation scale setting in FxFx merging when very large difference in scale in the
10
46
non-QCD part of a process.
13
49
RF: Added an option to the run_card to allow for easier variation of the shower starting scale (NLO only).
14
50
RF: Fixed a problem in the setting of the flavour map used for runs with iAPPL >= 1.
15
51
RF: Allow for decay processes to compute (partial) decay widths at NLO accuracy (fixed order only).
16
OM: (SysCalc interface) Allow to bypass the pdf reweighting/alpsfact reweighting
17
MZ: fixed bug related to slurm clusters
52
OM: (SysCalc interface) Allow to bypass the pdf reweighting/alpsfact reweighting
53
MZ: fixed bug related to slurm clusters
18
54
OM: remove the addmasses.py script of running by default on gridpack mode.
19
55
if you want to have it running, you just have to rename the file madevent/bin/internal/addmasses_optional.py to
20
56
madevent/bin/internal/addmasses_optional.py and it will work as before. (Do not work with SysCalc tag)
21
57
OM: make the code compatible with "python -tt" option
24
VH: Finalized the MG5aMC-GoSam interface
60
VH: Finalized the MG5aMC-GoSam interface
27
63
OM: Improve reweighting module. (https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/Reweight)
