Two-loop evolution kernels for colour dependent double parton distributions
Journal of High Energy Physics, 2023 A key ingredient in the description of double parton distributions is their scale dependence. If the colour of each individual parton is summed over, the distributions evolve with the same DGLAP kernels as ordinary parton distributions. This is no longer

Child &Family Social Work, EarlyView.ABSTRACT Fifty years after the formation of England's child protection system, the country continues to reel from new instances of high‐profile child death tragedies where children have been harmed despite practitioners complying with the processes and procedures designed to protect them.

Spin correlations in parton-parton scattering
Nuclear Physics B, 1988 Abstract The sum over the helicities of partons in QCD jet production gives rise to quantum mechanical interference effects, leading to correlations between the azimuthal angles of the branching planes of partons within jet cascades. In this paper, it is shown how to extend previous work on calculating correlations within a jet to the case of parton ...

Problematising ‘Vulnerability’ in Women's Prisons
The Howard Journal of Crime and Justice, EarlyView.ABSTRACT ‘Vulnerability’ is a commonly used but little understood term in the field of social policy and beyond. The refocusing of our criminal justice system around notions of ‘vulnerability’ has had wide‐reaching consequences which often escape both academic and political attention.

Double parton distributions in the pion in the Nambu–Jona-Lasinio model
Journal of High Energy Physics, 2019 Two-parton correlations in the pion, a non perturbative information encoded in double parton distribution functions, are investigated in the Nambu–Jona-Lasinio model.

Momentum conservation and unitarity in parton showers and NLL resummation
Journal of High Energy Physics, 2018 We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observables in electron-positron annihilation.

Sum rule improved double parton distributions in position space
European Physical Journal C: Particles and Fields, 2020 Models for double parton distributions that are realistic and consistent with theoretical constraints are crucial for a reliable description of double parton scattering.

Journal of Fish Biology, EarlyView.Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Journal of Personality, EarlyView.ABSTRACT Objectives Counter‐empathy involves responding to others' assumed emotions incongruently. Research on dispositional counter‐empathy predominantly focuses on specific counter‐empathic constructs without clearly mapping its cardinal dimensions.
