Parton showers with quantum interference: leading color, with spin
We have previously described a mathematical formulation for a parton shower based on the approximation of strongly ordered virtualities of successive parton splittings. Quantum interference, including interference among different color and spin states, was included. A practical numerical implementation strategy was left unspecified. In a subsequent paper, we showed that if we add the further ap...
متن کاملParton showers with quantum interference: leading color, spin averaged
We have previously described a mathematical formulation for a parton shower based on the approximation of strongly ordered virtualities of successive parton splittings. Quantum interference, including interference among different color and spin states, is included. In this paper, we add the further approximations of taking only the leading color limit and averaging over spins, as is common in p...
متن کاملCoherent Parton Showers with Local Recoils
We outline a new formalism for dipole-type parton showers which maintain exact energy-momentum conservation at each step of the evolution. Particular emphasis is put on the coherence properties, the level at which recoil effects do enter and the role of transverse momentum generation from initial state radiation. The formulated algorithm is shown to correctly incorporate coherence for soft gluo...
متن کاملQCD matrix elements + parton showers
We propose a method for combining QCD matrix elements and parton showers in Monte Carlo simulations of hadronic final states in ee annihilation. The matrix element and parton shower domains are separated at some value yini of the jet resolution, defined according to the kT -clustering algorithm. The matrix elements are modified by Sudakov form factors and the parton showers are subjected to a v...
متن کاملNLO parton showers and subtractive techniques
Motivated by asking how to combine parton showers with nonleading QCD matrix elements, we discuss a subtractive technique based on gauge-invariant Wilsonline operators and how this can be used to treat the soft region. For precision phenomenology at future high energy colliders, it will be valuable to construct Monte Carlo event generators in which next-to-leading-order (NLO) QCD corrections ca...
