Antenna Approach to Parton Showers
Séminaire commun au LAL et au LPT présenté par Michael E.Peskin (SLAC).
Mardi 4 octobre à 11h
Friday 30 September 2011
In a conventional parton shower, the basic move is a 1->2 splitting radiating a quark or gluon in accord with Altarelli-Parisi evolution. An antenna parton shower is a parton shower in which the basic move is a 2->3 splitting in which a color dipole coherently radiates a quark or gluon.
In this talk, I will describe the formalism of antenna showers, including inclusion of spin and of massive particles, and show some results of the implementation.
