Description
The LHC collides hadrons, bound states of colored particles (quarks and gluons). Therefore every analysis, whether a measurement or a search for new physics, needs an understanding of QCD dynamics. QCD effects can be important in the production and/or the decay of the particles being measured or sought and in calculating the (often huge) backgrounds.
General-purpose event generators are essential tools in any LHC analysis. One of the major components of these programs is the parton shower. The parton shower evolves the partonic final state from alarge scale to low scales and is the only perturbative part of the event generators that can be derived from first principles. It is essential to understand parton shower algorithms in more details and to develop more accurate tools for the LHC in order to reduce the theoretical uncertainties.
In this talk I review the design principles of the parton shower algorithms and discuss a new program that is based on color dipoles (beyond the leading-color approximation) with global momentum balancing and massive partons both in the initial and final states.
