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.

Factorization theorem relating Euclidean and light-cone parton distributions [PDF]
Physical Review D, 2018 In a large momentum nucleon state, the matrix element of a gauge-invariant Euclidean Wilson line operator accessible from lattice QCD can be related to the standard light-cone parton distribution function through the large-momentum effective theory ...

Child &Family Social Work, EarlyView.ABSTRACT Emergency foster care is a protection measure for children who are in a situation of abuse and/or neglect—or at imminent risk of it—that requires an assessment to make a decision. In Catalonia (Spain), emergency foster care placements are designed for children aged 0–6 and can last up to a maximum of 6 months.

Flavor hierarchy of parton energy loss in quark-gluon plasma from a Bayesian analysis
Physics Letters BThe quenching of light and heavy flavor hadrons in relativistic heavy-ion collisions probes the color and flavor dependences of parton energy loss through a color-deconfined quark-gluon plasma (QGP), and thus offers an important test of QCD-based ...

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.

Associated W±D(⁎) production at the LHC and prospects to observe double parton interactions
Physics Letters B, 2015 Associated production of charged gauge bosons and charged charmed mesons at the LHC is considered in the framework of kt-factorization approach. Theoretical predictions are compared with ATLAS data, and reasonably good agreement is found.

Collisions of protons with light nuclei shed new light on nucleon structure
, 2012 The high rates of multi-parton interactions at the LHC can provide a unique opportunity to study the multi-parton structure of the hadron. To this purpose high energy collisions of protons with nuclei are particularly suitable.

First Simultaneous Extraction of Spin-Dependent Parton Distributions and Fragmentation Functions from a Global QCD Analysis. [PDF]
Physical Review Letters, 2017 We perform the first global QCD analysis of polarized inclusive and semi-inclusive deep-inelastic scattering and single-inclusive e^{+}e^{-} annihilation data, simultaneously fitting the parton distribution and fragmentation functions using the iterative

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.
