Initial State Parton Showers Beyond Leading Order

open access: yes, 2004
We derive a new method for initial-state collinear showering in Monte-Carlo event generators which is based on the use of unintegrated parton correlation functions.

Jet Quenching with Detailed Balance in a Thermal QCD Medium [PDF]

open access: yes, 2002
The effect of detailed balance in induced gluon radiation for an energetic parton propagating inside a quark-gluon plasma is discussed. The stimulated thermal gluon emission reduces while absorption increases the parton's energy.

Parton distributions with small-x resummation: evidence for BFKL dynamics in HERA data [PDF]

open access: yesThe European Physical Journal C, 2017
We present a determination of the parton distribution functions of the proton in which NLO and NNLO fixed-order calculations are supplemented by NLLx small-x resummation.

Parton recombination effect in polarized parton distributions

open access: yes, 2004
Parton recombination corrections to the standard spin-dependent Altarelli-Parisi evolution equation are considered in a nonlinear evolution equation. The properties of this recombination equation and its relation with the spin-averaged form are discussed.

Towards a quantum computing algorithm for helicity amplitudes and parton showers [PDF]

open access: yesPhysical Review D, 2020
The interpretation of measurements of high-energy particle collisions relies heavily on the performance of full event generators. By far the largest amount of time to predict the kinematics of multi-particle final states is dedicated to the calculation ...

Gaining analytic control of parton showers [PDF]

open access: yes, 2007
Parton showers are widely used to generate fully exclusive final states needed to compare theoretical models to experimental observations. While, in general, parton showers give a good description of the experimental data, the precise functional form of ...

TMD parton distributions from parton showers [PDF]

open access: yesProceedings of XXVII International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS2019), 2019
We present the determination of Transverse Momentum Dependent (TMD) parton distributions from Monte Carlo parton showers. We investigate the effective TMD distributions obtained from the PYTHIA8 and HERWIG6 parton showers and compare them to the TMD distributions determined within the Parton Branching method.

Assessing the intensity of Late Quaternary humid phases in the Nefud Desert, northern Arabia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The climate history of the major dryland zones of the world, such as the Saharo–Arabian Desert belt, plays a key role in the dispersal of early humans through these intermittently inhospitable regions. Here, we assess the relative intensity of Late Quaternary humid phases in northern Arabia through lithological, geochemical, palaeoecological ...
