Description
Overview on Parton Branching, overview on traditional Parton shower, parton shower accuracy and consistency, TMDs from PSMC
We assess the effect of QCD/QED interference effects in fixed color parton showers with tree level matrix element corrections.
Transverse Momentum Dependent (TMD) parton distribution is a very powerful concept for the description of low and high transverse momentum effects in high energy collisions. The Parton Branching (PB) method provides TMD distributions that can be used in parton shower simulations, as already implemented in CASCADE Monte Carlo event generator.
We develop a method, PS2TMD, that allows...
We present a study of intrinsic kt effects in DY production from very low DY masses up to the Z-boson mass, covering a large range of center-of-mass energies from \sqrt{s} = 40 GeV up to LHC energies.
The description of measurements from different experiments is studied with MCatNLO supplemented with Pythia8 as well as with Parton Branching TMDs.
An energy dependent intrinsic kt width is...
Particle-particle correlations, especially rapidity-rapidity correlations was already an important tool for hadron collider physics since the early 70s. Recently, we studied one-particle rapidity distributions and two-particle rapidity-rapidity correlations at hadron colliders revisiting one of the old models, the Chew-Pigniotti multiperipheral model and we were surprised to realize that the...
