MCPLOTS
MCPLOTS is intended as a simple browsable repository of
MC (Monte Carlo) plots comparing High Energy Physics event generators
to a wide variety of available experimental data,
for tuning and reference purposes. Apart from individual plots contained in papers
and presentations, there has so far not been any central database where people can
quickly see how tune X of version Y of generator Z looks on distribution
D. The idea with mcplots is to provide such a repository,
mainly based on the RIVET analysis tool.
On each page, selected by clicking in the menu on the left, you will
see a number of plots at different collider energies, comparing a set of
default generators/tunes to each other and to the data (if there is
any). If data for several different fiducial cuts are available at the
same energy, these will be arranged horizontally. At
the top of the page, you can select other generator/tune groups. The
default ("Main") is a comparison of the main generators. Each
additional tab then gives access to illustrations of more specialized
tunes/variations for each generator.
The millions of different possible combinations of beam energies, cuts,
generators, versions, and tunes, means that a lot of attention has been paid
to how to simplify the site, in particular how to organize the site visually,
and how to minimize the number of user clicks/inputs required to get what you
want. The current site is based on a prototype developed by P. Skands in the
context of workshops in Les Houches and Perugia [LH08,Ska10], but obviously
it also draws heavily on the lessons and tools developed as part of the JetWeb
project, in particular the RIVET analysis tool. The result is intended to look and feel
much like any old-style browsable/clickable set of pages,
with the more advanced technologies it is based on having been hidden 'under the
hood', for the most part.
Ultimately, we aim to include a possibility for more interactive use
of the site, with a special "USER" generator/tune group in which users can
compose their own comparisons and even upload their own files for
overplotting.
