. Settings different from zero and one are intended
for debugging purposes and hence should not be used for normal runs.
option
0 : No runtime output.
option
1 : Normal runtime output. Warnings and errors are
printed, but no additional diagnostic output is given.
option
2 : Enhanced runtime output. As for =1, but limited
additional diagnostic info is given. Also, internal VINCIA
diagnostics histograms are booked and filled, especially for
matching. These can be printed by the user at any time (e.g., after
a run) using the VinciaPlugin::printHistos()
method.
option
3 : As for =2, but as much diagnostic
output as possible is given for each error or warning.
Also, a consistency check is added
to each branching by reclustering the resulting momenta back using the
corresponding inverse kinematics map and checking that the original
momenta are recovered within the desired numerical
precision.
option
4 : As for =3. And: each prepare()
and pTnext()
call is explicitly announced, with system
number and restart scale printed out, respectively. .
option
5 : As for =4. And: momentum listings are printed for
each configuration that violates P < 1.
option
6 : As for =5. And: each main function call is
explicitly announced with begin and end printed to output.
option
7 : As for =6. And: most function calls are explicitly
announced with begin and end printed to output
(still only partly implemented).
option
8 : As for =7. And: last semi-sensible level of output.
option
9 : As for =8. And: all possible output.

, VINCIA will automatically
use modified gluon emission antenna functions, in which the Eikonal (soft)
terms have been subtracted out, for the showers off the hardest
interaction. The gluon splitting antennae and the gluon emission
antennae for radiation inside resonance decays (and for showers off
MPI) are left
unmodified. Since the modified gluon emission antennae no longer contain
a soft singularity, this will NOT generate the correct DGLAP evolution
if used together with normal matrix elements for the hard
process. This option is therefore only intended for use together with
matrix element events in which the soft Eikonal has already been
resummed, such as when VINCIA is used together with J. Andersen's
high-energy-limit matrix elements. Since these matrix element
expressions are correct in the high-y-per-jet limit,
we have dubbed this running mode HyperJet
.
