Measurement of parton shower observables with OPAL [PDF]

, 2017
A study of QCD coherence is presented based on a sample of about 397,000 e+e- hadronic annihilation events collected at √s = 91 GeV with the OPAL detector at LEP.

Parton showers and matching uncertainties in top quark pair production with Herwig 7

European Physical Journal C: Particles and Fields, 2019
We evaluate the theoretical uncertainties in next-to-leading order plus parton shower predictions for top quark pair production and decay in hadronic collisions.

Collider events on a quantum computer

Journal of High Energy Physics, 2022
High-quality simulated data is crucial for particle physics discoveries. Therefore, parton shower algorithms are a major building block of the data synthesis in event generator programs.

Summing threshold logs in a parton shower [PDF]

, 2016
When parton distributions are falling steeply as the momentum fractions of the partons increases, there are effects that occur at each order in $\alpha_s$ that combine to affect hard scattering cross sections and need to be summed.

Resampling algorithms for high energy physics simulations

European Physical Journal C: Particles and Fields, 2020
We demonstrate that the method of interleaved resampling in the context of parton showers can tremendously improve the statistical convergence of weighted parton shower evolution algorithms.

Transverse Momentum Dependent and collinear densities based on Parton Branching method

SciPost Physics Proceedings, 2022
We review the current status of collinear and Transverse Momentum Dependent densities based on the Parton Branching method. We investigate the performance of the PB-TMD evolution as well as PB-TMD parton shower with different configurations of the hard ...
