Description
Due to the fact, that experimental setups are usually not suited to cover the
complete full solid angle, event generators are very important tools for
experiments. Here, theoretical calculations provide valuable input as they
can describe specific distributions for parts of the kinematic variables very
precicely. The caveat is that an event has several degrees of freedom
which can be correlated. Practically, the experimental physics need a tool in
hand which allows for the exchange of almost all kinematic variables with a
manageable user interface.
Recently, the user-friendly Pluto event generator was re-designed in order to
introduce a more modular, object-oriented structure, thereby making additions
such as new particles, decays of resonances, new models up to modules for
entire changes easily applicable. Overall consistency is ensured by a plugin-
and distribution manager.
One specific feature of Pluto is that we do not use monolithic decay models
but allow for the splitting into different models in a very granular way
(e.g. to exchange form factors or total cross sections). This turned out to be
a very important tool in order to check various scenarious among with measured
data, which will be outlined with a few examples
Therefore Pluto allows for the attachment of secondary models for all kinds of
purposes. Here, a secondary model is an object for a particle/decay returning
a (complex) number as a function of a defined number of values. All models are
connected via a relative data base.
All features can be employed by the user without re-compiling the package,
which makes Pluto extremely configurable.
In our contribution, we present the new structure for the Pluto event
generator, originally intended to work for experiment proposals but now
upgraded to allow for the implementation of user-defined functions and models.
Summary
In our contribution, we present the new structure for the Pluto event
generator for hadronic interactions, originally intended to work for experiment proposals but now
upgraded to allow for the implementation of user-defined functions and models.
