[Vincia-announce] Vincia 1.2.01 now available

[Peter Skands (CERN)]

Dear All,

Version 1.2.01 of the Vincia Code has now been released, and can be 
downloaded at:
http://www.hepforge.org/downloads/vincia

This is intended to be the last public release before the introduction 
of initial-state radiation, for hadron-hadron physics. Since the 
initial-state antenna shower will be based on massless partons, this 
version also introduces a massless underlying formalism for final-state 
partons, contrary to earlier versions that included a more elaborate 
treatment of final-state mass effects. Phase-space constraints and 
universal mass-correction terms in the antenna functions are still 
included, but fully massive antenna functions and massive matrix-element 
corrections have been disabled for the time being, as these require 
explicitly massive 4-vectors. A new default “nikhef3” tune is included 
as well, and gives nearly the same description as previously, although a 
few b-specific observables have worsened slightly. This will be the 
baseline for comparisons of the pp version. Further minor updates to the 
VinciaRoot plotting tool, for better distinguishability of curves.

The new version is compatible with versions 8.200 - 8.205 of Pythia, 
which can be downloaded at:

Sincerely,
The Vincia Collaboration
